CDL Workbook is a free study aid for the learner's permit knowledge test: road-sign identification questions and plain-language pages on general driving rules, with a link to your state's official handbook. It is not affiliated with any licensing agency.
Skim the road signs catalog and the 12 traffic-law topics every exam covers. Plain explanations, no jargon.
Each state page points you to that state's official handbook and licensing agency.
Every question shows the correct answer with an explanation, so you learn the rule rather than memorizing the test.
Bring valid ID, proof of residency, and your study confidence. We'll cover the rest.
Every regulatory, warning, guide, and construction sign you may see on the test.

Twelve topic guides cover almost every question you'll see on a US permit exam.
Who goes first when two or more vehicles arrive at the same place.
Posted limits set the maximum, but conditions set the safe speed.
Safe lane changes are deliberate, signaled, and well-spaced.
Position, signal, and yield in that order.
Where you can stop matters as much as how you park.
Alcohol, drugs, and even some medications can disqualify you from driving.
Restraints reduce fatal injuries by about half.
Stop, slow, and stay out of the way.
Anything that takes your eyes, hands, or mind off the road is a distraction.
Bicyclists, motorcyclists, pedestrians, and trucks all need extra space.
Reduce speed, increase following distance, and use lights wisely.
Most states use a graduated driver licensing (GDL) system.
Most permit-test sites pile on pop-ups, lock the good questions behind paywalls, or quiz you on rules from the wrong state. CDL Workbook is built around one idea:
Every page is plain, fast-loading HTML — no app to install and nothing to wait for.
