Fatal crash risk is higher at night for all drivers, but especially for young, inexperienced drivers (1). To help address the increased crash risk for beginner teen drivers, 49 states and the District of Columbia include a night driving restriction (NDR) in their Graduated Driver Licensing (GDL) system. NDRs have been shown to reduce crashes among newly licensed teens, with higher reductions associated with NDRs starting at 10:00 p.m. or earlier (2-3). However, in 23 states and the District of Columbia, NDRs begin at 12:00 a.m. or later, times when most teen drivers subject to GDL are not driving. CDC analyzed 2009-2014 national and state-level data from the Fatality Analysis Reporting System (FARS) to determine the proportion of drivers aged 16 or 17 years involved in fatal crashes who crashed at night (9:00 p.m.-5:59 a.m.) and the proportion of these drivers who crashed before 12:00 a.m. Nationwide, among 6,104 drivers aged 16 or 17 years involved in fatal crashes during 2009-2014, 1,865 (31%) were involved in night crashes. Among drivers involved in night crashes, 1,054 (57%) crashed before 12:00 a.m. State-level analyses revealed an approximately twofold variation among states in both the proportions of drivers aged 16 or 17 years involved in fatal crashes that occurred at night and the proportions of night fatal crash involvements that occurred before 12:00 a.m. Because nearly all of the night driving trips taken by drivers aged 16 or 17 years end before 12:00 a.m., NDRs beginning at 12:00 a.m. or later provide minimal protection. States could consider updating their NDR coverage to include earlier nighttime hours. This descriptive report summarizes the characteristics of NDRs, estimates the extent to which drivers aged 16 or 17 years drive at night, and describes their involvement in fatal nighttime crashes during 2009-2014. The effects of NDRs on crashes were not evaluated because of the small state-level sample sizes during the 6-year study period.
所有司机夜间发生致命事故的风险更高,但尤其对于年轻、缺乏经验的司机来说更是如此(1)。为了帮助减少新手青少年司机的事故风险,49 个州和哥伦比亚特区在其分级驾照系统中包含夜间驾驶限制(NDR)。NDR 已被证明可以减少新获得驾照的青少年的事故,与夜间驾驶限制(NDR)开始时间为晚上 10 点或更早的情况相比,NDR 降低的幅度更高(2-3)。然而,在 23 个州和哥伦比亚特区,NDR 开始于凌晨 12 点或更晚,此时大多数受 GDL 约束的青少年司机都没有开车。CDC 分析了 2009-2014 年来自全国和州层面的 FARS 数据,以确定涉及致命事故的 16 或 17 岁司机中夜间(晚上 9 点至凌晨 5 点 59 分)发生事故的比例,以及这些司机中在凌晨 12 点之前发生事故的比例。在全国范围内,在 2009-2014 年期间,6104 名 16 或 17 岁的司机发生致命事故,其中 1865 人(31%)涉及夜间事故。在涉及夜间事故的司机中,有 1054 人(57%)在凌晨 12 点之前发生事故。州级分析显示,在涉及致命事故的 16 或 17 岁司机中,夜间发生事故的比例以及夜间致命事故发生在凌晨 12 点之前的比例,各州之间存在大约两倍的差异。由于 16 或 17 岁的司机夜间行驶的几乎所有行程都在凌晨 12 点之前结束,因此夜间驾驶限制(NDR)开始于凌晨 12 点或更晚,对夜间驾驶的保护作用不大。各州可以考虑更新夜间驾驶限制(NDR)的覆盖范围,以纳入更早的夜间时间。本报告总结了夜间驾驶限制(NDR)的特点,估计了 16 或 17 岁的司机夜间行驶的程度,并描述了他们在 2009-2014 年期间涉及致命夜间事故的情况。由于在 6 年的研究期间,州级样本量较小,因此没有评估夜间驾驶限制(NDR)对事故的影响。
