To examine the crash trends of younger novice and older novice/returning motorcycle riders.
We used a linked database of North Carolina crash and licensing data from 1991 through 2018 that included 103,142 younger novice and 98,540 older novice/returning motorcycle riders. We examined the percent of riders who crashed each month after obtaining a motorcycle license.
Crash rates peak for both younger novice and older novice/returning motorcycle riders immediately after licensure. Crash rates decline rapidly, and the rate of decrease resembles a power function. The improvement rate (IR) for younger novice riders is 0.42; that is, the crash rate for younger novices declines by approximately 42% as experience doubles.
The crash curve for novice motorcyclists is similar to that of novice car drivers and is consistent with a learning process.
The crash trends of novice motorcycle riders indicate that current training, licensing, and educational efforts are not adequately preparing new riders. Additional efforts to develop more effective training, and research to inform a well-calibrated graduated licensing process for new riders are needed.
研究年轻新手和年长新手/复驶摩托车驾驶员的撞车趋势。
我们使用了北卡罗来纳州 1991 年至 2018 年的碰撞和许可数据库的链接数据库，其中包括 103142 名年轻新手和 98540 名年长新手/复驶摩托车驾驶员。我们检查了每个月获得摩托车驾照后发生撞车事故的骑手比例。
年轻新手和年长新手/复驶摩托车驾驶员的撞车率在获得驾照后立即达到峰值。撞车率迅速下降，下降速度类似于幂函数。年轻新手的改进率（IR）为 0.42；也就是说，随着经验的翻倍，年轻新手的撞车率下降了约 42%。
新手摩托车驾驶员的撞车曲线与新手汽车驾驶员的撞车曲线相似，符合学习过程。
新手摩托车驾驶员的撞车趋势表明，目前的培训、许可和教育工作并没有充分准备新驾驶员。需要进一步努力开发更有效的培训，并进行研究，为新驾驶员提供校准良好的分级许可流程。
