A Commercial Learner's Permit works like the learner's permit you had before your first car license. You earn it by passing the General Knowledge test, then you practice on public roads with a licensed CDL holder sitting beside you. You must hold the permit at least 14 days before you can take the skills test, and new Class A and Class B applicants also complete entry-level driver training first. Endorsements on a permit are limited, so the permit is for learning, not for working.
Why this matters
The CLP is the only legal way to practice driving a commercial vehicle before you have a CDL, and the state will not schedule your skills test until you have passed the General Knowledge test and held the permit for at least 14 days.
The college version
In normal terms
- Pass the General Knowledge test and any tests your vehicle needs, then the state issues the CLP.
- Hold the permit at least 14 days before you can take the skills test.
- Every time you drive, a driver with a valid CDL for that vehicle must be in the passenger seat.
- Finish entry-level driver training from a registered provider before the skills test if you are going for Class A or B.
Concepts in this outline
- Commercial Learner's Permit (CLP) — The temporary permit that lets you practice driving a commercial vehicle on public roads with a licensed CDL holder in the seat beside you.
- Must pass General Knowledge test first — The General Knowledge exam is the gate to the permit; you cannot receive a CLP until you have passed it.
- Hold 14+ days — You must keep the permit at least 14 days before taking the skills test, giving you a minimum window for supervised practice.

Explain it like I’m 10
Nobody learns to ride a bike from a book. At some point you get on, and someone runs beside you. The Commercial Learner's Permit, or CLP, is the paper that makes practice legal. It is a temporary permit. It lets you drive a commercial vehicle on public roads while you learn. It is not a license. You cannot drive for pay on your own with it.
You earn the permit with a written test. You must pass the General Knowledge test first. That test covers the basics of commercial driving. It asks about inspection, stopping distance, and space management, which means keeping room around your truck. The state wants proof you know the rules first, because the truck weighs as much as a house. Your training truck may have air brakes, or it may pull a trailer. If so, you take those knowledge tests up front too. The permit has to match the vehicle you will sit in.
Once you have the permit, a clock starts. You must hold the CLP at least 14 days before the skills test, which is the driving test. Seat time matters, just like time on the bike. Two weeks is the minimum, and most learners need more. Use it to practice inspections, backing, and road miles. New Class A and Class B applicants have one more step. They must finish entry-level driver training, called ELDT. It comes from a provider on the federal training registry, a national list of approved schools. The provider reports that you finished, and the state checks before it lets you test.
The biggest permit rule is the person beside you. Whenever you drive, a CDL holder must sit in the front passenger seat. In a bus, that person may sit right behind you. Their license must cover that class of vehicle. They are your legal supervisor, like the parent beside the bike, ready to take over. Endorsements on a CLP are limited. An endorsement is a letter that allows a special kind of driving. You can usually hold passenger and school bus endorsements on the permit. But you cannot carry passengers other than your trainer and examiners. You cannot get a tank endorsement with anything in the tank. You cannot get a hazmat endorsement at all. Those wait for the full license.
A CLP needs the same medical certificate as a CDL, so yours must already be on file. The permit is good for a limited time, and your state's CDL manual says how long. Treat it as a countdown. Book your skills test as soon as the 14 days are behind you.
Worked example
Priya enrolls at a registered training school in Georgia to earn a Class A CDL. On her first Monday she takes the General Knowledge, Air Brakes, and Combination Vehicles knowledge tests at the licensing office and passes all three. She also has her medical certificate on file, so the clerk issues her Commercial Learner's Permit that same day. She writes the date on the permit and counts forward 14 days to find the earliest day she could legally test.
Over the next few weeks Priya drives the school's tractor-trailer every day with her instructor, who holds a Class A CDL, sitting in the passenger seat. She practices straight-line backing, offset backing, and the alley dock in the yard, then runs the on-road route through town. The school reports her entry-level driver training completion to the federal registry. On day 20, well past the minimum hold, she takes the skills test with the same instructor riding along to the site, passes, and trades her permit for a full Class A CDL.
