If you are 21 years or older you may obtain a permit from your current state of residence, test on that permit in Idaho, and then return to your home state to be issued your Class A CDL. You must first check with your local DMV, to ensure that they will accept the Idaho skills test results. Some states will not accept skills test results from another state. (State of Washington will NOT accept out-of-state skills test results.)
