The impact of young drivers' motor vehicle crashes (MVC) is substantial, with young drivers constituting only 14% of the US population, but contributing to 30% of all fatal and nonfatal injuries due to MVCs and 35% ($25 billion) of the all medical and lost productivity costs. The current best-practice policy approach, Graduated Driver Licensing (GDL) programs, are effective primarily by delaying licensure and restricting crash opportunity. There is a critical need for interventions that target families to complement GDL. Consequently, we will determine if a comprehensive parent-teen intervention, the Drivingly Program, reduces teens' risk for a police-reported MVC in the first 12 months of licensure. Drivingly is based on strong preliminary data and targets multiple risk and protective factors by delivering intervention content to teens, and their parents, at the learner and early independent licensing phases.
Eligible participants are aged 16-17.33 years of age, have a learner's permit in Pennsylvania, have practiced no more than 10 h, and have at least one parent/caregiver supervising. Participants are recruited from the general community and through the Children's Hospital of Philadelphia's Recruitment Enhancement Core. Teen-parent dyads are randomized 1:1 to Drivingly or usual practice control group. Drivingly participants receive access to an online curriculum which has 16 lessons for parents and 13 for teens and an online logbook; website usage is tracked. Parents receive two, brief, psychoeducational sessions with a trained health coach and teens receive an on-road driving intervention and feedback session after 4.5 months in the study and access to DriverZed, the AAA Foundation's online hazard training program. Teens complete surveys at baseline, 3 months post-baseline, at licensure, 3months post-licensure, 6 months post-licensure, and 12 months post-licensure. Parents complete surveys at baseline, 3 months post-baseline, and at teen licensure. The primary end-point is police-reported MVCs within the first 12 months of licensure; crash data are provided by the Pennsylvania Department of Transportation.
Most evaluations of teen driver safety programs have significant methodological limitations including lack of random assignment, insufficient statistical power, and reliance on self-reported MVCs instead of police reports. Results will identify pragmatic and sustainable solutions for MVC prevention in adolescence.

年轻驾驶员发生机动车碰撞（MVC）的影响巨大，尽管年轻驾驶员仅占美国总人口的 14%，但他们却导致了 30%的 MVC 导致的所有致命和非致命伤害，以及 35%（250 亿美元）的所有医疗和生产力损失。目前最好的实践政策方法是分级驾驶执照（GDL）计划，其主要通过延迟许可和限制碰撞机会来发挥作用。因此，我们将确定一项全面的家长-青少年干预措施，即 Drivingly 计划，是否可以降低青少年在获得执照后的 12 个月内发生警方报告的 MVC 的风险。Drivingly 计划基于强有力的初步数据，通过向青少年及其父母在学习阶段和早期独立驾驶阶段提供干预内容，针对多个风险和保护因素进行干预。
合格的参与者年龄在 16-17.33 岁之间，在宾夕法尼亚州拥有学习许可证，实际练习时间不超过 10 小时，至少有一位父母/照顾者监督。参与者从普通社区和费城儿童医院的增强招募核心招募。青少年-父母对子随机分为 Drivingly 组或常规实践对照组，每组 1：1。Drivingly 组参与者可以访问在线课程，其中包括 16 节针对父母的课程和 13 节针对青少年的课程以及在线日志；网站使用情况被跟踪。父母接受两次简短的心理教育课程，由训练有素的健康教练进行指导，青少年在研究进行 4.5 个月后接受一次路考驾驶干预和反馈，并可以访问 AAA 基金会的在线危险培训计划 DriverZed。青少年在基线、基线后 3 个月、获得执照时、获得执照后 3 个月、获得执照后 6 个月和获得执照后 12 个月进行调查。父母在基线、基线后 3 个月和青少年获得执照时进行调查。主要终点是在获得执照后的 12 个月内警方报告的 MVC；碰撞数据由宾夕法尼亚州交通部提供。
大多数青少年驾驶员安全计划的评估都存在重大方法学限制，包括缺乏随机分组、统计能力不足以及依赖自我报告的 MVC 而不是警方报告。研究结果将确定青少年期 MVC 预防的实用和可持续解决方案。
