Utah CDL Practice Test

General Knowledge 50 questions, Air Brakes 25, Combination 20, Hazmat 30, and Tank, Doubles/Triples, Passenger and School Bus 20 each. Every CDL test is closed-book multiple choice and needs 80% to pass.

The Utah Commercial Driver License Handbook (2025 edition): Utah’s own introduction (requirements, medical certification, restrictions, endorsements, records and disqualifications) and the national AAMVA sections on inspection, safe driving, cargo, passengers, air brakes, combination vehicles, doubles and triples, tankers, hazardous materials and school buses.

No. All Utah CDL tests are given in English only and translation materials are not allowed. Each core test may be taken twice before a retest fee applies.

Everyone applying for Class A, B or C takes General Knowledge. Class A applicants add the Combination test. Air Brakes is for Class A or B drivers who will use air-braked vehicles; skip it, or test in a truck without air brakes, and Utah adds the L restriction. Endorsement tests are optional.

80% on each of the 8 tests, each graded on its own (General Knowledge: 40 of 50). Every test's numbers are in the table on this page. Always confirm the current tests with the Utah Department of Public Safety, Driver License Division. Why 80% in every state →

You must be at least 18, have held a driver license for one year, and have a current medical examiner’s certificate (submitted by your medical examiner before your appointment) and the self-certification form. Under 21 you can’t get the Passenger, School Bus or Hazmat endorsements.

Once you pass every written test you need, Utah issues the permit for 180 days. You surrender your regular license when you receive it, and the permit lets you drive your own car as well.

A pre-trip vehicle inspection, a basic control skills test (forward stop, straight-line backing, forward offset tracking and reverse offset backing; 8 or fewer error points) and a road test (30 or fewer error points). Complete ELDT first and bring your own registered, road-ready vehicle. Tests are given at the Driver License Division or by a third-party tester.

Yes, if you are getting a Class A or B CDL for the first time, upgrading from B to A, or adding School Bus, Passenger or Hazmat for the first time. The theory part can come first; behind-the-wheel training needs a permit. Hazmat applicants finish the theory part before the written test.

Utah Department of Public Safety, Driver License Division lists the current fees for the commercial learner permit, the CDL tests and the license on its official fee page.

Only someone who holds a CDL for the class and endorsements of the vehicle you are driving, or an examiner the Driver License Division has certified to give CDL tests. That person must sit in the seat beside you to teach you or test you.

No. Each CDL renewal needs a new application with updated information and the required certifications, so it can't be done over the internet. If you move or change your name between renewals, you have 30 days to apply for a replacement license.

Book an appointment at a Driver License Division field office, pay the fee for the change and sign a form saying you are giving up your CDL. You leave with a regular Class D license.

Only until you have lived in Utah for 30 days in a row. After that, Utah law doesn't let you drive a commercial vehicle on another state's CDL. When you transfer, you list every state that licensed you in the past 10 years.

A TSA and DOT background check every five years (or a valid TWIC card, checked at a Driver License office), the 30-question hazmat written test every five years, and the ELDT theory course before the first hazmat test. The X endorsement adds the 20-question tanker test.

Yes. The School Bus endorsement needs the passenger and school bus written tests and a skills test in a school bus, and the school bus written test is taken again at every renewal.

You may qualify for Utah’s intrastate waiver program (for pulmonary, neurologic, seizure, learning/memory, psychiatric or musculoskeletal conditions) and a K restriction that allows commercial driving within Utah only.

Pick one of four. Non-excepted interstate: a valid DOT medical card and age 21 or older. Excepted interstate: only excepted work such as government or school bus driving, also 21+. Non-excepted intrastate: Utah's intrastate waiver card. Excepted intrastate: under 21 with a valid medical card. Both intrastate choices bring the K restriction.

When you first get a CLP or CDL, upgrade or renew it, transfer a CDL from another state, and whenever your type of driving changes. Knowingly giving false information on the form is a Class B misdemeanor in Utah and can disqualify your license.

Utah law requires your CDL to be downgraded to a regular Class D license if you don't send the medical certificate or self-certification the division asks for, or if the division decides you are no longer medically qualified to drive a commercial vehicle.

Veterans honorably discharged in the past year who drove a commercial vehicle in the two years before discharge can have the skills tests waived; they still pass every written test. School Bus and Hazmat endorsements can’t be transferred under the waiver.

No. Since January 20, 2026, Utah has paused issuing non-domiciled CDLs until further notice.

The license application, the CDL-ST WVR form (your last commanding officer completes page 2), a DD214 or discharge papers showing an honorable discharge in the past year (reservists bring their last orders), and a DA348, AF2293 or similar record of your CMV training. You still pass every written test.

Yes. If you didn't drive a vehicle with air brakes or a manual transmission in the service, Utah adds an air brake or automatic transmission restriction. To remove it, pass the skills test in a representative vehicle. Waiver applicants don't need Entry-Level Driver Training.

Under the current federal rule, at least 180 days for a first violation, 2 years for a second within 10 years and 3 years for a third (longer when hauling placarded hazmat or driving a vehicle for 16 or more people). The handbook still prints the older 90-day figure.

Yes. When Utah takes administrative action against your driving privilege over a DUI arrest, the division also disqualifies your CDL: one year, or three years if you were hauling hazardous materials. A disqualification after a conviction starts seven days after you are notified.

Yes. A guilty or no contest plea held in abeyance for a disqualifying offense brings the same CDL disqualification as a conviction, even if the charge is later reduced or dismissed. The plea stays on your driving record for 10 years, even after an expungement.

Sometimes. After at least 10 years, a driver who has finished an approved rehabilitation program and meets the division's standards may apply for reinstatement. It's never possible after a drug-trafficking or human-trafficking felony, and another disqualifying offense after reinstatement makes the ban permanent.

Yes. The division may suspend or disqualify a CDL right away, without a hearing or a conviction, if it was issued by error or fraud, the application had false or missing information, the driver cheated on a CDL test, no longer meets the fitness standards or is an imminent hazard.
