Getting Your CDL in Iowa
How to book the skills test
Iowa CDL tests are given at Iowa DOT driver's license service centers, at select county treasurer offices, and by Iowa DOT-authorized third-party testers (companies and schools that give the identical test, often with class enrollment or their own fee). Request a skills-test appointment at a DOT or county treasurer location online once you have held the CLP for 14 days and completed ELDT. You must provide a registered vehicle in good working order that matches the class you are applying for; a pre-trip inspection memory aid is allowed during the test.
Wait times and timing tips
Iowa DOT warns that if you fail the air-brake check or pre-trip inspection you must book a new appointment, and that retest slot "could be two or three weeks out," so treat the first attempt seriously. Third-party testers are usually the fastest route if the nearest state slot is weeks away.
