Real or simulated cycling tests under the influence of alcohol might be biased by laboratory settings. Accident analyses consider incidents with injuries only. Herein, criminal offenses consisting of drunk cycling are evaluated in detail to fill this gap.
All police-recorded cases of cycling under the influence of alcohol that took place in Düsseldorf, Germany, from 2009 to 2018 were identified. A total of 388 respective prosecutor's files were available for analyses.
Mean blood alcohol concentrations were approximately 2 g/kg in both men and women. Men were overrepresented (6:1). Almost 60% of the cases were recorded between Friday and Sunday (the "weekend"). The average blood alcohol concentration (BAC) at night (01:00-05:59) was 0.39 g/kg lower than that during the day (06:00-17:59). Drinking after cycling allegations appear almost irrelevant among (German) cyclists. On average, the legal outcomes show 33 daily rates (median: 30). Additionally, the presented data raise doubts about whether the utilized medical tests or the ways in which they are carried out reliably discriminate between different grades of intoxication. Negative tests did not exclude high BACs, nor did positive tests correlate well with BACs.
DISCUSSION/CONCLUSION: In practice, CUI is seen with BACs above 1.60 g/kg in most cases. BACs below 1.60 g/kg either seem to be a minor problem or they have been incompletely addressed thus far. In summary, to be prosecuted, drunk cyclists have to ride their bikes in either a highly insecure or rude manner or they must cause an accident.
在酒精影响下进行的真实或模拟骑行测试可能会受到实验室环境的影响。事故分析仅考虑有受伤的事件。在此，详细评估了由醉酒骑行构成的犯罪行为，以填补这一空白。
确定了 2009 年至 2018 年期间在德国杜塞尔多夫发生的所有有记录在案的醉酒骑行案例。共有 388 份相应的检察官档案可供分析。
男性和女性的平均血液酒精浓度约为 2g/kg。男性的比例过高（6:1）。近 60%的案例发生在周五至周日（“周末”）。夜间（01:00-05:59）的平均血液酒精浓度（BAC）比白天（06:00-17:59）低 0.39g/kg。在（德国）骑自行车的人中，酒后骑车的指控似乎几乎无关紧要。平均而言，法律结果显示 33 天的罚款（中位数：30）。此外，所提供的数据让人对所使用的医学测试或其执行方式是否能可靠地区分不同程度的醉酒产生了怀疑。阴性测试并不能排除高 BAC，阳性测试也与 BAC 相关性不佳。
讨论/结论：在实践中，大多数情况下，CUI 被认为是在 BAC 超过 1.60g/kg 的情况下发生的。BAC 低于 1.60g/kg 要么似乎是一个小问题，要么迄今为止尚未得到充分解决。总之，醉酒骑车者要么以非常不安全或粗鲁的方式骑车，要么造成事故，才会被起诉。
