Many trucking company owners believe that because they're heavily regulated by the US Department of Transportation (DOT) and the Federal Motor Carrier Safety Administration (FMCSA), OSHA requirements don't apply to their operations. In reality, that assumption creates a significant compliance gap.
While DOT and FMCSA regulate drivers and vehicles on public highways, OSHA continues to enforce workplace safety requirements for trucking employers across many common operational settings. Understanding where OSHA applies and which standards are most frequently cited is essential for reducing injury risk, avoiding citations and protecting your workforce.
OSHA regulations versus DOT: Who regulates what?
The distinction between OSHA and DOT comes down to jurisdiction, not industry type.
Under Section 4(b)(1) of the Occupational Safety and Health Act, OSHA is preempted only when another federal agency actively regulates a specific working condition. DOT preemption is limited to hazards that the FMCSA explicitly regulates, primarily vehicle operation on public roadways. That regulation means:
- DOT/FMCSA governs driver qualifications, hours of service, vehicle maintenance and highway safety.
- OSHA governs employee safety in workplaces such as terminals, yards, maintenance shops, docks and warehouses, and during many off‑highway tasks.
In practice, most trucking companies are subject to both agencies at different points in their operations.
When OSHA regulations apply to trucking operations
OSHA has authority whenever trucking employees are exposed to workplace hazards not on public highways, including:
- Terminals, offices and dispatch centers
- Maintenance shops and tire rooms
- Loading docks and yards
- Warehouses and customer facilities
- Intrastate trucking operations
- Loading and unloading activities
- Forklift and material‑handling tasks
OSHA also retains authority over intrastate trucking, such as gravel haulers, concrete mixers, logging trucks and agricultural transport.
