AB restrictions limit what you can drive, not whether you can drive
An AB restriction on your driver's license means you are not permitted to drive certain types of vehicles. The letter codes on your license — A, B, C, and so on — each refer to a specific vehicle class. If your license shows an AB restriction, it typically means you cannot operate vehicles in one or more of those categories, even though you hold a valid license.
The exact meaning of AB restrictions varies by state, because each state defines its own vehicle classes and restriction codes. In some states, an AB restriction might mean you cannot drive automatic transmission vehicles, or it might restrict you from driving vehicles over a certain weight. In others, it might prohibit towing or pulling a trailer. You need to check your specific state's driver's manual or contact your state's Department of Motor Vehicles to learn what AB means where you live.
Restrictions appear on your license card itself, usually printed in a small box or section labeled "Restrictions" or "Conditions." They are enforceable — driving a vehicle type you are restricted from operating can result in a ticket, fine, or license suspension, even if you are otherwise a safe driver.
Key Takeaways
- AB restrictions prevent you from driving certain vehicle types or classes, and the specific meaning depends on your state's vehicle classification system.
- You can see your restrictions printed on your physical license card in the restrictions or conditions section.
- Violating a restriction by driving a prohibited vehicle type is a traffic violation that can result in fines or license suspension.
- You can request a restriction be removed by taking a road test in the vehicle class you want to drive, or by meeting other state-specific requirements.
- Some restrictions are temporary and expire after a set period; others remain until you take action to remove them.
How AB restrictions get placed on your license
Restrictions are usually added to your license during the licensing process itself, not after you receive it. If you took your road test in an automatic transmission vehicle, for example, some states will restrict you from driving manual transmission vehicles until you pass another test in a manual car. If you took your test in a smaller vehicle, you might be restricted from driving larger trucks or vehicles that require a commercial license.
Restrictions can also be added if you fail part of the road test or if you pass with conditions — for instance, if you passed but the examiner noted that you struggled with a particular skill. In that case, the state may restrict you from certain driving situations until you demonstrate you can handle them safely.
Age-related restrictions are another common source. New drivers under a certain age (often 18 or 21, depending on the state) may receive restrictions on nighttime driving, passenger limits, or phone use. These restrictions typically expire automatically on your birthday or after a set number of months.
Common AB restriction codes and what they mean
Because each state has its own system, there is no single national meaning for AB restrictions. However, some patterns appear across multiple states. In many places, restrictions are labeled with single letters or letter combinations that correspond to vehicle classes or driving conditions.
A restriction might mean you cannot drive a manual transmission vehicle, or it might mean you cannot drive vehicles over a certain gross vehicle weight rating (GVWR). Some states use restrictions to limit you to daylight driving only, or to prohibit highway driving. Others restrict you from towing a trailer, or from carrying passengers under a certain age.
The only way to know what your specific restriction means is to check your state's driver's manual, look at the legend printed on the back of your license card, or contact your state's DMV directly. Do not assume — a restriction you do not understand is still enforceable, and ignoring it can result in a traffic citation.
How to remove an AB restriction
The process for removing a restriction depends on what the restriction is and why it was placed. For restrictions based on the vehicle you used during your road test, you typically need to take another road test in the vehicle class you want to drive. For example, if you were restricted because you tested in an automatic, you would take a new road test in a manual transmission vehicle.
For age-related restrictions, you usually do not have to do anything — they expire automatically when you reach the required age or after the specified time period. Your license will be updated automatically, or you may receive a new license in the mail.
For restrictions placed because you failed or struggled with part of the test, you may need to retake the full road test, or your state may allow you to take a shorter test focused on the skill you struggled with. Contact your state's DMV to find out what your specific restriction requires and what steps you need to take to remove it.
Some states charge a fee to retake the road test or to issue a new license without the restriction. Others do not. Check your state's DMV website or call their customer service line to learn the cost and process in your state.
What happens if you drive with a restriction you do not have
Driving a vehicle type that your license restricts you from operating is a traffic violation. An officer who stops you and discovers the violation can issue you a citation, which typically results in a fine. The amount varies by state and by the specific restriction violated.
In some cases, violating a restriction can also result in points on your driving record, which can raise your insurance rates or lead to license suspension if you accumulate too many points. Repeat violations or serious violations may result in license suspension or revocation.
The safest approach is to take your license restrictions seriously. If you are unsure what you are restricted from driving, do not drive that vehicle type until you have confirmed with your state's DMV. If you want to drive a vehicle you are currently restricted from, go through the process to have the restriction removed rather than risk a violation.
Restrictions versus endorsements
It is straightforward to confuse restrictions with endorsements, but they work in opposite directions. A restriction tells you what you cannot do; an endorsement tells you what you are additionally permitted to do. For example, you might have a motorcycle endorsement, which means you are permitted to ride a motorcycle in addition to driving a regular car. You might also have a restriction that prevents you from driving a manual transmission vehicle.
Both appear on your license, and both are enforceable. When you renew your license or explore for a new one, you can request that endorsements be added or that restrictions be removed, but the processes are different. Endorsements usually require passing an additional test; restrictions are usually removed by passing a test in the vehicle class you want to drive.
Frequently Asked Questions
Can I drive a vehicle that my restriction prohibits if someone else is in the car with a license to drive it?
No. A restriction on your license applies to you personally, regardless of who else is in the vehicle. If you are behind the wheel, you cannot drive a vehicle type your license restricts you from operating. The other person's license does not override your restriction.
Do AB restrictions show up on my driving record when I explore for insurance?
Yes. Insurance companies can see your license restrictions, and some restrictions may affect your rates or coverage. For example, if you are restricted from driving manual transmission vehicles but you insure a manual car, the insurance company may deny coverage or charge a higher rate. Always tell your insurance company about your restrictions when you get a quote.
If I move to a different state, do my restrictions transfer?
No. When you move and get a license in a new state, that state issues you a new license based on its own rules and vehicle classification system. Your old restrictions do not automatically carry over. However, if you took your road test in a specific vehicle type in your previous state, you may face the same restriction in your new state if you do not take a new test in the vehicle class you want to drive.
How long does it take to remove a restriction?
If you are removing a restriction by taking a road test, you can usually schedule the test within a few weeks. Once you pass, the restriction is removed when ready or within a few days, depending on your state. Age-related restrictions expire automatically on the date specified, with no action needed on your part.
What if I was restricted by mistake?
Contact your state's DMV and explain the situation. Bring documentation of your road test and any other relevant paperwork. The DMV can review your case and may remove the restriction if it was placed in error. If they confirm the restriction was a mistake, you may be able to get a corrected license without taking another test.
