Tennessee's Novice Driver Safety Project: a program to increase parental involvement

Translational Research in Child and Adolescent Transportation Safety

Motor vehicle crash (MVC)–related injury is the leading cause of death among youths age 1 to 19 years. Advances in MVC and injury prevention depend on interrelated combinations of technology, policy, and education, and research on these topics can inform policy and lead to improvement in safety. This article presents two examples of translational research in transportation injury prevention. In the first example of child passenger protection, the authors describe a program of research designed to reduce the gap between the theoretical and practical effectiveness of safety methods. In the second example of novice teen drivers, the authors examine translational research related to two complementary approaches to reducing the exposure of novice teen drivers to high-risk driving conditions—graduated driver licensing policy and parental management of novice teen drivers. The examples suggest the utility of systematic programs of research designed to improve the translation into practice of MVC and injury prevention technology and policy.

Effectiveness of Parent-Focused Interventions to Increase Teen Driver Safety: A Critical Review

PURPOSE

We critically reviewed recent parent-directed teen driving interventions to summarize their success in meeting stated goals; identify promising intervention components and knowledge gaps; aid in the selection, adaptation, and dissemination of effective interventions; and guide future research efforts.

METHODS

We focused on interventions that included a direct parent component, explicitly stated outcomes related to the teen and/or their parents, were evaluated for parent or teen outcomes, targeted drivers younger than the age of 21 years, and had at least one evaluation study published since 1990 and in English. We conducted a comprehensive systematic search of 26 online databases between November 2013 and January 2014 and identified 34 articles representing 18 interventions.

RESULTS

Several interventions-in particular, those that had an active engagement component, incorporated an in-vehicle data recorder system, and had a strong conceptual approach-show promise in improving parental supervisory behaviors during the learner and early independent phases, increasing teen driver skill acquisition, and reducing teens' risky driving behaviors.

CONCLUSIONS

We identify essential characteristics of effective parent-involved teen driving interventions and their evaluation studies, propose a comprehensive and multitiered approach to intervention, and discuss several research areas and overarching issues for consideration.

The effect of family climate on risky driving of young novices: the moderating role of attitude and locus of control

The aim of the study was to examine the relative importance of young novice drivers' family climate on their driving behavior. A sample of young novice drivers (N=171) between the age of 17 and 24, who held their permanent (or temporary) driver's license for no longer than one year, participated. The questionnaire included items related to the participants' family climate, 3 socio-cognitive determinants (i.e., attitude, locus of control and social norm), and risky driving behaviors. We expected both family climate and the socio-cognitive determinants to exert a direct effect on risky driving. Furthermore we hypothesized that the socio-cognitive determinants would moderate the impact of family climate on risky driving. The results showed that the effect of family climate on risky driving only originated from one single factor (i.e., noncommitment). Besides that, the results confirmed the importance of the three socio-cognitive determinants to the degree that attitude, locus of control, and social norm significantly predicted the self-reported risky driving. In line of what we hypothesized, attitude moderated the relationship between noncommitment and risky driving. Lastly, we found an unexpected three-way interaction which indicated that locus of control moderated the relation between noncommitment and risky driving only when young drivers' attitude was risk-supportive. We recommend scholars and practitioners to take into account the interaction between external sources of influence (such as an individual's family climate) and more personally oriented dispositions (such as an individual's attitude, social norm and locus of control) when trying to explain and change young novices' risky driving.

Parents' attitudes about Connecticut's required driver orientation course for parents

OBJECTIVE

Connecticut is the first state to require a parent of 16- and 17-year-olds to complete a 2-h training course prior to licensure. The objective of the study was to determine parents' evaluations of the course, what they learned, and how they said they used this information.

METHODS

A telephone survey was conducted of 300 parents of initial license holders who had taken the course in its first year.

RESULTS

Most parents approved of the course requirement, liked the way the course was delivered, and learned new information that they said they used to guide their teen through the licensing process. Eighty-five percent rated the course as excellent (41%) or good (44%). Parents reported that most relevant topics were covered, with the exception of vehicle choice. The majority of parents knew essential details of Connecticut's nighttime and passenger restrictions, although 35 percent lacked knowledge of the passenger restriction.

CONCLUSIONS

The course was well received and serves its purpose of providing parents with important knowledge they found useful. Results suggest that the course has beneficial effects, although the extent to which teen driving behavior and crash involvement is affected by the parent training is not known.

Parenting and the young driver problem

Crash rates increase sharply at the age at which teenagers begin to drive and remain elevated relative to adult levels until drivers are well into their twenties. Parents have important roles to play in managing the risk for teenage drivers before and after licensure. Parents can be involved in their teenagers' driving, allowing them to test for permit and licensure, supervising practice driving, providing access to a vehicle, and setting and enforcing limits on driving privileges after licensure. However, the management practices of many parents may not be sufficient to provide safety effects. The literature indicates that the two most important decisions parents can make to reduce teenagers' driving risk are to delay licensure and impose limits on high-risk driving conditions (such as driving at night and with teenage passengers) during the first year of licensure. Two intervention programs have been shown to increase parental limit setting as a means of reducing risky driving behaviors and improving driving performance among novice teenage drivers. This article describes the contexts of and opportunities for parental involvement in teenage driving and the effectiveness of interventions to increase and improve parental management of young drivers.

Improving graduated driver licensing systems: a conceptual approach and its implications

Graduated driver licensing (GDL) is a concept for how to transform non-drivers into reasonably safe drivers while minimizing the risks as they learn. Several state GDL programs can be improved by moving their structures closer to an adequate implementation of that concept. The learner stage of a GDL system needs to be long enough for beginners to obtain a thorough introduction to the vagaries of driving. The second or intermediate stage needs to effectively limit exposure to known high risk conditions as novices adapt to being fully in charge of the vehicle. The benefits of GDL to date are due almost entirely to the risk-reducing conditions it implements. To improve the functioning of GDL will probably require a better understanding of teen driving than we presently have. The likelihood of further gains will be enhanced by efforts to learn more about the actual causes of teen crashes, the nature and type of teen driver exposures, and what parents do with their teens during the supervised driving stage of GDL. Without a better understanding of these, and other, phenomena it will be difficult to further reduce crashes among young beginning drivers, whether through GDL enhancements or with other approaches.

Parent involvement in novice teen driving: rationale, evidence of effects, and potential for enhancing graduated driver licensing effectiveness

Motor-vehicle crash rates are highly elevated immediately after licensure and then decline gradually over a period of years. Young age, risk taking, and inexperience contribute to the problem, but inexperience is particularly important early on. Driving is like other complex, skilled behaviors in which subtle improvements in perception and judgment develop gradually over a period of years. After all, safe driving is more a matter of attention and perception than physical management of the vehicle. Inexperience is particularly linked to driving performance and safety outcomes under certain driving conditions, with driving at night and with teen passengers as the most important cases. Surprisingly, driving outcomes do not appear to be affected by the pre-license training or supervised practice driving. Given the limits of training, safety effects can best be achieved by countermeasures that delay licensure or limit novice teen driving under high risk driving conditions while novices gain experience and develop safety competence. The two complementary approaches of Graduated Driver Licensing policies and parent management have been shown to provide safety effects by limiting the driving conditions of novice teenagers.

Young driver risk factors: successful and unsuccessful approaches for dealing with them and an agenda for the future

The extent to which various interventions to deal with the young driver crash problem have worked are discussed, and promising interventions that should be tried are identified. Traditional forms of driver licensing and driver education have not worked. Graduated licensing reduces the problem and existing laws need to be strengthened. Programs involving parents and police have shown some potential to increase compliance with graduated licensing restrictions. Insurer discount programs also have potential. In other public health areas, comprehensive programs have worked better than those based on single components. There are continuing efforts to develop new driver education and training programs and methods of delivery that can combine with graduated licensing and contribute to reductions in the young driver problem. The most promising intervention strategy is likely to be a coordinated community based program in states with strong graduated licensing laws as a foundation, involving modern education and training techniques, insurance discount programs, and well publicized enforcement and education programs featuring parents and police in combination, with as much input and participation as possible from the target group of young drivers.

Parental supervision of teenage drivers in a graduated licensing system

OBJECTIVES

Most states now have lengthy learner periods for young, beginning drivers as part of their graduated driver licensing (GDL) systems. Although parents play a vital role during the learner stage of GDL by supervising driving practice, virtually nothing is known about the nature and quality of parental supervision. The objectives of this study were to investigate parents' supervisory behavior and parent-teen relationships during the learner stage of graduated licensing and to evaluate two approaches for assisting parents in supervising their teenager's early driving experience.

METHODS

Families of teenagers applying for a learner permit received either a booklet describing highly structured practice sessions for beginning drivers, a series of "tip sheets" offering more generalized guidance, or no special materials. Questionnaires were sent separately to parents and teenagers three to six months after teenagers obtained their permit.

RESULTS

Of 1,190 participating families, 653 parents (55%) and 609 teenagers (51%) responded. Both parents and teenagers perceived parents as supportive and helpful during driving sessions. Parents often demonstrated positive behaviors, such as complimenting their teenager and pointing out possible hazards; they also exhibited less desirable behaviors, such as raising their voice, but these were less frequent. A majority of parents (71%) and teenagers (52%) reported that they enjoyed spending this time together. About four months after obtaining a permit, most parents believed their teenager did not yet have enough experience and was not ready to drive unsupervised. Although the reported behaviors are encouraging, within-family agreement was low on most items. Finally, efforts to assist parents proved unsuccessful. Although parents thought the booklet and tip sheets were helpful, most used these materials only in a general way.

CONCLUSIONS

The extended learning experience required by GDL programs is a positive experience for many families. However, finding a method for helping parents achieve maximum benefits during this process will be challenging. The results also suggest that current requirements in the learner phase of most state GDL systems (six months; 30-50 hours) may be inadequate to ensure that teenagers obtain a sufficient amount of experience to begin driving safely on their own.

Parent involvement in novice teen driving: a review of the literature

Motor vehicle crashes remain elevated among novice teen drivers for at least several years after licensure. Licensing policies and driver education are the two primary countermeasures employed to decrease young driver crash risks. Graduated driver licensing policies have proved to be effective in reducing crash rates where evaluated. Driver education is an essential part of teaching teens the rules of the road and operating a vehicle, but requires few hours of professional driver training, relying mainly on parents to provide most of the supervised practice driving teens obtain before independent driving licensure. The few studies that have been conducted to increase parent supervised practice driving have not shown positive results. Moreover, it is unclear that increases in practice would improve independent driving safety. Recent research has shown that parent management of the early independent driving experience of novice teens improves safety outcomes, and other research has shown that it is possible to increase parent management practices. This paper provides a review of the literature on parent involvement in supervised practice and independent driving, and efforts to increase parental management.

Graduated driver licensing research in 2004 and 2005

This is the second update of research on graduated driver licensing (GDL) and teenage drivers. It briefly summarizes research in progress and research published since the January 2004 update (Hedlund, J. & Compton, R. [2004]. Graduated driver licensing research in 2003 and beyond. Journal of Safety Research 35(1), 5-11). Research has been very active, especially on teenage driver risk factors, GDL program evaluations, the role of parents in managing and training their teenage drivers, and driver education. Results have strengthened the case for GDL, for nighttime and passenger restrictions, and for extended supervised driving practice.
