What restriction codes on your Ohio license mean

A restriction code on your Ohio driver license is a letter or number printed on the front or back that limits what you can drive or how you can drive it. The code itself — like "B" or "E" — is shorthand for a specific rule. For example, restriction "B" means you must wear corrective lenses (glasses or contacts) whenever you drive. Restriction "E" means you can only drive an automatic transmission vehicle.

Restrictions are placed on your license during the issuance or renewal process, usually because of a medical condition, a vision problem, or the type of vehicle you were tested in. They stay on your license until you renew it and either pass a new test or have a doctor clear you. If you drive in violation of a restriction — for instance, driving without the glasses your "B" restriction requires — you can be cited, even if you were otherwise driving safely.

The Ohio Bureau of Motor Vehicles (BMV) assigns these codes based on information from your eye exam, your medical history, or the results of your road test. Understanding what your code means helps you know what you are legally allowed to do behind the wheel.

Key Takeaways

  • Restriction codes are single letters or numbers on your Ohio license that limit what vehicle you can drive or how you must drive it.
  • Common restrictions include "B" for corrective lenses, "E" for automatic transmission only, and "H" for hearing aid use.
  • You receive a restriction code during your license test or renewal if the BMV determines you need one based on vision, medical, or vehicle-type factors.
  • Driving in violation of a restriction code can result in a traffic citation even if your driving was otherwise safe.
  • You can request removal of a restriction by passing a new test, obtaining medical clearance, or renewing your license with updated information.

Common Ohio restriction codes and what they require

The most frequently assigned restriction codes in Ohio are tied to vision and vehicle type. Restriction "B" requires corrective lenses — you must wear glasses or contacts every time you drive. This code is issued when your vision test shows you need correction to meet the legal standard. Restriction "C" means you must wear corrective lenses and also restricts you to daylight driving only; it is less common but may be assigned if your vision is corrected but still limited in low light.

Restriction "E" limits you to automatic transmission vehicles. You receive this code if you took your road test in an automatic car and did not demonstrate the ability to operate a manual transmission. Restriction "H" requires you to wear a hearing aid while driving, issued when your hearing test shows you need one to drive safely. Restriction "K" means you cannot drive a commercial vehicle, even if you hold a commercial license class.

Restriction "N" limits you to vehicles equipped with an ignition interlock device — a breath-testing device that prevents the engine from starting if alcohol is detected. This code is mandatory for drivers convicted of driving under the influence (DUI) in Ohio. Restriction "X" means you cannot operate a vehicle with air brakes, typically assigned to drivers who did not pass the air brake portion of a commercial driving test.

How restriction codes are assigned during your license test

When you take your Ohio driver license test, the BMV examiner notes the type of vehicle you used and observes how you handle it. If you take your test in an automatic transmission car, you will receive restriction "E" unless you specifically request and pass the test in a manual transmission vehicle. This is why some drivers choose to test in a manual car — to avoid the restriction and keep the option to drive either type of vehicle.

Before your test, you also take a vision screening. If your vision does not meet the standard without correction, the examiner will note that you need glasses or contacts, and restriction "B" will be added to your license. If your corrected vision still falls short of the standard, or if the examiner has concerns about your ability to see in low light, restriction "C" may be assigned instead.

Medical conditions reported on your process can also trigger restrictions. If you disclose a hearing impairment, the BMV may require a hearing test and assign restriction "H" if you need a hearing aid. If you have a DUI conviction, restriction "N" (ignition interlock) is mandatory and will be placed on your license as part of the sentencing requirement.

Removing or changing a restriction code

The path to removing a restriction depends on the type of code and why it was assigned. For vision-related restrictions like "B" or "C", you can request removal by passing a new vision test that shows your uncorrected vision now meets the standard, or by having an eye doctor submit a letter confirming your vision is adequate without correction. You do not have to wait until your license renewal; you can visit an Ohio BMV office at any time to request a vision retest.

For restriction "E" (automatic transmission only), you must pass your road test in a manual transmission vehicle. Schedule a test appointment, bring a manual car, and demonstrate that you can operate it safely. Once you pass, the restriction is removed and your license is updated. Some BMV locations may issue a temporary document on the spot; others may mail your updated license within a few business days.

For restriction "H" (hearing aid), you can request removal by providing medical documentation that your hearing has improved or that you no longer need the device. For restriction "N" (ignition interlock), removal is governed by your DUI sentence and the court that imposed it — you cannot remove it yourself. You must follow the terms of your sentence and request removal through the court or your probation officer once you have met the requirements.

At any license renewal, you have the chance to update your information. If your medical condition has changed, your vision has improved, or you want to challenge a restriction, bring supporting documentation (such as a new eye exam or a doctor's letter) to your renewal appointment. The BMV will review it and may remove the code if the evidence supports it.

What happens if you drive in violation of a restriction

Driving in violation of a restriction code is a traffic offense in Ohio. If you are stopped and the officer sees that your license carries restriction "B" but you are not wearing glasses, you can be cited for that violation alone, regardless of how safely you were driving. The citation is separate from any other traffic charge and can result in a fine, points on your driving record, and potential license suspension if you accumulate too many violations.

For restriction "E", driving a manual transmission vehicle when your license is restricted to automatic is also a violation. For restriction "N" (ignition interlock), operating a vehicle without the device installed, or tampering with it, is a serious offense that can result in criminal charges in addition to license suspension.

The consequences build over time. A single violation may result in a fine of $100 to $300 and two to four points on your record. Multiple violations can lead to license suspension. If you have a restriction you believe is no longer necessary, it is far safer and cheaper to go through the process of removing it than to risk being cited.

Restriction codes and vehicle type or class

Some restriction codes are tied to the class of license you hold. Restriction "K" appears on commercial driver licenses (CDL) and means you cannot operate a commercial vehicle, even though you hold a CDL. This code is assigned when you fail the commercial driving test but pass the regular passenger vehicle test, or when you have a medical condition that disqualifies you from commercial driving but not from driving a personal vehicle.

Restriction "X" (no air brakes) is also specific to commercial licenses. If you take your CDL test in a vehicle without air brakes and do not pass the air brake component, restriction "X" is added. You can drive a commercial vehicle with this restriction, but only one without air brakes. To remove it, you must pass the air brake test in a vehicle equipped with air brakes.

If you hold a regular (non-commercial) license, you will not see restrictions "K" or "X". Your restrictions will be limited to those that explore to passenger vehicles, such as "B" (corrective lenses), "E" (automatic transmission), or "H" (hearing aid).

How to check your restriction codes

Your restriction codes are printed on the front of your Ohio driver license, usually in a small box labeled "Restrictions" or listed as a series of letters. You can see them every time you look at your license. If you want a detailed explanation of what each code means, the Ohio BMV website lists all restriction codes and their definitions, or you can call your local BMV office and ask.

If you are renewing your license online or by mail, you will receive a notice before your renewal that shows your current restrictions. If you believe a restriction is incorrect or should be removed, contact the BMV before you renew so you can bring the necessary documentation (such as an updated eye exam or medical letter) to support your request.

Frequently Asked Questions

Can I drive someone else's car if my license has restriction E?

No. Restriction "E" means you can only drive automatic transmission vehicles, regardless of whose car it is. Driving a manual transmission vehicle violates the restriction and can result in a citation. The restriction applies to you, not to the vehicle or the owner.

Do I have to renew my license to remove a restriction code?

No. You can visit an Ohio BMV office at any time to request a vision retest (for restrictions "B" or "C"), a road test in a manual vehicle (for restriction "E"), or to submit medical documentation. You do not have to wait for your renewal date. However, if you do nothing, the restriction will remain on your renewed license.

What if I got restriction E because I tested in an automatic, but I can drive a manual?

You can remove it by scheduling a road test in a manual transmission vehicle and passing it. The test is the same as a regular road test; you just need to bring a manual car. Once you pass, the restriction is removed.

Is restriction N permanent?

No, but it is not removed by you alone. Restriction "N" (ignition interlock) is part of your DUI sentence. You must follow the court's requirements — which typically include installing and maintaining the device for a set period — and then request removal through the court or your probation officer. The BMV will remove it once the court notifies them that you have met the conditions.

Can I get a citation for a restriction code violation if I was not doing anything else wrong?

Yes. A restriction code violation is a separate offense. You can be cited for driving without the corrective lenses your "B" restriction requires, or for driving a manual car with restriction "E", even if your driving was otherwise safe and you were not speeding or breaking any other law.
