Commercial Truck Driving
Rights and federal rules for commercial drivers — hours of service, inspections, CDL.
Commercial drivers live under a federal rulebook written by the Federal Motor Carrier Safety Administration (FMCSA). Hours-of-service limits cap how long you can drive and require rest, tracked by an electronic logging device (ELD). CDL holders are subject to drug and alcohol testing through the federal Clearinghouse, and roadside inspections follow a standardized national format.
You also have protections, not just obligations. The coercion rule makes it illegal for a carrier, shipper, or broker to pressure you into violating safety rules — for example, to drive past your hours or haul an unsafe load. The articles below cover hours of service, roadside inspections, drug and alcohol testing, the coercion rule, and your rights at weigh stations.
Your Questions, Answered
- Truck Driver Drug & Alcohol Testing: What Are the Rules? As a CDL driver you are subject to DOT drug and alcohol testing — pre-employment, random, post-accident, and on reasonable suspicion. A refusal is treated as a positive test, and any violation puts you in 'prohibited' status in the FMCSA Clearinghouse until you complete the return-to-duty process.
- DOT Roadside Inspection: What Are My Rights as a Driver? You must show your CDL, medical certificate, and record of duty status (your ELD logs), and let the officer inspect the vehicle. But officers must treat you professionally, the inspection is limited to safety compliance, and you can challenge a violation you believe is wrong through FMCSA's DataQs system.
- Can I Be Forced to Drive Over My Hours or With Unsafe Equipment? No. Federal law makes it illegal for a carrier, shipper, broker, or receiver to coerce you into breaking a safety rule — like driving past your hours-of-service limit or with an out-of-service defect. You can refuse, and you can file a coercion complaint within 90 days.
- What Are the Hours-of-Service Limits for Truck Drivers? For most property-carrying drivers: up to 11 hours of driving after 10 hours off, all within a 14-hour window, a 30-minute break after 8 hours of driving, and a 60/70-hour weekly cap.
- Do I Have to Stop at Weigh Stations — and Can They Search My Truck? If a weigh station is open and your vehicle meets the state's weight threshold, you must stop — that is an administrative safety check, not a criminal search. But to search the cab itself for evidence, officers still need your consent, probable cause, or a warrant, and you can decline consent.
