Utah CDL Test Questions 2026: Counts, Passing Score and Retakes
Utah CDL knowledge tests in 2026: 50 General Knowledge questions, 25 Air Brakes, 20 Combination Vehicles, 80% passing, English-only testing, and retake fees.
Utah publishes unusually specific information about its core CDL written tests. The exams are closed-book, multiple choice, administered in English only, and require 80% to pass. The $52 CDL written-test fee includes the three core test types and gives you up to two attempts per test before an additional written-test fee is required.
General Knowledge: 50 questions
All Class A, B, and C CDL applicants take General Knowledge. Utah says the test covers general trucking knowledge, safe driving, transporting cargo, and vehicle inspection. Passing it is the foundation for the commercial learner permit.
Air Brakes: 25 questions
The Air Brakes test is needed if you plan to drive a commercial vehicle equipped with air brakes. If you do not complete the appropriate written test and skills test in air-brake equipment, the license can carry an air-brake restriction.
Combination Vehicles: 20 questions
Class A applicants take the Combination Vehicles test. It focuses on tractor-trailer and other combination-specific topics such as coupling, inspection, air systems, off-tracking, and combination-vehicle handling.
Passing score and language
Utah requires 80% on CDL written tests. All CDL tests are in English and translation materials are prohibited. Do not confuse this with Utah's regular driver-license test, which has broader language options.
Retake rules and cost
Each core written test can be taken up to two times under the $52 CDL written-test transaction. After that, Utah lists a $26 retake CDL written-test fee. Endorsement tests cost $9 and include two attempts, with another $9 for additional attempts.
What to study
Use the current Utah Commercial Driver License Handbook. Utah DLD says all CDL written questions are based on that handbook. Practice tests should be used to check comprehension after studying the manual, not as a substitute for reading the sections required for your class and endorsements.
