CDL Permit Practice Test
119 Questions
Pass all three DMV knowledge tests for your Commercial Learner's Permit on the first try — General Knowledge, Air Brakes, and Combination Vehicles. $15 on its own, or bundled with CDL A & CDL B ELDT for $45.
Getting your Commercial Learner's Permit means passing three separate knowledge tests at the DMV — General Knowledge, Air Brakes, and Combination Vehicles. All three are usually taken the same day, and you need at least 80% on each to pass.
This practice test gives you 119 DMV-style questions covering every topic across all three exams, with an explanation after every answer. Questions shuffle on each attempt, retakes are unlimited, and it works on any device.
The Three CDL Permit Tests
| Knowledge test | Real test | To pass | Practice questions here |
|---|---|---|---|
| General Knowledge | 50 questions | 40 correct — 80% | 50 |
| Air Brakes | 25 questions | 20 correct — 80% | 35 |
| Combination Vehicles | 20 questions | 16 correct — 80% | 34 |
Class A applicants take all three. Class B applicants take General Knowledge and Air Brakes only — the Combination section is included here for when you upgrade. Question counts follow the federal model; confirm with your state licensing agency.
The CDL A & CDL B Complete Bundle includes CDL A Theory ELDT + CDL B Theory ELDT + this practice test — everything from first enrollment to permit in hand. Saves $10 versus buying all three separately.
- CDL A Theory ELDT — FMCSA-registered, auto-submitted to TPR ($20 value)
- CDL B Theory ELDT — FMCSA-registered, auto-submitted to TPR ($20 value)
- CDL Permit Practice Test — 119 questions, all 3 test sections ($15 value)
- Unlimited attempts on any device
What's Inside — 119 Practice Questions
Vehicle inspection, cargo securement, safe driving, hazard recognition, skid recovery, alcohol rules, hours of service, and the following-distance and stopping-distance numbers people miss.
Brake components, governor cut-in and cut-out, the low-air warning at 60 psi, inspection procedure, ABS, brake fade, spring brakes, tank drains and brake lag. This is the section people fail most.
Fifth wheel coupling and the pull test, glad hands, air lines, rearward amplification, jackknife recovery, off-tracking, converter dollies, and doubles and triples procedures.
Right or wrong, you find out why immediately. Wrong answers are built from the mistakes drivers actually make, so a miss teaches you something instead of just costing a point.
Randomised on every attempt so you can't memorise the order — exactly like the real DMV test. Practise until you're scoring 90% or better consistently before test day.
Works on phone, tablet or computer. No download, no app store. Bookmark it and study on a break, during a commute, or anywhere with a connection.
Where This Fits in the CDL Process
Planning to Add Endorsements?
Your permit gets you the license class. Endorsements are separate — each has its own knowledge test, and some require their own ELDT for first-time applicants.
