What regulations must an intrastate operation comply with?

Intrastate operations involving vehicles that meet the definition of a commercial motor vehicle found in 383.5 are automatically subject to Part 382 (alcohol and drug regulations), and Part 383 (CDL regulations). Many states pick up the majority of the FMCSRs for intrastate operations, but may make exceptions or revisions for a particular size of vehicle or type of operation. A few states’ regulations have little direct correlation to the FMCSRs. Certain intrastate operations are also subject to the insurance requirements in Part 387 (when transporting specific hazardous materials outlined in 387.9) and whatever other regulations, FMCSRs or otherwise, the state has established.
