How to Transfer Your Truck Driver License to Idaho (2026)

The 30-Day Clock: Idaho CDL Transfer Basics

If you hold a valid Commercial Driver's License (CDL) from another state and are moving your primary residence to Idaho, federal commercial motor vehicle regulations require you to transfer your CDL within 30 days of establishing residency. In Idaho, residency is established when you take an in-state job, register to vote, purchase a home, sign a long-term residential lease, or live in the state for 90 continuous days.

The official state agency overseeing commercial driver licensing is the Idaho Transportation Department (ITD) Division of Motor Vehicles (DMV). Unlike states that operate standalone state-run DMV facilities, Idaho handles driver licensing through county sheriff offices across the state's 44 counties. You will complete your CDL transfer by visiting the driver licensing department within a county sheriff facility in your new home county.

If your out-of-state CDL is active or has been expired for less than one year, Idaho waives the skills test (road test) and pre-trip vehicle inspection for Class A, Class B, and Class C commercial licenses. You must surrender your physical out-of-state driver's license card when you complete the transfer. You cannot legally hold a commercial driver's license from more than one state at the same time.

Required Documents and Idaho DMV Paperwork

To avoid multiple trips to the county sheriff office, gather your original documents before you go. ITD staff will not accept photocopies or digital photos on your phone.

You must present the following documents at the counter:

• Current Out-of-State CDL: Your physical card must be valid or expired less than one year. If your card was lost or stolen, you must provide a certified driving record or clearance letter from your previous issuing state showing your commercial license status.
• Proof of Identity and US Citizenship or Lawful Presence: An unexpired US Passport, certified US Birth Certificate, or Consular Report of Birth Abroad.
• Proof of Social Security Number: An official Social Security card, W-2 form, 1099 form, or pay stub showing your full nine-digit Social Security Number.
• Two Proofs of Idaho Residency: Acceptable items include an Idaho utility bill, residential lease agreement, mortgage statement, homeowner insurance policy, or pay stub displaying your physical Idaho residential address. Post office boxes are not accepted as proof of physical address.
• DOT Medical Examiner's Certificate: Your current, unexpired Medical Examiner's Certificate (Form MCSA-5876) issued by a certified medical examiner listed on the National Registry.
• Medical Self-Certification Form: You must submit an ITD Medical Self-Certification form declaring your operating category. Most interstate over-the-road drivers fall under Non-Excepted Interstate (Category 1).

Endorsements, HazMat, and Written Testing

When transferring an active out-of-state CDL to Idaho, your basic Class A, B, or C driving privileges transfer without written knowledge exams. Endorsements follow specific rules:

• Tank Vehicle (N) and Doubles/Triples (T) Endorsements: These standard endorsements generally transfer directly from your active out-of-state license without requiring new written knowledge exams.
• Passenger (P) and School Bus (S) Endorsements: Existing valid passenger and school bus endorsements usually transfer directly. If you choose to add them during your transfer, you must pass the written knowledge test and the appropriate passenger or school bus skills test.
• Hazardous Materials (H or X) Endorsements: HazMat endorsements do not automatically transfer across state lines. Federal law requires you to take and pass the Idaho Hazardous Materials written knowledge test at the county license office. You must also complete a Transportation Security Administration (TSA) background check and fingerprinting process, or verify that your current TSA threat assessment is eligible for state transfer.

If your out-of-state CDL has been expired for longer than one year, ITD requires you to retake all commercial written knowledge tests and complete a full skills test, including the pre-trip inspection, basic vehicle control test, and road drive.

Fees, Locations, and Processing Timeline

Commercial licensing fees in Idaho vary depending on the license class and validity period. Because county administrative surcharges and state fee schedules update periodically, confirm exact current costs on the official Idaho Transportation Department DMV website before heading in.

Expect the following typical fee ranges when transferring your CDL:

• Four-Year Class A, B, or C CDL Fee: Typically ranges between $40.00 and $60.00.
• Eight-Year CDL Fee: Idaho offers an eight-year license option for drivers aged 21 to 62. Expect fees between $75.00 and $95.00.
• Endorsement Fees: Adding or transferring commercial endorsements typically costs between $15.00 and $25.00 per endorsement.
• Written Knowledge Test Fees: Knowledge exams generally cost between $3.00 and $5.00 per attempt for each test.
• County Administrative Fee: County sheriff offices add a small administrative processing fee, usually between $3.00 and $5.00.

Once your documents and payments are processed, the county officer will issue you a temporary paper driver's license. Your physical out-of-state license will be hole-punched or retained. Your permanent plastic Idaho CDL is produced at a central facility and mailed to your physical address, typically arriving within 2 to 4 weeks. Keep your temporary paper license and punched card with you while driving.

Idaho Driving Realities and Income Tax Impact

Moving your trucking career to Idaho involves adjusting to state tax structures and operating conditions.

Idaho levies a flat 5.3% state income tax on personal earnings. Whether you work as a W-2 company driver or operate as a 1099 owner-operator, factor this flat 5.3% rate into your net income planning when comparing job offers.

Regarding relocation grants, note that Idaho has no statewide programs that pay people to move to the state. Relocation incentives or signing bonuses must come directly from your prospective employer.

On the road, operating commercial vehicles in Idaho involves state-specific operational rules:

• Ports of Entry: ITD operates fixed and roving Ports of Entry on major freight lanes, including I-90 near Huetter, I-84 near Boise and Blackfoot, and US-95 near Lewiston. All commercial vehicles over 26,000 lbs must pull into open scales.
• Winter Mountain Driving: Idaho experiences severe winter weather on mountain passes like Lookout Pass on I-90, Fourth of July Pass, and White Bird Hill on US-95. Idaho law authorizes mandatory tire chain requirements during dangerous conditions. Carrying proper chain sets is mandatory for regional and long-haul drivers.
• Heavy Haul Configurations: Idaho permits commercial combination vehicles up to 129,000 pounds on designated state routes. Operating these high-weight rigs requires specialized ITD permits and specific vehicle axle configurations.

What People Get Wrong About Moving a CDL to Idaho

Avoid these common mistakes when transferring your commercial driver license to Idaho:

• Looking for a state-run DMV building: Drivers often search for a dedicated state DMV hub. In Idaho, driver licensing is handled strictly through local county sheriff offices.
• Waiting past the 30-day window: Driving beyond 30 days after establishing residency violates state law and can create compliance issues with your carrier's insurance during inspections.
• Assuming HazMat transfers automatically: Believing your HazMat endorsement moves over without testing will leave you unprepared. You must pass the written HazMat exam at the county office.
• Forgetting medical self-certification: Submitting your physical DOT card without completing the ITD Medical Self-Certification form can result in your CDL being downgraded to a Class D driver license.
• Expecting state relocation money: Assuming Idaho pays cash incentives for out-of-state workers to move is incorrect; there are no statewide move-pay programs in Idaho.
