Intrastate
Commercial vehicle operations that begin and end within a single state's borders without crossing into other states.
Intrastate CDL drivers may be subject to state-specific standards rather than all federal FMCSA rules. Some states have different age minimums, medical standards, or exemptions for intrastate-only operations.
Which federal rules apply to intrastate CDL drivers
Intrastate CDL drivers are not subject to all FMCSA regulations. Many federal rules (Parts 391, 382, and 395) are written specifically for interstate operations. States may have their own parallel rules for intrastate operations, but the specific requirements vary. Some states adopt the federal regulations by reference; others have partial or modified standards. Carriers operating solely within a single state should verify with that state's transportation agency which regulations apply to their specific operation.
Intrastate CDL age and medical exemptions
Federal CDL rules set a minimum age of 21 for interstate CMV operation. States can issue CDLs to drivers as young as 18 for intrastate-only operations. Similarly, states may have their own medical standards for intrastate CDL holders that differ from the DOT physical requirements. Drivers qualifying under a state intrastate medical or age exemption who later move to interstate operations must meet all federal standards — including age 21 and full DOT medical certification — before crossing state lines.

When this definition matters
This term usually matters when a driver, owner-operator, or small carrier is deciding whether a federal rule applies, preparing a compliance file, or checking a state CDL step. Use this definition as a starting point, then confirm the controlling requirement in the official source listed below before making a licensing, hiring, dispatch, or recordkeeping decision.
The related terms above are included because they often appear in the same compliance workflow. Reviewing them together can prevent common mix-ups, such as treating a state licensing step as a federal carrier obligation or confusing a driver record with a separate employer record.
