Prepare for the General Knowledge section of your Commercial Learnerʼs Permit (CLP) test.
In the United States, there are three main classes of Commercial Driver Licenses (CDLs). A Class A CDL allows you to operate a combination of vehicles with a gross combination weight rating (GCWR) of 26,001 pounds or more, provided the towed vehicle(s) has a gross vehicle weight rating (GVWR) of more than 10,000 pounds. This class of CDL is generally for operating semi-trucks and tractor-trailers. A Class B CDL allows you to operate a single vehicle with a GVWR of 26,001 pounds or more or a combination of vehicles where the towed vehicle has a GVWR of 10,000 pounds or less. This class of CDL is generally for large buses and straight trucks, including box trucks and most dump trucks. A Class C CDL is for other kinds of commercial vehicles that transport hazardous materials or at least 16 occupants (including the driver). This class of CDL is generally for small buses (including shuttle buses) or small trucks carrying hazardous materials.
No matter which class of CDL you plan to get, you must meet a series of requirements. Notably, you must pass an official skills test, which includes basic vehicle maneuvers, a pre-trip inspection test, and a road test. To be sure of passing this test, you must practice commercial driving under supervision until you’re proficient. And for that, you’ll need a Commercial Learner’s Permit (CLP).
To obtain a CLP, you must meet certain requirements too, including passing the official General Knowledge test on the basic theory of commercial driving. The questions on this test are based on the official Utah Commercial Driver’s License Manual (Utah CDL Handbook 2026). If you’ve found absorbing the material in this manual to be tough going, perhaps you need a little more help.
This free Utah CDL permit practice test, which you’re about to take, is based on the official CDL manual, just like the official knowledge test. It’s up to date as of May, 2026. There are 20 multiple-choice practice questions on such topics as basic maneuvers, following distance, driving emergencies, and vehicle components. If you get stuck on a question, use the available hint. If you still miss a question, read the explanation of the correct answer carefully so you won’t make that same mistake again. You can also ask our automated assistant for even more help. With us, there’s no time limit; take all the time you need to learn and master the material covered by this practice test.
Be sure to try our other CDL General Knowledge practice tests too.
What to review before the CLP knowledge test and CDL endorsement practice
Based on recent Driving-Tests.org answers for this test family.
Review axle weights, load balance, center of gravity, and how weight affects braking, steering, and rollover risk.
Review engine controls, shifting, gauges, retarders, and warning signs that need attention before or during a trip.
Review emergency stops, warning devices, brake failure, tire failure, and safe roadside procedures.
Review tie-downs, blocking, weight limits, inspection timing, and what makes cargo shift during a trip.
CLP and General Knowledge requirements before skills testing and endorsements
Start with General Knowledge for your UT CLP. Add Combination Vehicles, Air Brakes, or endorsement tests only when they match the license class and endorsements you need.
Passing the written test does not give you a CDL. After your CLP is issued, federal rules require you to hold it for at least 14 days before the CDL skills test.
Pick the right medical self-certification category early. If you drive non-excepted interstate, keep your DOT medical certification current with the state licensing agency.
ELDT may be required before Class A or B skills testing, first-time Passenger or School Bus endorsements, or the HazMat knowledge test. Your training provider submits completion through FMCSA's Training Provider Registry.
Use General Knowledge as the base, then move into the CDL tests that match your license class and endorsements.
