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.
路检、停车警示与事故记录Roadside inspections, warnings and crash records
路检或事故发生后，应先保障现场安全，再按要求交接报告、处理缺陷并办理申报。检查报告、停驶命令和事故申报各有后续义务与期限。Inspection reports, out-of-service orders and accident reports are different matters. Secure the scene first, then handle handoff, repairs and deadlines separately.
加州 CA 号码与 MCP 许可California CA numbers and MCP permits
MCP 是加州承运经营许可，与车牌、联邦登记号码各有用途。业务属于适用范围时，承运人须持有效许可，并维持保险、按期续期。An MCP is California’s carrier operating permit; registration plates or a federal number cannot replace it. Determine applicability, then check permit, insurance and renewal status.
跨州车牌、IRP 与行驶记录IRP registration and distance records
IRP 里程申报须有每辆车的实际行程作为依据，包括空驶、州内路段和调车。一次从加州送货到邻州的运输，司机要记录去程和返程，办公室据此汇总里程。IRP distance reporting must trace back to each vehicle’s actual trips, including empty, intrastate and repositioning movements. A California-to-neighboring-state trip illustrates what the driver keeps and how the office summarizes it.
IFTA、燃油许可与税务记录IFTA, fuel permits and tax records
燃油的购买地点，以及车辆在哪些州使用燃油，都须有记录。即使一个季度没有跨州行驶，已有 IFTA 账户的车队也应查看本期申报要求。Where fuel is purchased and where the vehicle uses it are separate records to preserve. A quarter without interstate trips illustrates why an existing IFTA account still needs filing and record checks.
加州怠速与驾驶室供电California idling and cab power
加州重型柴油车停车供电时，主发动机怠速与其他供电设备适用的要求有所不同。以司机停车等待为例，五分钟的一般限制还须结合设备条件和具体例外理解。When parking a heavy diesel truck in California, distinguish the propulsion engine from other power equipment before checking restrictions. A waiting-at-a-stop example shows why “five minutes” is not the whole rule or a substitute for its conditions.
冷机 TRU 环保要求Transport refrigeration unit emissions requirements
冷藏运输中的柴油冷机有独立环保要求，牵引车的检测结果不能说明冷机是否合规。临时换挂冷藏拖车时，应向设备提供方索取机组资料，并查阅 CARB 项目信息。Refrigerated transport requires checks beyond the tractor: the diesel refrigeration unit has its own emissions program. A last-minute trailer swap illustrates which official program records to check before accepting the equipment.
TWIC 与港区人员准入TWIC and secure-area access
TWIC 是人员安全准入凭证，港口对车辆、承运人和具体任务还另有要求。首次进港提箱前，司机需要确认办证情况、卡片有效性及码头的现场安排。TWIC is a personnel-security credential, not a substitute for port requirements on vehicles, carriers or the job itself. A first container pickup illustrates enrollment, card validity and facility-access checks.
危险品运输基础与接单判断Hazmat basics and shipment checks
承接危险品运输，需要具备相应人员训练、运输文件、贴牌和应急资料。货物上有 UN 编号或客户提供了 SDS，只说明其中部分信息，仍须检查完整的运输要求。Before accepting hazardous material, check training, shipping papers, placards and emergency information. A UN number or an SDS alone does not establish transport compliance.
