PREVENTION OF MOTOR VEHICLE CRASHES AMONG YOUNG DRIVERS

青少年驾驶在前6个月和1000英里的驾驶中是特别危险的，不管在获得执照之前有多少监督练习驾驶。建议父母对初学驾驶的青少年的驾驶特权施加限制，在获得驾照的第一年，那时青少年还在学习驾驶。父母的限制与更少的危险驾驶和更少的违规和撞车有关。检查点计划包括有说服力的信息和材料，旨在鼓励父母采用检查点父母-青少年驾驶协议，并限制新手青少年驾驶员的高风险驾驶特权。先前评估检查点计划的随机试验，在一项研究中获得许可，在另一项研究中获得许可，显示了显著的治疗组对父母限制设置，青少年危险驾驶和违规行为的影响。

Teen driving is particularly dangerous the first 6 months and 1,000 miles of driving, regardless of the amount of supervised practice driving prior to licensure. Parent-imposed limits on novice teen driving privileges are recommended for the first year of licensure, when teens are still learning to drive. Parent limits are associated with less risky driving and fewer violations and crashes. The Checkpoints Program consists of persuasive messages and materials designed to encourage parents to adopt the Checkpoints Parent-Teen Driving Agreement and to limit higher-risk driving privileges among novice teenage drivers. Previous randomized trials evaluating the Checkpoints Program, delivered at permit in one study and licensure in another, have shown significant treatment group effects on parent limit setting, teen risky driving, and violations. The purpose of the current study is to determine the relative effectiveness of the Checkpoints Program when delivered at permit, license, or at both permit and license. The study is being conducted in Rhode Island, where 1,000 parent-teen pairs have been recruited at the time a teen receives a driving permit or provisional license. These pairs have been randomized to the comparison group or to the experimental Checkpoints Program groups (at permit, at licensure, or at permit and licensure). Study participants complete surveys at recruitment, and one month and six months after provisional licensure.
