As drivers age, their risk of being involved in a car collision decreases. The present study investigated if this trend is due, in part, to some risky drivers having a collision early in their driving lives and subsequently reducing their risky driving after that negative experience. Accelerometers and video cameras were installed in the vehicles of 16- to 17-year-old drivers ( N = 254), allowing coders to measure the number of g-force events (i.e., events in which a threshold acceleration level was exceeded) per 1,000 miles and the number of collisions. Among the 41 participants who experienced a severe collision, the rate of g-force events dropped significantly in the 1st month after the collision, remained unchanged for the 2nd month, and increased significantly in the 3rd month. There were no changes in the rate of g-force events at comparable time points for the drivers not involved in a collision. Being involved in a collision led to a decrease in risky driving, but this may have been a temporary effect.
随着驾驶员年龄的增长,他们卷入汽车碰撞事故的风险会降低。本研究调查了这种趋势是否部分归因于一些危险驾驶员在其驾驶生涯早期发生了碰撞事故,随后在经历了那次负面事件后减少了危险驾驶行为。加速度计和摄像机被安装在16至17岁驾驶员(N = 254)的车辆中,使编码人员能够测量每1000英里的重力加速度事件数量(即超过阈值加速度水平的事件)以及碰撞次数。在经历了严重碰撞的41名参与者中,重力加速度事件发生率在碰撞后的第1个月显著下降,第2个月保持不变,第3个月显著增加。未发生碰撞的驾驶员在可比时间点的重力加速度事件发生率没有变化。卷入碰撞事故导致危险驾驶行为减少,但这可能只是一种暂时的影响。
