Iowa CDL truck driver license requirements
The short answer
As of July 2026, The Iowa Department of Transportation (Motor Vehicle Division) issues CDLs under Iowa Code ch. 321: the commercial learner's permit is $12 and the CDL costs $8 per year of validity, with a standard 8-year license term (2-year terms at age 78+). CLP applicants must be at least 18, hold a valid Iowa Class A/B/C/D license, and hold the CLP at least 14 days before the skills test. Endorsements are $5 each (tanker, doubles/triples, hazmat) or $10 (passenger, school bus), and Iowa statute directly incorporates the federal ELDT, medical-certificate, and drug-and-alcohol clearinghouse requirements.
Do you need a license to work as a CDL truck driver in Iowa?
Iowa licenses CDL truck drivers statewide, so one credential is valid across the whole state.
iowadot.gov hard-blocks automated access (Cloudflare), so all core facts were taken from the official Iowa Code 2026 PDFs on legis.iowa.gov (the Iowa Legislature's site), which are the controlling authority for fees and requirements; the iowadot.gov URL is provided only as the agency's public-facing page. Fee detail (Iowa Code 321.191): CLP $12; CDL $8 per year of validity; doubles/triples, tanker, or hazmat endorsement $5 each; passenger or school bus endorsement $10; removal of air brake/manual transmission/tractor-trailer/passenger restriction $10; CMV privilege reinstatement after disqualification $20; endorsement fees are not re-charged at renewal when no new test is required. Out-of-state transfers: new Iowa residents with a conforming CDL take only a basic Iowa rules-of-the-road knowledge test (321.188(5)).

Hours are what each class asks for on its own terms. Where a senior class shows fewer than a journeyman, the board is counting time served after the earlier license rather than from the start; the prerequisite column says which.
