Unique State Trucking Regulations in the U.S.

Weight and Size Restrictions

States may set stricter limits on truck weight, height, or length than federal minimums.
Example: Certain states restrict oversized loads on specific highways or require special permits.

Speed Limits

Truck speed limits often differ from those for passenger vehicles.
Example: California enforces a 55 mph speed limit for most trucks, lower than for cars.
Violations may serve as evidence of negligence in accidents.

Environmental Regulations

Some states impose strict emissions and idling limits.
Example: California’s CARB regulations mandate cleaner engines and limit idling time for trucks.
Non-compliance can expose trucking companies to liability if linked to mechanical failure or unsafe operation.

Insurance Requirements

States may require higher minimum liability coverage than federal law.
Example: Some states mandate extra coverage for hazardous materials or intrastate carriers.

Licensing and Training Standards

States may impose additional training, testing, or endorsements for commercial drivers beyond federal CDL requirements.
Example: Hazardous material transport endorsements often have state-specific procedures.

Intrastate Hours of Service Rules

Some states adopt their own Hours of Service (HOS) rules for trucks operating only within state borders.
These may differ from FMCSA standards, affecting fatigue-related accident claims.

Impact on Truck Accident Cases

Plaintiffs can use violations of state-specific regulations to strengthen negligence claims.
Defense attorneys may argue compliance with federal law if state rules are less clear.
Courts consider both federal preemption and state-level enforcement when evaluating liability.

Summary: Unique state trucking regulations—covering speed, weight, emissions, insurance, and licensing—play a crucial role in accident litigation. Violations of these rules can establish liability and significantly influence the outcome of truck accident cases.
