Getting your Commercial Learner’s Permit (CLP) is the first step to becoming a truck driver. But before you can hit the road, you’ll need to pass the CDL permit test.

Here’s what to expect—and how to ace it.

WHAT’S ON THE CDL PERMIT TEST?

The written knowledge test includes multiple-choice questions pulled directly from your state’s CDL manual. The test is usually divided into several sections:

🧠 General Knowledge

Covers driving laws, road safety, and vehicle operation basics.

🔧 Air Brakes

If you plan to drive a vehicle with air brakes, you must pass this section.

🔗 Combination Vehicles

Required for Class A applicants—covers tractor-trailer safety and controls.

Other sections (like Hazmat, Passenger, or Tanker) may appear if you’re applying for endorsements.
