法规速查Regulation Navigator
从正在处理的运输事项出发，阅读法规解读，查找原文与官方来源。Start with the trucking task at hand, read an explanation and find the regulation and official sources.
你正在办理哪件事？What are you working on?
从工作中遇到的事情开始，了解相关要求、常见误会和处理方法。Start with a work situation to understand the requirements, common mistakes and next steps.
驾照与驾驶资格Driver qualifications
从驾照、体检、司机档案和药酒测试记录开始，找到与你当前情况有关的法规入口。Start with the license, medical status, driver file, and drug and alcohol records to find the rules that fit your situation.
工时与驾驶记录Hours & logs
把驾驶、工作、休息和电子日志放在同一条时间线上核对。这里提供查找方向，不替你判断一次具体行程是否合法。Compare driving, work, rest, and electronic logs on one timeline. These paths help you research the rules without deciding whether a specific trip is compliant.
体检、视力与健康资格Medical certification and fitness
体检证书有各自的有效期，部分司机还需按更短周期复查。受伤或患病后，即使证书尚未到期，也可能需要重新体检才能继续驾驶。Check whether medical certification is valid and whether a shorter examination interval applies. An unexpired certificate does not automatically authorize driving after a disqualifying injury or illness.
司机入职与资格档案Hiring and driver qualification files
司机入职后，车队须按期调查驾驶记录和前雇主安全表现，之后还要年度复核并保存档案。各项工作应留下完成时间和证明材料，仅收取驾照还不足以安排驾驶。Hiring inquiries, annual reviews and file retention are separate tasks. Track each deadline and supporting record instead of dispatching after collecting only a license.
药物、酒精检测与 ClearinghouseDrug testing and the Clearinghouse
上岗前检测、事故后检测和 Clearinghouse 查询的适用条件各不相同。司机和承运人须分别完成所需检测与查询，一项通过，并不免除其他要求。Pre-employment testing, post-accident testing and Clearinghouse queries have different triggers. Drivers and carriers must check them separately rather than use one as a substitute for another.
短途工时例外与适用条件Short-haul exceptions and conditions
短途记录例外有运行半径、返回时间、休息和时间记录等条件。满足记录例外后，司机仍须遵守适用的驾驶时限。Check the radius, return/release time and carrier time records before using the short-haul recordkeeping exception. Short-haul does not mean unlimited driving.
ELD 修改、故障与未归属驾驶ELD edits, malfunctions and unidentified driving
更正 ELD 日志时须保留原始记录，并按实际驾驶情况确定归属。设备故障与一般数据诊断提示的处理要求不同，使用纸质日志前应弄清发生了哪种情况。Logs can be corrected without erasing the original record. Resolve actual driving attribution, then distinguish an ELD malfunction from a data diagnostic event.
