Iowa commercial driver's licenses
CDL pre-trip inspection
Review section 11 in the Commercial Driver License Manual
to prepare for and successfully pass the pre-trip vehicle inspection test.
CDL Pre-Trip Inspection Memory Aid
- You must successfully demonstrate all three components of the airbrake check before you start the pre-trip vehicle inspection test – prepare for this by reviewing the information in section 11.
- If you do not pass the airbrake check and/or the pre-trip vehicle inspection test, you must make another appointment to retake the test – that could be two or three weeks out, which will delay the issuance of your commercial driver’s license.
