Who can apply for a CDIP

Any driver over 18 years of age with a valid Washington driver license can apply for a commercial driver instruction permit (CDIP). You must be at least 21 years of age to operate commercial vehicles from state to state (interstate).

To get a CDIP, you must pass a knowledge test. You may apply for a CDIP at any driver licensing office that offers knowledge testing (call to find out). Bring the following with you:

  • Your current license.
  • Your Social Security number, which will be used for identification purposes. This is a mandatory requirement under federal law (49 USC 31308) and Washington state law(RCW 46.25.070).
  • The $10 application fee. You may pay with:
    • Cash
    • Check

How long a CDIP is valid

The CDIP is valid for 6 months and may be renewed only once.
