Getting a commercial driver’s license (CDL) requires knowledge-based tests and a three-part skills test. In Iowa, these tests are offered at DOT driver’s license service centers, select county treasurer locations, or third-party testers. See all current CDL testing locations.
Third-party testers are companies or agencies that are authorized and trained by the Iowa DOT to administer CDL knowledge and skills tests. The tests given by third parties are identical to tests given by the DOT and county treasurers, however, there may be fees and/or class enrollment requirements associated with third-party testers. The standards governing third-party CDL testing can be found in the Code of Federal Regulations and the Iowa administrative rule 761—607.30(321).
