Driving under the influence (DUI) increases the probability of motor-vehicle collisions, especially for motorcycles with less protections. This study aimed to identify commonalities and differences between criminally DUI offenses (i.e., with a blood alcohol concentration (BAC) of 80 mg/dL or higher) committed by motorcyclists and car drivers.
A total of 10,457 motorcycle DUIs and 8,402 car DUIs were compared using a series of logistic regression models, using data extracted from the documents of adjudication decisions by the courts of Jiangsu, China.
The results revealed that offenders from the high-BAC group (i.e., 200 mg/dL or higher) accounted for more than 20% of the total DUI offenses, and were more likely to be involved in a crash and punished with a longer detention. Motorcyclists had a higher likelihood of crash involvement, and were also more likely to be responsible for single-vehicle crashes associated with higher odds of injury sustained, compared to alcohol-impaired car drivers. In the verdict, motorcycle offenders were more likely to receive a less severe penalty.
Interventions are clearly required to focus on reducing in the high-BAC group of offenders. For alcohol-impaired motorcyclists, their risks of crash and injury against BAC climb more steeply than the risks for car drivers. The factors including frequent occurrences, uncertainty of detection, and short-term sentences may weaken the deterrence effect of the criminalization of motorcycle DUI. Practical Applications: The traffic-related adjudication data support traffic safety analysis. Strategies such as combating motorcycle violations (e.g., unlicensed operators or driving unsafe vehicles), undertaking education and awareness campaigns, are expected for DUI prevention.
酒后驾车（DUI）会增加发生机动车碰撞的概率，尤其是对于保护措施较少的摩托车。本研究旨在确定摩托车手和汽车司机酒后驾车犯罪（即血液酒精浓度（BAC）达到 80mg/dL 或更高）的共同点和不同点。
利用来自中国江苏法院判决文件的资料，采用一系列逻辑回归模型对总共 10457 例摩托车酒后驾车和 8402 例汽车酒后驾车进行了比较。
结果显示，高 BAC 组（即 200mg/dL 或更高）的罪犯占酒后驾车总犯罪的 20%以上，且更有可能发生撞车事故并受到更长时间的拘留。与受酒精影响的汽车司机相比，摩托车手发生撞车事故的可能性更高，而且更有可能与单车事故有关，单车事故与受伤的几率更高有关。在判决中，摩托车手的犯罪者更有可能受到较轻的处罚。
显然需要采取干预措施，重点减少高 BAC 组的罪犯。对于受酒精影响的摩托车手，他们的撞车和受伤风险相对于 BAC 的上升幅度比汽车司机的风险更为陡峭。包括频繁发生、检测不确定性和短期刑期在内的因素可能会削弱酒后驾车刑事定罪的威慑效果。
与交通相关的判决数据支持交通安全分析。预计将采取打击摩托车违法行为（例如无证驾驶或驾驶不安全车辆）、开展教育和宣传活动等策略来预防酒后驾车。
