Introduction

Bicycling has numerous health benefits, such as improvements in cardiorespiratory fitness, and significant risk reductions for cardiovascular disease, cancer, and obesity and has benefits to the environment. However, motorists' behavior has been shown to be a significant barrier for people to bicycle. Therefore, it is important to examine licensed drivers’ knowledge of the policies that guide roadway interactions with bicycles.

Methods

A cross-sectional online survey was developed and distributed to Missouri licensed drivers. A bivariate linear regression and multivariable linear regression analysis was conducted to determine which factors predict overall driver knowledge score for bicycling laws.

Results

Demographic factors such as living in non-metropolitan areas [micropolitan, small town, and rural] (p < 0.001) as well as behavioral factors such as driving greater than 50 miles per week (p < 0.001) were associated with lower test scores. Whereas bicycling 1–10 miles per week (p < 0.05) and more than 50 miles per week (p < 0.001) (reference group: 0 miles biked per week) and Type of Cyclist Interested, but Concerned (p < 0.001), Enthused and Confident (p < 0.001), and Strong and Fearless (p < 0.001) (reference group: No Way No How) were associated with higher scores on a test of roadway bicycling policies. Questions related to lane positioning, the meaning of green paint, and bicycle-related signage were the most answered incorrectly most often.

Conclusion

Drivers who do not bike have less knowledge of bicycling laws in Missouri. Interventions to promote roadway safety for bicyclists should focus on drivers who do not bike and on education related to lane positioning, green paint use, and bicycle-related signage.

有关骑车和驾驶的误解：驾驶员对密苏里州自行车法律的理解

介绍

骑自行车具有许多健康益处，例如改善心肺功能，并显着降低心血管疾病，癌症和肥胖症的风险，并且对环境有益。但是，驾驶员的行为已被证明是人们骑自行车的重要障碍。因此，重要的是要检查有执照的驾驶员对指导道路与自行车交互作用的政策的知识。

方法

开发了横断面在线调查，并将其分发给密苏里州持照驾驶员。进行了双变量线性回归和多变量线性回归分析，以确定哪些因素预测了骑自行车法则的总体驾驶员知识得分。

结果

人口因素，例如居住在非大都市地区[小城市，小镇和农村]（p <0.001），以及行为因素，例如每周行驶50英里以上（p <0.001），都与较低的考试成绩相关。而每周骑自行车1–10英里（p <0.05）和每周骑自行车50英里以上（p <0.001）（参考组：每周骑车0英里），并且对骑单车的类型感兴趣但很关心（p <0.001）测试道路骑行政策时，高分和自信（p <0.001），强壮和无畏（p <0.001）（参考组：无路无路）与更高的分数相关。与车道定位，绿色油漆的含义以及与自行车相关的标牌有关的问题最常被错误回答。

结论

不骑自行车的驾驶员对密苏里州的自行车法律知之甚少。旨在提高骑行者道路安全性的干预措施应侧重于不骑自行车的驾驶员以及与车道定位，绿色油漆使用和自行车相关的标牌相关的教育。
