Utah Class B CDL Practice Questions

This Utah Class B CDL practice set contains 100 original English-language questions tied to the current saved question bank. It covers general commercial-driving knowledge, air brakes, hazardous materials, tank vehicles, passenger vehicles, and school buses. The four-choice format and 100-question count are features of this practice resource, not a claim about the exact format or size of Utah’s official examinations. Utah DLD bases commercial knowledge tests on the official CDL handbook, administers CDL tests in English, and uses separate tests depending on the CDL class, vehicle equipment, and endorsements needed. Use missed questions to identify handbook sections to review, then confirm your own document, medical, ELDT, permit, endorsement, and skills-test requirements with Utah DLD before scheduling.

LICENSING GUIDE

What to know before you test

Use this overview together with the latest official guidance linked below.

Know what Utah Class B covers

Utah identifies Class B as a single vehicle, or certain combined vehicles, with a gross vehicle weight rating of 26,001 pounds or more when the towed unit does not exceed 10,000 pounds. Drivers ages 18 through 20 may qualify for intrastate-only commercial operation, while interstate operation is generally limited to drivers age 21 or older. This mixed practice bank therefore emphasizes general commercial-driving knowledge and air-brake topics while treating passenger, school-bus, tank, and hazardous-material subjects as conditional specialty material. Those topics become relevant only when the actual vehicle, cargo, or passenger operation requires the related endorsement or restriction rules.

Follow the Utah CLP and testing sequence

Utah DLD says an original CDL applicant must be at least 18 years old and have held a Class D license for one year. Applicants take the required written knowledge tests and, after passing, receive a commercial learner permit. Before the Class B driving skills test, a first-time applicant should have held the CLP for at least 14 days and completed applicable Entry-Level Driver Training through a registered provider. The skills-testing stage evaluates vehicle inspection, basic vehicle control, and on-road driving. Utah allows the skills test through the Driver License Division or an approved third-party tester, but the applicant must still meet the licensing and documentation requirements before issuance.

Prepare documents, medical status, and written tests

For an original Utah CDL, DLD instructs applicants to gather proof of identity, Social Security number, Utah address, a current driver license, and medical information. The Medical Examiner's Certificate is generally submitted electronically by the medical examiner, and commercial drivers also self-certify the type of interstate or intrastate operation they expect to perform. Utah CDL written knowledge tests are closed-book, multiple-choice, English-only exams based on the CDL handbook and require 80 percent to pass. Because required tests vary with class, vehicle equipment, and endorsements, applicants should use the DLD class and endorsement guidance instead of treating every module in this mixed practice bank as mandatory.

Use the mixed bank as targeted review

Start with vehicle inspection, general operating rules, cargo handling, speed and following distance, hazard awareness, and safe decision-making because those concepts apply broadly to Class B operation. Then review air-brake questions when the vehicle uses air brakes. Passenger and school-bus questions are most relevant when the intended Class B vehicle carries passengers and the corresponding endorsements are required; tank and hazardous-material questions are likewise conditional on vehicle configuration and cargo. After each missed item, read the cited handbook section and identify the rule behind the answer instead of memorizing the option letter. The saved questions remain draft educational content pending independent review and are not official Utah examination questions.

REQUIREMENTS OVERVIEW

Utah CDL Class B requirements

Requirements depend on the applicant and can change. Verify each item with the cited agency.

age

Applicants seeking an original Utah Class B commercial learner permit or CDL.

Utah DLD requires a CDL applicant to be at least 18 years old and to have held a Class D driver license for one year. Drivers ages 18 through 20 are limited to intrastate commercial operation; interstate commercial operation generally requires age 21.

documents

Applicants preparing for a Utah original Class B CDL appointment.

Utah DLD lists proof of identity, Social Security number, Utah address, a current driver license, and medical/self-certification information among the items needed for the original commercial licensing process.

tests

Utah Class B applicants taking required CDL knowledge and skills tests.

Utah CDL knowledge tests are closed-book, multiple-choice, English-only tests based on the CDL handbook. Required tests depend on CDL class, vehicle equipment, and endorsements, and the Class B skills process includes vehicle inspection, basic control, and road testing.

passing

Applicants taking Utah CDL written knowledge tests and the required Class B skills tests.

Utah DLD states that commercial written knowledge tests require 80 percent to pass. Applicants must also successfully complete the applicable skills-test components before CDL issuance when a skills test is required.

applicability

First-time Class B applicants and drivers seeking passenger, school-bus, or hazardous-material endorsements.

Federal Entry-Level Driver Training generally applies to first-time Class B applicants before the CDL skills test and to first-time P, S, or H endorsement applicants before the applicable skills or knowledge test. Class B authority does not by itself grant every specialty endorsement represented in this mixed practice bank.
