What restriction codes on your license mean

A restriction code is a letter or number printed on your driver's license that tells police, employers, and insurance companies what you are not permitted to do while driving. The code itself does not prevent you from driving — it is a legal record that you must follow certain rules. If you violate a restriction, you can be cited even if you would normally be allowed to perform that action.

Restriction codes are set by your state's Department of Motor Vehicles (or equivalent agency) and appear on the front or back of your physical license. Each state uses its own code system, so a code that means one thing in California means something different in Texas. The restrictions are usually added when you renew your license, fail a vision or medical test, or have a conviction that requires them.

You can see your restriction codes by looking at your license card itself — they are typically listed under a section labeled "Restrictions" or "Codes" — or by logging into your state's DMV online portal if it offers one. If you do not understand what a code means, your state's DMV website publishes the full list, or you can call your local DMV office and ask them to explain it.

Key Takeaways

  • Restriction codes are letters or numbers on your license that specify what you cannot do while driving, and violating them can result in a citation.
  • Each state has its own code system, so you must check your state's DMV guide to learn what your specific codes mean.
  • Common restrictions include corrective lenses, hearing aids, automatic transmission only, and no commercial driving.
  • Restrictions are added by the DMV when you renew, fail a medical or vision test, or have a conviction that requires them.
  • You can remove most restrictions by retesting, getting medical clearance, or completing a required course, depending on the reason the restriction was added.

Common restriction codes and what they require

The most frequent restrictions across all states involve vision and medical equipment. Code B or similar typically means you must wear corrective lenses (glasses or contacts) every time you drive. Code D usually means you must wear a hearing aid. Some states use code E for automatic transmission only, meaning you cannot drive a manual or standard-shift vehicle. Code F often restricts you to daylight driving only.

Other common codes restrict the type of vehicle you can operate. Code J might mean no commercial vehicles, or it might mean no vehicles over a certain weight. Some states add a code if you are restricted to in-state driving only, or if you cannot drive on interstate highways. A few states use codes to indicate that you must display a medical alert placard or that you have a conditional license (one that expires sooner than normal).

The only way to know what your specific codes mean is to consult your state's DMV handbook or restriction code guide. These are usually available as a PDF on the DMV website, or you can request a printed copy. If your state's website does not list the codes clearly, call the DMV directly — they can read your license and explain each restriction in plain language.

Why the DMV adds restrictions to your license

The most common reason for a restriction is a failed vision or hearing test during renewal. If you cannot read the eye chart to the standard your state requires, the DMV will add a corrective lens restriction. If you fail a hearing test (required in some states), a hearing aid restriction is added. These are safety measures — the DMV is documenting that you have a condition that requires correction to drive safely.

Medical conditions can also trigger restrictions. If your doctor reports to the DMV that you have a seizure disorder, severe arthritis, or another condition that affects your ability to control a vehicle, the DMV may add restrictions such as daylight driving only or automatic transmission only. Some states require doctors to report certain conditions; others rely on self-reporting by the driver.

Convictions can result in restrictions as well. A conviction for driving under the influence (DUI) often comes with a restriction on the type of vehicle you can drive or a requirement to install an ignition interlock device. Some states add restrictions after multiple traffic violations or after a suspension is lifted. In these cases, the restriction is part of your sentence or the condition of license reinstatement.

How to find out what your restriction codes mean

Start by looking at your physical license card. Restrictions are usually listed in a box or section near the bottom or back of the card, often labeled "Restrictions," "Codes," or "Conditions." Write down the exact letters or numbers you see.

Next, go to your state's DMV website and search for "restriction codes" or "license codes." Most states publish a table or guide that matches each code to its meaning. If your state does not have this online, call your local DMV office with your license number and restriction codes, and they will tell you what each one means. You can also visit a DMV office in person and ask a clerk to explain them.

If you received your restriction recently and do not understand why, check the paperwork that came with your renewed license or the notice from the DMV. It should explain the reason. If it does not, contact the DMV and ask — they have a record of why the restriction was added.

How to remove or modify a restriction

The process depends on why the restriction was added. If it was added because you failed a vision test, you can remove it by passing a vision test again. Schedule a vision screening at your DMV or with an eye doctor (if your state accepts outside exams), pass the test, and bring the results to the DMV when you renew. The restriction will be removed from your new license.

For medical restrictions, you typically need a letter from your doctor stating that your condition has improved or is now controlled. For example, if you have a daylight-only restriction due to poor night vision, your eye doctor can test you again and write a letter saying your vision now meets the standard. Bring this letter to the DMV and request that the restriction be removed. The DMV will review it and may remove the restriction or require you to pass a test.

If the restriction was added because of a conviction, removal depends on the sentence. Some restrictions are automatic — they expire after a set time (for example, one year after a DUI conviction). Others require you to complete a course, pay a fee, or meet other conditions. Check the court paperwork or call the court that handled your case to learn what you must do. Once you have completed the requirements, contact the DMV and ask them to remove the restriction from your license.

For restrictions related to vehicle type (such as automatic transmission only), you can remove them by passing a driving test in a manual vehicle. Schedule a road test with your DMV, bring a manual vehicle, and demonstrate that you can operate it safely. If you pass, the restriction will be removed at your next renewal.

Restriction codes versus suspensions and revocations

A restriction is different from a suspension or revocation. A restriction means you can still drive, but only under certain conditions. A suspension means your license is temporarily invalid — you cannot drive at all until the suspension is lifted. A revocation means your license has been permanently cancelled and you must reapply for a new one (which may take months or years).

Restrictions appear on your active license. Suspensions and revocations are recorded in the DMV database, and if you try to drive during a suspension or revocation, you can be charged with driving with a suspended or revoked license — a criminal offense in most states. If you are unsure whether your license is restricted, suspended, or revoked, check your state's DMV website (most have a "check license status" tool) or call the DMV directly.

What happens if you violate a restriction

Violating a restriction is a traffic violation. For example, if you have a corrective lens restriction and drive without glasses, or if you have an automatic-transmission-only restriction and drive a manual vehicle, you can be cited by police. The citation is typically a misdemeanor or infraction, depending on your state and the specific restriction.

Penalties vary by state but usually include a fine, points on your driving record, and possible license suspension. Some violations carry higher penalties than others — for example, violating a daylight-only restriction by driving at night may result in a larger fine than violating a corrective lens restriction. If you receive a citation for violating a restriction, you have the right to contest it in traffic court.

If you believe a restriction on your license is incorrect or no longer applies to you, do not ignore it or violate it. Instead, contact the DMV and request a review. Explain why you believe the restriction should be removed, provide any supporting documentation (such as a doctor's letter), and ask the DMV to reconsider. This is faster and safer than risking a citation.

Frequently Asked Questions

Can I drive if I have a restriction code on my license?

Yes, you can drive, but only within the limits of your restriction. If your restriction is corrective lenses, you can drive as long as you wear glasses or contacts. If it is automatic transmission only, you can drive any automatic vehicle but not a manual one. Violating the restriction is a traffic violation.

Do restriction codes affect my insurance rates?

Restrictions themselves do not usually affect rates, but the reason for the restriction might. For example, if you have a restriction because of a DUI conviction, your insurance rates will be higher because of the conviction, not because of the code. Tell your insurance company about your restrictions when you get a quote or renew your policy.

What if I move to a different state — do my restriction codes transfer?

No. When you get a license in a new state, the new state's DMV will issue a new license with its own codes based on its own system. You will need to pass any required tests (vision, written, road) and report any medical conditions to the new state. The new state may or may not add restrictions, depending on its rules and your situation.

How long does a restriction stay on my license?

It depends on the reason. Medical or vision restrictions stay until you pass a retest or get medical clearance. Restrictions from a conviction stay for the length of time ordered by the court — this could be one year, five years, or longer. Some restrictions expire automatically; others require you to request removal once you have met the conditions.

Can I get a temporary license without restrictions while I wait for mine to be updated?

No. Your current license is valid even with restrictions, and you must follow those restrictions. If you need the restriction removed, work with the DMV on the process — vision retest, medical letter, or court paperwork — rather than waiting for a temporary license. Most states do not issue temporary licenses for restriction changes.
