Effect of decals on teen compliance with and enforcement of driving restrictions

描述(由申请人提供)：分级驾驶执照(GDL)法律显著减轻了青少年车祸的负担，部分原因是限制了新获得执照的青少年司机(即见习司机)从事高风险驾驶行为。然而，它们的有效性受到以下挑战的限制：(1)青少年司机遵守GDL限制的意愿，以及(2)执法部门执行这些限制的能力，因为没有 很明显可以用来辨认准司机的车辆。新泽西州最近在他们的GDL法律中实施了全国首个贴花条款，要求见习司机在开车时在汽车上贴上高度可见的贴花。这项创新的法律旨在促进GDL限制的执行，并增加见习司机避免高风险驾驶行为的可能性，从而降低他们的撞车风险。尽管其他几个国家早就要求贴花，但还没有对贴花规定进行评估，部分原因是缺乏适当的研究方法。这项研究旨在评估新泽西州的贴花条款对见习司机遵守四项GDL限制(同行乘客限制、夜间宵禁、禁止使用电子设备和要求使用安全带)以及警察执行这些限制的影响。此外，这项研究将确定遵守当前新泽西州GDL限制的预测因素，以确定青少年司机亚群参与危险驾驶行为的高风险。为了克服方法学上的挑战，我们将采用诱导暴露技术的新应用，这是一种交通安全研究特有的经过验证的方法。特别是，这项研究将借用该技术的主要原则，即两车相撞事故中的非负责任司机是由负责任的司机从道路使用者群体中随机选择的，因此是道路使用者群体中合理具有代表性的样本，以基于总体对新泽西州见习司机的遵从性进行法律前和法律后的估计。为了解决特定的目标，我们将分析一个包含新泽西州撞车和驾驶执照信息的链接数据库。新泽西州撞车报告中的数据将被用来确定在撞车事故中遵守每一项限制的非负责任的见习司机的比例，而与GDL相关的引用数据将被用来估计不遵守见习司机的GDL执法情况。这项评估对美国GDL贴花法律的未来至关重要，因为有几个州正在等待结果，同时考虑实施类似的条款。此外，这项研究将有助于建立贴花规定的科学证据基础--这是一种有争议的、但可能是重要的政策干预措施，以加强GDL。最后，这项研究将通过为研究人员提供一种创新的方法来推进年轻司机研究领域：(1)评估政策层面干预对驾驶行为的影响；(2)估计不同年轻司机亚组中参与难以捕获的危险行为(例如，夜间驾驶)的程度；以及(3)确定年轻司机的高危亚组作为未来干预的目标。虽然渐进式驾驶执照(GDL)法大大减轻了青少年机动车撞车事故的负担，但它们对公共健康的潜在影响取决于努力加强青少年对GDL限制(乘客限制、宵禁、安全带使用、手机限制)的遵守和警察执法。这项研究将评估新泽西州的创新努力是否会增加青少年司机对GDL限制的遵从性和执法性。GDL法律要求青少年司机在车辆牌照上展示贴花，以便于警察识别自己。结果将为新泽西州法律的未来改进提供富有成效的信息，指导美国其他州考虑类似法律的政策制定者的决策，并为贴花法律的有效性提供亟需的科学证据。 与公共健康相关：尽管渐进式驾驶执照(GDL)法大大减轻了青少年机动车撞车事故的负担，但它们对公共健康的潜在影响取决于努力加强青少年对GDL限制(乘客限制、宵禁、安全带使用、手机限制)的遵守和警察执法。这项研究将评估新泽西州的创新努力是否会增加青少年司机对GDL限制的遵从性和执法性。GDL法律要求青少年司机在车辆牌照上显示贴花，以便于警察识别自己。结果将为新泽西州法律的未来完善提供富有成效的信息，指导美国其他州考虑类似法律的政策制定者的决策，并为贴花法律的有效性提供亟需的科学证据。

DESCRIPTION (provided by applicant): Graduated Driver Licensing (GDL) laws have significantly reduced the burden of teen crashes, in part by restricting newly-licensed teen drivers (i.e., probationary drivers) from engaging in high-risk driving behaviors. However, their effectiveness has been limited by challenges with: (1) teen drivers' willingness to comply with GDL restrictions and (2) law enforcement's ability to enforce these restrictions, given there is no obvious way to identify a probationary driver's vehicle. New Jersey (NJ) recently implemented the first-in-the-nation decal provision into their GDL law, requiring probationary drivers to disply highly-visible decals on their cars while driving. This innovative law is designed to facilitate enforcement of GDL restrictions and increase the likelihood that probationary drivers avoid high-risk driving behaviors, thereby reducing their crash risk. Although several other countries have long required decals, decal provisions have not yet been evaluated, in part because of a lack of adequate research methods. This study aims to evaluate the effect of NJ's decal provision on probationary drivers' compliance with four GDL restrictions (peer passengers limits, nighttime curfew, ban on use of electronic equipment, and required seat belt use) and police officers' enforcement of these restrictions. Additionally, the study will determine predictors of compliance with current NJ GDL restrictions in order to identify adolescent driver subgroups at high-risk of engagement in risky driving behaviors. To overcome methodological challenges, we will employ a novel application of the induced exposure technique, a validated method unique to traffic safety research. In particular, this study will borrow the technique's main principle, that non-responsible drivers in two-car crashes are randomly selected by responsible drivers from the population of road users and thus are a reasonably representative sample of the road user population, to make population- based pre- and post-law estimates of compliance among NJ probationary drivers. To address specific aims, we will analyze a linked database containing NJ crash and driver licensing information. Data from NJ's crash report will be used to identify the proportion of non-responsible probationary drivers in crashes who were complying with each restriction, while data on GDL-related citations will be used to estimate GDL enforcement among non-complying probationary drivers. This evaluation is critical to the future of GDL decal laws in the U.S., as several states are awaiting results as they consider implementing similar provisions. Further, this study will contribute to building the scientific evidence base for decal provisions - a controversial, but potentially important policy intervention to enhance GDL. Finally, this study will advance the field of young driver research by providing researchers with an innovative method to: (1) evaluate the effects of policy-level interventions on driving behavior;(2) estimate the extent of engagement in hard-to-capture risky behaviors (e.g., nighttime driving) among various young driver subgroups; and (3) identify high-risk subgroups of young drivers to target for future interventions. Although Graduated Driver Licensing (GDL) laws have significantly reduced the burden of teen motor vehicle crashes, their potential to have an even greater impact on public health hinges on efforts to enhance teen compliance with and police enforcement of GDL restrictions (passenger limit, curfew, seat belt use, cell phone restriction). This study will evaluate whether New Jersey's innovative effort to do so - a GDL law requiring novice teen drivers to display a decal on their vehicle's license plate to make themselves easily identifiable to police - increases teen drivers' compliance with and officers' enforcement of GDL restrictions. Results will productively inform future refinements of New Jersey's law, guide decisions of policymakers in other U.S. states considering similar laws, and provide much-needed scientific evidence as to the effectiveness of decal laws.
