CDL (Commercial Driver's License)

Quick answer:

A Commercial Driver's License (CDL) is valid 5–8 years depending on state. Renewal costs $60–$150 and requires a current DOT medical certificate (up to 24 months). An expired medical card automatically downgrades your CDL to a non-commercial license under 49 CFR 391.41.
