How to Get a CDL Permit in Idaho
Idaho's CDL process splits into four separate fees: $40 to apply, $3 per written test, $29 for the CLP, and $70 for the skills test.
Line up your license and medical certificate first
You need a valid regular Idaho driver's license before applying, and must be at least 18 to drive commercially within Idaho, or 21 to cross state lines or transport hazardous materials, under federal rules that apply nationwide.
Complete a medical examination confirming you meet federal physical standards to operate a commercial vehicle.
Pay the application fee and pass the knowledge test
Pay the $40 application fee, then pay $3 per written test to pass the General Knowledge test — 50 questions, 80% required — plus combination-vehicle and air-brake tests if applicable to your training vehicle.
Pay the $29 CLP fee to receive your commercial learner's permit; it's valid for a full year.
Wait out the 14-day holding period
Idaho requires holding the CLP for at least 14 days before the skills test can be scheduled, per federal rule, so build that gap into your timeline from the start.
Use the wait productively: most CDL training programs schedule behind-the-wheel practice during this window.
The skills test and beyond
Pay the $70 fee and pass your skills test for the CDL class you applied for.
Receive your Class A, B, or C commercial driver's license, with any endorsements reflecting the additional tests you passed.
