The role of legal and moral norms to regulate the behavior of texting while driving

Despite a nationwide lawful effort to regulate texting-while-driving behavior, little change has been reported. This study assessed the effect of current legal enforcement on attitudinal and behavioral responses toward texting while driving in conjunction with potential influences of two types of perceived norms—legal and moral. An online survey was conducted with 313 college students recruited from three states where the history of a banning law of texting while driving varied (more than 3 years, less than 1 year, and none). The students self-reported perceived legal norm, perceived moral norm, perceived risk of texting while driving, frequency of texting while driving, attitude toward texting while driving, and intention of texting while driving. General linear model analyses revealed that the mere presence of legal enforcement showed a negative relationship with frequency of behavior only for the state with the banning law in effect more than 3 years. While the perceived legal norm showed inconsistent relationships with outcome variables, the perceived moral norm appeared most promising to discourage texting while driving among young drivers. A banning law for texting-while-driving behavior not only backfired on the actual behavior in a short-term effect, but also required a long-term exposure of the law to change the actual behavior among college students. On the other hand, cultivation of a moral norm to regulate the behavior of texting while driving is particularly encouraged in that the stable nature of this psychological variable can play a role to suppress possible reactance evoked by an external force. Policy makers are encouraged to harness their approach to regulate young drivers’ texting while driving with the strategy that appeals to the drivers’ moral beliefs rather than simply forcing them to comply with the law.     

Driving and gaze behavior while texting when the smartphone is placed in a mount: A simulator study

The aim of this study was to investigate how texting when the smartphone in a mount next to the wheel, negatively affects safe driving behavior and gaze behavior. In most countries hand-held phone use while driving is prohibited. However, when texting is not explicitly forbidden and only hand-held use is not allowed, drivers can still legally operate their smartphone with their fingers when it is placed in a mount which is attached to the dashboard or the windscreen. The effects on driving and gaze behavior of ‘dashboard-mount’ texting have hardly been investigated. Twenty-seven participants drove three short identical drives in a simulator while their driving behavior and gaze behavior was measured. This was a drive in which participants did not text (baseline drive), a drive while they texted with a smartphone in one hand (hand-held drive), and a drive in which they texted while the phone was placed in a dashboard-mount (dashboard-mount drive). Participants looked significantly more often at the smartphone during the dashboard-mount than during the hand-held drive. Total dwell time at the smartphone was significantly longer during the dashboard-mount than during the hand-held drive. There were no significant differences between the two texting drives in the number of glances longer than 2 s, the longest glance of each participant, and mean fixation duration at the smartphone. Total dwell time in the mirrors was significantly shorter during the two texting drives than in the baseline drive but did not differ between the two texting drives. The drivers showed poorer lateral control and varied their speed more in the two texting drives than in the baseline drive. They also drove significantly slower in the two texting drives than in the baseline drive. Finally, subjective workload was much higher in the two texting drives than in the baseline drive. The results indicate that dashboard-mount texting deteriorates the safe execution of the driving task to at least the same extend as hand-held texting does.     

Cell Phone-Related Near Accidents Among Young Drivers: Associations With Mindfulness

Cell phone use while driving (CPWD) has been shown to significantly reduce driver safety. This is a particular concern among young drivers who possess less driving experience and tend to engage in high rates of cell phone use. The present study identified psychological predictors of near accidents related to CPWD among a sample of 385 college student drivers. Participants answered a series of questions regarding their use of a cell phone while driving and completed measures of mindfulness, polychronicity, and intrusive thinking. Students who reported talking on their phone or texting more frequently while driving reported a higher incidence of near accidents related to each behavior. However, after controlling for CPWD, multiple regression analysis indicated that those who reported experiencing more cell phone-related intrusive thoughts also experienced more near accidents. Furthermore, two facets of mindfulness—acting with awareness and nonjudging of inner experience—were negatively associated with near accidents. These findings suggest that individuals who are more aware of the present moment and accepting of their affective responses may better regulate their attention while using a cell phone behind the wheel.     

Dual-task decrements in driving performance: The impact of task type,working memory,and the frequency of task performance

Driving while carrying out another (secondary) task interferes with performance, though the degree of interference may vary between tasks and individual drivers. In this study, we focused on two potentially interrelated individual difference variables that may play a role in determining dual-task interference: working memory capacity and the driver’s experience with the relevant secondary task. We used a driving simulator to measure interference, comparing single-task performance (driving alone) with driving performance during three secondary tasks: conversing on a handsfree cellphone, texting, and selecting a song on a touchscreen Mp3 player. Drivers also rated the difficulty of driving while carrying out each secondary task. For the individual difference variables, working memory was measured using the Operation Span test (OSPAN), and experience was assessed in terms of self-reported daily driving exposure and exposure to the relevant secondary tasks (frequency, duration). Overall, we found evidence of dual-task interference, though interference varied between tasks; the texting and Mp3 tasks produced significantly more interference than handsfree cellphone conversation. For the texting and Mp3 song selection tasks, interference was apparent in terms of increased steering variability, but for the Mp3 task there was also compensatory slowing, with drivers slowing down while carrying out the task. OSPAN performance and daily driving exposure were both covariates in predicting the amount of dual-task interference. However, our results suggest that in all but two cases, both involving the texting task, the effects of the OSPAN and the driving and secondary task exposure variables were independent rather than interrelated.     

Characteristics of college students who text while driving: Do their perceptions of a significant other influence their decisions?

IntroductionTexting while driving is a significant risk factor for automobile collisions. The use of cell phones is prevalent among young people and commonly reported when they drive.MethodA web-based survey of 861 college student drivers determined how texting was associated with other forms of risky driving, perceptions of risk, and their driving and texting interactions with a significant other.ResultsTexting drivers were more likely to engage in other risky driving behaviors, perceived less risk in texting and driving, felt more immune to traffic risks, and had friends who text and drive. Logistic regression analyses showed that even after adjusting for risky driving behaviors and perceived risk, texting drivers were significantly more likely to do so if they saw their significant other text and drive.ConclusionsTraffic safety campaigns need to address important social influences on this behavior.     

Even experienced phone users drive worse while texting – A driving simulator study

Several studies have clearly shown that texting on a mobile phone increases crash risk (e.g. Dingus et al., 2006; Victor et al., 2014). However, the frequency of texting while driving still remains high (e.g. Vollrath, Huemer, Teller & Likhacheva, 2016). One reason may be that drivers are convinced that they are able to manage this dual task due to their competency in driving and texting. From a theoretical point of view, this may be true within limits – two well-learned, automatically processed tasks may require so few resources most of the time that interferences may not occur.In order to test this assumption, a study with a standardized driving simulator task (the lane change task, LCT; Mattes, 2003) was done with n = 40 drivers selected for their driving experience and tested for their texting abilities. The effect of driving experience (high vs. low) and texting competence (high vs. low) on driving performance was examined in single (driving only) and dual-task (driving and texting) conditions. Additionally, a subjective assessment of one’s task performance was obtained. Texting on the mobile phone significantly impaired driving performance. While driving experience did not have an influence, the deteriorating effect of texting was significantly less pronounced in highly competent phone users. Interestingly, this objective effect was not found in the subjective assessment. Drivers with a high texting competence felt as impaired as drivers with a low texting competence. This is in line with the finding that even in this simple driving task their performance was still significantly deteriorated as compared to driving, only. Thus, it seems that the reason why people text while driving is not that they are not aware of the performance loss. However, this awareness of the possible risk does not seem sufficient to prevent them from texting while driving.     

Driving performance while using a mobile phone: A simulation study of Greek professional drivers

PurposeThe current study aims to assess the driving performance of professional drivers while using a mobile phone.Material and methodsA sample of 50 male professional drivers participated in the study. The sample was drawn conveniently from the professional drivers’ registries and the main taxi ranks. The inclusion criteria were: (a) age above 18 years, (b) possession of a driving license, (c) sufficient reading, writing, and communicating skills, (d) informed consent prior to participation. Laboratory tests were conducted using the VS500M driving simulator manufactured by Virage Simulation Inc. The intervention involved different tasks/assignments: (a) driving without using a mobile phone (Control time), (b) driving while having a conversation on the mobile phone, (Task_1), (c) driving while reading out loud text messages (Task_2) and, (d) driving while texting (Task_3). Differences in the driving performance between the control time and the time with assignments, were examined. The participants were evaluated on the followings outcome measures: (a) variation of the steering position per second, (b) following distance per second, (c) variation of the lateral lane position per second, and (d) sum of squared acceleration per second.ResultsThe analysis indicated that “variation of the steering position per second” was significantly affected by “text-message reading” [t(50) = −5.443; p < 0.0001] and “texting” [t(50) = −5.442; p < 0.0001]. A significant main effect was observed in terms of the “following distance per second” and the “variation of the lateral lane position per second” for all the three mobile phone assignments. Lastly, the “sum of squared acceleration per second” was significantly decreased during conversation on the phone [t(50) = 2.713; p = 0.009] as well as during texting [t(50) = 3.428; p = 0.001] as compared with the control time.ConclusionsThe study is among the few existing experimental studies in a country with one of the highest road fatalities in Europe but with limited evidence on road traffic behaviour. This study could guide the design of large-scale simulation studies aiming to explore the impact of mobile phone on driving behaviour.     

Analysis of vehicle-based lateral performance measures during distracted driving due to phone use

Distracted driving due to mobile phone use has been identified as a major contributor to accidents; therefore, it is required to develop ways for detecting driver distraction due to phone use. Though prior literature has documented various visual behavioural and physiological techniques to identify driver distraction, comparatively little is known about vehicle based performance features which can identify driver’s distracted state during phone conversation and texting while driving. Therefore, this study examined the effects of simple conversation, complex conversation, simple texting and complex texting tasks on vehicle based performance parameters such as standard deviation of lane positioning, number of lane excursions, mean and standard deviation of lateral acceleration, mean and standard deviation of steering wheel angle and steering reversal rates (for 1°, 5° and 10° angle differences). All these performance measures were collected for 100 licensed drivers, belonging to three age groups (young, mid-age and old age), with the help of a driving simulator. Effects of all the phone use conditions and driver demographics (age, gender and phone use habits) on the measures were analysed by repeated measures ANOVA tests. Results showed that 1°, 5° SRRs are able to identify all the distracted conditions except for simple conversation; while, 10° SSR can detect all the distracted conditions (including simple conversation). The results suggest that 10° SRR can be included in intelligent in-vehicle devices in order to detect distraction and alert drivers of their distracted state. This can prevent mobile phone use during driving and therefore can help in reducing the road accidents due to mobile phone distractions.     

It’s all in the mind: The relationship between mindfulness and nomophobia on technology engagement while driving and aberrant driving behaviours

This study investigated the relationship between mindfulness and nomophobia on technology engagement while driving and aberrant driving behaviours. Nine hundred and ninety participants completed an online survey (Female: 68.6%; Age: M = 51.2 years, SD = 15.7, Range = 18.0–84.0 years) that assessed mindfulness, nomophobia, technology engagement while driving, aberrant driving behaviour, and self-reported crashes and infringements during the past two years. Structural equation modelling (SEM) was used to examine the relationships between mindfulness and nomophobia, on one hand, with self-reported engagement with technology while driving and general aberrant driving behaviours (combination of errors, lapses and violations) on the other. The results of the SEM showed that, as expected, mindfulness shared negative relationships with nomophobia, engagement with technology and aberrant driving behaviours, while all other relationships were positive. In terms of engagement with technology, there were direct and indirect paths between nomophobia and mindfulness and engagement with technology. The results of this study demonstrate the positive influence mindfulness can have on nomophobia, engagement with technology while driving, and dangerous driving behaviours that have been associated with crash risk. Mindfulness practices may reduce the effect of nomophobia on engagement with technology while driving and increased dangerous behaviours as a result. This will be increasingly important as modern work and social practices encourage people to increasingly use the phone while driving, and the technology within smart devices, and connectivity of these to the vehicle, increase. More research is needed to understand whether mindfulness-based interventions can reduce nomophobia, and thereby improve driving behaviours and reduce crash rates.     

Capturing the effects of texting on young drivers behaviour based on copula and Gaussian Mixture Models

This research effort aims to investigate the impact of texting on young drivers' behavior and safety based on data from driving simulator experiments, for different driving contexts, like motorways, urban and rural roads, during daytime and night, and for alternative weather conditions (‘clear sky’ and rain). The study offers a complete and comprehensive investigation of the effects of texting on driving behavior, able to provide evidence on policy-making. For the purposes of this study, a driving simulator experiment was carried out where 34 young participants drove predefined driving scenarios. Initially, multivariate copula analysis was used in order to explore statistical inferences among variables, especially since it retains a parametric specification for bivariate dependencies and allows testing of several parametric structures to characterize them. Secondly, alternative copula configurations were tested, which showed that texting and other road and environmental characteristics affect young drivers behavior and in particular more than one outcome can occur at the same time. Finally, Gaussian Mixture Modeling (GMM) was employed, demonstrating that the variables' pairs that presented the strongest correlations were lane departure and speed, as well as speed and reaction time. GMMs application showed that drivers using mobile phones who were involved in a collision presented a different driving behavior compared to the drivers who were occupied but were not involved in a collision.     

Nomophobia and self-reported smartphone use while driving: An investigation into whether nomophobia can increase the likelihood of illegal smartphone use while driving

In Australia, illegal smartphone use while driving is on the rise, increasing the likelihood drivers could be distracted and crash. Smartphones avail users a sense of belonging, connectedness, and access to information. As such, the sensation of being without one’s smartphone has developed into the prevalence of nomophobia, defined as the fear and anxiety associated with being without smartphone. The aim of the current study was to specifically examine the relationship between smartphone use while driving and nomophobia by 1) determining the types and frequency of illegal phone use while driving and, 2) exploring the relationship between nomophobia and illegal phone use while driving. The sample consisted of 2,774 Victorian smartphone users (47.0% male) with a valid driver’s licence. Driver’s nomophobia levels were measured using the Nomophobia Questionnaire (NMP-Q), while driver’s smartphone use was measured using an original scale developed by the authors. A binary logistic regression was conducted which showed that the longer average time spent per day on a smartphone and a lack of knowledge of the mobile phone road law were the strongest positive predictors of illegal use (OR = 1.32, 95% CI = 1.09–1.60; OR = 1.84, 95% CI = 1.48–2.28, respectively). However, only one nomophobia factor (i.e., access to information) significantly predicted illegal smartphone use (OR = 1.06, 95% CI = 1.04–1.09). Smartphone use is a complex and contextual behaviour, therefore, focusing on the fear of being without in dependency overlooks the nuances of the need to be with. This study offered several practical interventions that may mitigate illegal smartphone use and reduce the likelihood of crashes among Victorian road users.     

The function of information immediacy and smartphone usage

The current study used the delay discounting method to understand the need to respond to different communication mediums. In this method, participants were asked their preference between responding immediately for a smaller reward or after a delay for a larger reward. Experiment 1 asked participants their preference for responding to a text message, sticky note, and postcard. Participants indicated lower willingness in responding to the text message but did not have differing preferences between the other mediums. Experiment 2 sought to understand if the effect was related specifically to text messages or all instantaneous communication. Participants indicated their preference for responding to a text message, email, and voicemail while driving on a road trip. Participants indicated no differences in preference for responding to the message mediums. These results have implications for interpreting distracted driving research, specifically texting and driving, as the effect may apply to other communication mediums.     

Driver behaviour and traffic accident involvement among professional urban bus drivers in China

The present research aimed to investigate specific behaviors of professional urban bus drivers in China with the revised Driver Behavior Questionnaire (DBQ), and to define the relationships among various driving behaviors (errors, positives, inattention errors, violations), background information (age, years of driving experience, mobility, etc.), self-assessment, and traffic accident. To achieve such goals, the present research designed a four-dimensional DBQ with 20 items for professional urban bus drivers in China. The KMO coefficient of the whole scale was 0.835, and Bartlett’s test was statistically significant (p < 0.000), which demonstrated strong validity of the scale and should be suitable for factor analysis. The four loading factors accounted for 58.991%. In addition, the reliability and effectiveness of the present 20-item scales were measured. The coefficient of internal consistency-Cronbach’s alpha coefficient was 0.881 and the Cronbach’s Alpha Based on Standardized Items was 0.911. This showed that driving behavior scale of professional bus drivers in China was of high reliability and validity. The analysis showed that among the four factors, positive driving behaviors were significantly associated with errors, inattention errors and violations, respectively. Errors, inattention errors and violations correlated positively with each other. This verified that the correlation coefficient of each factor was medium and high, which indicated that the scale had good difference validity. The test content of the total scale was also highly consistent with the test content of each factor, which indicated that the revised scale had good standard related validity. According to the accident prediction model, the variables that significantly affected the occurrence of traffic accidents were daily driving time, positive driving behavior, SE2 (Driving safety), SE3 (Aberrant driver behaviors). The results showed that professional bus drivers often working overtime were most likely to have accidents. The probability of traffic accidents decreased by 53% for every unit of positive driving behavior frequency of professional bus drivers. The more they felt that they had the tendency of aberrant driving behavior, the more likely they were to have traffic accidents. To summary, the present research contributed to validating and improving the DBQ for professional urban drivers in China.     

Driving distraction at night: The impact of cell phone use on driving behaviors among young drivers

Currently, young drivers are more likely than other drivers to use cell phones while driving at night, which has become a major cause of road crashes. However, limited attention has been given to distracted nighttime driving. Therefore, the aim of this study was to explore the interaction effect of cell phone use and time of day (daytime and nighttime) on young drivers’ car-following performance. Forty-three young drivers engaged in a driving simulator experiment with a within-subject design that included three distractions (no distraction, talking and texting on a cell phone) and two times of day. This paper applied non-parametric tests to analyze the data and obtained the following results: (1) the standard deviation of lane position (SDLP) did not significantly differ at either time of day under no distraction, but it was significantly higher at night on straight roads and large-radius curves after introducing distractions. In addition, participants drove faster and gave less headway on small-radius curves under both distractions at night; (2) texting significantly increased the SDLP, while there was less lateral variation during the talking tasks than under no distraction on simple road sections; and (3) compared with the experienced drivers, the novice drivers drove faster during the talking tasks on small-radius curves, but there was no significant difference between groups during the texting tasks. These findings provide both theoretical and practical implications for related policy makers to enhance traffic safety.     

Relating mindfulness and self-control to harm to the self and to others

Aggression to others and harm to the self (self-harm) have both been associated with similar possible antecedents; however, literatures on aggression and self-harm are commonly separated. This web-based study (N = 241) aimed to explore the dynamics of self-reported mindfulness and self-control towards aggression and self-harm. As predicted, those who were more mindful and more self-controlled reported being less aggressive and self-harmless typically. Bootstrap analyses suggested that self-control mediated the link between mindfulness and general trait aggression, physical aggression, anger, hostility, and self-harm, but not verbal aggression. With the inclusion of self-control, the direct effect of mindfulness on trait aggression, anger, and hostility, but not on physical aggression and self-harm, remained significant. Self-control, therefore, may be a pertinent individual difference on the link between mindfulness and behaviours that are physically harmful to the self and to others.     

Examining the relationship between trait self-control and stress: Evidence on generalizability and outcome variability

Trait self-control has in several studies been found negatively linked to stress. These studies have, however, mostly relied on student and/or one-country samples. Study 1 investigated the generalizability of the relationship between trait self-control and stress through a four-country survey (N = 4097). The results showed consistently strong and negative relationships between trait self-control and stress across the four countries. Study 2 investigated the relationship between trait self-control and daily stress through a two-week diary study (N = 594; n_obs = 7880), showing that trait self-control was negatively related to daily stress and stress variability. Together, the two studies show that trait self-control’s negative link to stress generalizes beyond students and the United States.     

Screening out accident-prone Iranian drivers: Are their at-fault accidents related to driving behavior?

To provide a scientific background in road safety domain a better understanding of human risk factor is crucial. The aims of the present study were the following: (1) developing an accident prediction model for estimating the at-fault accidents of drivers (2) controlling for the regression-to-the-mean and screening out the accident-prone drivers (3) identification of significant behavioral predictors in at-fault accident occurrences and delving into the relationship between the aberrant driving behaviors and at-fault accidents of those identified as accident-prone. A questionnaire survey compiling various measures of personality type, aberrant driving behavior, demographic and accident history information of 1762 Iranian drivers was conducted in which 1375 male and 387 female participants were of the average age of 35.6 (S.D. = 11.987). To analyze the obtained data, the generalized linear modeling (GLM) approach was taken resulting in four models with various independent variables. The results indicated that age, gender, education level, years of active driving, and especially exposure had an effect on drivers’ at-fault accidents while there was no discernible effect from income level, personality type and area of residence. In the screening procedure, 715 drivers were identified as accident-prone. Behavioral comparison analyses indicated that the lapses, errors, ordinary and aggressive violations are different for the accident-prone drivers. A comparison between the accident-prone and non-accident-prone drivers revealed that the ordinary violations have considerably higher effect than the others on at-fault accidents. Implications of the results are discussed with regard to insurance policies and education interventions.     

The factors underlying the decision to text while driving

Using the Theory of Planned Behaviour (TPB), this study looked at the motivations and reasons behind the behaviour of texting while driving. Following an elicitation study, 150 participants completed a questionnaire measuring self-efficacy and moral norms in addition to traditional TPB variables. Texting while driving was found to be a common behaviour although prevalence varied between age groups. While the youngest age group were more likely to have ever sent a text message while driving, those aged 35–44 years old were most likely to have read a message while driving and to intend to text while driving in the future. Moral norms had the strongest significant correlation with intentions to text while driving. Similar to past research the traditional TPB variables explained significant variance in intentions to perform the behaviour. To be fully effective, future campaigns and interventions to reduce the behaviour are advised to focus on the moral aspect of the behaviour and the beliefs that it saves time and prevents boredom. The setting of campaigns or interventions and the mode of delivery should also be considered. Efforts to deter the behaviour should be aimed at those of all ages and not just younger drivers.     

Analyzing driver's response to the yellow onset at signalized intersections

Intersections are critical points within the highway system at which the risk of crashes increases. This study seeks to better understand drivers’ behavior at an intersection by examining the relationship between their observed driving behavior, psychological attributes and decision to proceed through an intersection. A driving simulator and self-report questionnaire were used to understand driver decision-making at the onset of the yellow phase across several signalized intersections. The simulator measured driving outcomes such as speed, braking, and throttle as drivers cross through four increasingly difficult intersections. The questionnaires measured demographics, psychological traits including mindfulness and impulsiveness along with self-reported driving behaviors. A total of 102 participants completed the questionnaire as well as the driving simulator experiment. Hierarchical clustering served to classify drivers into four groups on the basis of their observed driving in the simulator: the safest drivers, safe drivers, speed demons, and aggressive drivers. These driving styles moderated the relationship between the drivers’ psychological traits and their decision to stop or proceed at each intersection. Results showed that mindfulness was highly related to the safest drivers’ decision to stop at the first intersection, while impulsiveness and anxiety were related to the speed demons’ decision to stop at the third intersection. These findings lay a strong foundation for developing progressive educational campaigns incorporating driver psychology in their methodology. Findings also provide support for research linking driving performance and psychological traits with implications for intersection design.     

Mindful Mates: A Pilot Study of the Relational Effects of Mindfulness‐Based Stress Reduction on Participants and Their Partners

Very little is currently known about how increases in dispositional mindfulness through mindfulness training affect the quality of participants’ romantic relationships, and no previous studies have examined how increases in specific facets of mindfulness differentially contribute to relationship health. Additionally, even less is known about how an individual's development of mindfulness skills affects the relationship satisfaction of his or her romantic partner. Thus, the purpose of this pilot study was to examine associations between changes in facets of mindfulness and relationship satisfaction among participants enrolled in a Mindfulness‐Based Stress Reduction (MBSR) course and their nonenrolled romantic partners. Twenty MBSR participants and their nonenrolled partners (n = 40) completed measures of mindfulness and relationship satisfaction pre‐ and post‐enrolled partners’ completion of an MBSR course. Results indicated that enrolled participants significantly improved on all facets of mindfulness and relationship satisfaction, while nonenrolled partners did not significantly increase on any facet of mindfulness or relationship satisfaction. Moreover, enrolled participants’ increases in Acting with Awareness were positively associated with increases in their own and their nonenrolled partners’ relationship satisfaction, whereas increases in enrolled participants’ Nonreactivity were positively associated with increases in their nonenrolled partners’ (but not their own) relationship satisfaction. These results suggest that increasing levels of mindfulness (particularly specific aspects of mindfulness) may have positive effects on couples’ relationship satisfaction and highlight mindfulness training as a promising tool for education and intervention efforts aimed at promoting relational health.
