Utah CDL practice tests

Utah is one of the few states that hands driver licensing to a named division rather than a department styled as a DMV: the Driver License Division, sitting inside the Department of Public Safety. The name is worth knowing before you go looking for a "Utah DMV" website that does not exist under that name.

What Utah requires

Every figure below names the document it came from, so you can check it rather than take our word for it.

Utah practice tests

The knowledge tests are set by federal rule, so the questions are the same wherever you sit them. What changes is the paperwork above.

Where the rules come from

Almost none of what is tested is written by Utah itself. 49 CFR Part 383 is the federal rule that sets the knowledge exam content, and it is identical in substance no matter which state administers it. Passing means 80 percent correct on each section. You can drive commercially inside Utah at 18; you need to be 21 to take a commercial load over a state line. A commercial learner permit must be held for fourteen days before the skills test can be scheduled, which is federal, not a Utah rule, so plan your knowledge exams for the start of that window rather than the end.

Picking your tests

General knowledge is required of everyone. What else you need depends on the vehicle. Air brakes have their own exam; missing it does not block your license, it adds a restriction against driving equipment fitted with them. Towing over ten thousand pounds adds the combination vehicles test. Beyond those, the endorsement list is the same one used everywhere in the country: tank vehicles, doubles and triples, passenger-carrying vehicles, school bus, and hazardous materials, each with its own separate knowledge exam.

Hazmat needs more than a passing score. It requires a Transportation Security Administration background check, handled outside the exam process and on a timeline of its own, so it pays to start that step as soon as you know you will need the endorsement.

A geography note

Utah's population sits mostly along the Wasatch Front, but a good share of the state is mountain and desert a long way from it. If you live outside that populated strip, plan around the drive to a testing site rather than assuming there is one close by — the Driver License Division does not have an office in every county. Someone testing from the Uinta Basin or the far southeast corner of the state is working with a different map to someone testing from Salt Lake County, even though the exam itself is identical.

Fees are deliberately left off this page. They are set by the state, they change, and repeating a number here that has gone out of date would cost you a wasted trip. Check directly with the Driver License Division before you go. This site's job is narrower and more durable: the questions the knowledge exam asks, and the exact source each answer is drawn from.
