CDL Practice Test Prep 2026

Studying for your CDL permit test? CDL Practice Test Prep 2026 gives you nearly 900 exam-style practice questions for every CDL knowledge test and endorsement, with full-length practice tests you can take anywhere.

IMPORTANT: NOT AFFILIATED WITH ANY GOVERNMENT OR DMV

CDL Practice Test Prep is an independent study app. It is not affiliated with, endorsed by, or connected to any government, DMV, FMCSA, AAMVA, or any official testing body, and it is not the official CDL exam. The practice questions are study material written from the publicly available CDL manual. Requirements are set by FMCSA and your state DMV and can change, so always confirm the current rules on the official sources listed below.

PRACTICE TESTS SIZED LIKE THE CDL EXAM

Each practice test is the length of the standard CDL knowledge test: 50 questions for General Knowledge, 25 for Air Brakes, 30 for Hazmat and 20 for each of the other tests. Aim for 80% or better, the usual passing score.

New questions come first, so every test brings questions you have not seen yet until you have worked through the whole bank. Get instant answers and clear explanations, so you actually learn the rule, not just memorize it.

WHAT YOU CAN PRACTICE

General Knowledge (338 questions), the core test every CDL applicant takes.

Air Brakes (137 questions), to help remove the air brake restriction.

Combination Vehicles (108 questions), for Class A tractor-trailer drivers.

Whether you are studying for a Class A, Class B, or Class C license, or getting your commercial learner's permit (CLP), the question bank covers the knowledge topics for every endorsement.
