Free CDL Video Lessons: Every Topic on the General Knowledge Test

If you’re studying for your CDL knowledge test, watching someone walk through a topic out loud often clicks faster than reading a manual page. Exam Practice Hub now has a full set of free CDL video lessons covering every major topic on the general knowledge test, each paired with practice questions you can use right after watching.

What’s Covered

The video library is built around the actual topics tested on the CDL general knowledge exam, not a generic trucking overview. Ten core lessons plus five rapid-fire drill videos:

• CDL Classes & Endorsements — Class A, B, C, and what each endorsement (H, N, P, S, T) actually authorizes you to drive
• Pre-Trip Inspection — the sequence examiners expect, and why it’s tested on both the written and skills exam
• Air Brakes — the pressure numbers (100-125 psi normal, 60 psi warning, 20-45 psi spring brake activation) that show up constantly on the test
• Combination Vehicles & Coupling — off-tracking, splash and spray, and how to do a proper tug test
• Backing & Docking — the GOAL method (Get Out And Look) and why most backing accidents are preventable
• Cargo Securement — weight distribution and tie-down requirements
• Hours of Service — the 11-hour driving limit, 14-hour window, 30-minute break rule, and the 60/70-hour weekly limit
• Vehicle Inspection & Defect Reporting — DVIRs and what to do when you find a problem mid-trip
• Speed & Space Management — why commercial vehicles need more following distance than cars
• Extreme Conditions & Skid Control — downgrades, jackknifing, and how to recover from a skid

Each lesson runs about 2 minutes: a short explanation of the concept, then an exam-style question with the answer explained. The five drill videos skip the teaching and go straight to rapid-fire practice — 10 fresh questions each, back to back, for once you’ve already learned the material and just want reps.

Why Video Helps for the CDL Test

The CDL knowledge test uses very specific phrasing pulled from the Federal Motor Carrier Safety Regulations and your state’s CDL manual. A lot of test-takers know the concept but get tripped up by exactly how a question is worded. Hearing the same numbers and definitions explained out loud, in the same phrasing the test uses, helps that terminology actually stick — especially for pressure ranges and Hours of Service limits, which are two of the most commonly missed topic areas.

How to Use the Videos

Watch each lesson once, then immediately try the built-in question before moving to the next topic — don’t binge all ten in a row without testing yourself in between. Once you’ve been through all ten lessons, run through the five drill videos to check what actually stuck. If a topic still feels shaky, go back and rewatch just that lesson rather than restarting the whole set.

The videos are built into the CDL Practice Tests course alongside the full question bank, so you can move between watching a lesson and drilling more questions on the same topic without leaving the course. If you want a no-signup preview first, the free CDL flashcards and free CDL quiz are a good place to start.

Frequently Asked Questions

Are the CDL videos free?

The lesson videos are part of the CDL Practice Tests course. A free preview quiz and flashcard set are also available with no signup required.

Do the videos cover air brakes and Hours of Service in detail?

Yes — both are dedicated lessons, since they’re two of the most number-heavy, frequently-missed topics on the CDL general knowledge test.

Is this content specific to New York?

The CDL knowledge test is based on federal FMCSA regulations, so the core content applies nationally. Always confirm any state-specific requirements against your own state’s CDL manual before test day.
