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.
车辆与行车安全Vehicle & road safety
把司机看到的车况与车队保存的检查、维修资料对起来。遇到故障或路检记录时，再进入相应法规来源。Compare the condition observed by the driver with the carrier's inspection and maintenance records. Use the related regulation source when reviewing a defect or inspection record.
经营注册与税费Registration & taxes
先确定公司做什么业务、车辆在哪里运营，再核对需要的联邦和州级记录。不要把一个号码或许可当成全部手续。Identify the business activity and where vehicles operate, then check the relevant federal and state records. One number or permit does not represent every filing.
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.
排放与检测Emissions & testing
先确认具体车辆和使用场景，再进入检测、车队或怠速规则的官方入口。不同项目的登记和记录不能互相替代。Identify the specific vehicle and use before opening the official source for testing, fleet, or idling rules. Registration and records for one program do not replace another.
