How do I prepare for the Utah CDL knowledge test?
If you are preparing for your first permit, start with general knowledge and the official Utah instructions below. If your vehicle needs air brakes or combination vehicles, add those federal study sets; for hazardous materials, use the separate hazmat set. Compare the state’s published test rules with its current manual before you test. These practice sets teach federal topics and do not copy the state exam.
This page is study material. It is not the Utah state exam, and it does not copy state test questions. Check the official Utah pages below before you test.
| Your situation | Start with… |
|---|---|
| A quick first try | Take a 10-question warm-up |
| Ready for a longer attempt | Take the 50-question general knowledge exam |
| Need state rules or documents | Check the Utah application steps |
Utah official CDL manual (PDF) — link checked . Study its rules alongside our federal-standard bank. Our 50-question exam length is a study setting; use the official counts below for Utah.
Utah DLD’s written-test page prints the general knowledge, combination and air-brake test counts and an 80 percent passing score. Its CDL information page prints the endorsement counts. Both were checked November 12, 2026. These figures describe Utah’s tests; our federal study sets do not copy Utah exam questions.

DLD’s written-test page lists a $52 license application fee including the core tests. Each test allows two attempts before a further $26 test fee. Endorsement written tests cost $9 for two attempts, with another two attempts costing $9; these are not a combined application total. Official source — checked .
DLD describes the written tests as closed book and multiple choice. All CDL tests are in English, and translation materials are prohibited. The written-test page says the permit is issued for 180 days after the required knowledge tests are passed. Official source — checked .
The school bus endorsement is added to the passenger endorsement and requires both the passenger and school bus written tests plus a school bus driving skills test. DLD requires applicable entry-level driver training before first-time passenger or school bus skills testing and before a first hazmat knowledge test. Official source — checked .
For unknown figures, check with the Utah licensing agency. A blank count is not an estimate.
Federal study sets, not the Utah exam
Use general knowledge, air brakes, combination vehicles, and hazmat to study the federal topics. Finishing one of those sets does not mean you passed the Utah test.
