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.

年轻司机卷入碰撞后会变得更安全吗？

随着驾驶员年龄的增长，他们卷入汽车碰撞的风险会降低。本研究调查了这种趋势是否部分是由于一些危险的驾驶员在他们驾驶生活的早期发生碰撞，随后在经历了负面经历后减少了他们的危险驾驶。加速度计和摄像机安装在 16 至 17 岁的司机（N = 254）的车辆中，允许编码员测量 g 力事件（即超过阈值加速度水平的事件）的数量。 1,000 英里和碰撞次数。在经历过严重碰撞的41名参与者中，碰撞后第1个月g力事件发生率显着下降，第2个月保持不变，第3个月显着增加。对于未参与碰撞的驾驶员，在可比较的时间点，g 力事件的发生率没有变化。卷入碰撞导致危险驾驶减少，但这可能是暂时的。
