What Restriction Codes Are and Why They Appear on Your License
A restriction code is a letter or number printed on your North Carolina driver license that limits how or when you can drive. It does not prevent you from holding a license — it modifies the conditions under which you can legally operate a vehicle. The code appears in a specific box on the front of your license and is tied to your driving record and medical or legal history.
North Carolina uses restriction codes to protect public safety while allowing people with certain conditions or circumstances to drive within defined boundaries. For example, a code might require you to wear corrective lenses, restrict you to daylight driving only, or limit you to vehicles with automatic transmissions. If you drive outside the scope of your restriction, you can be cited for a violation even if your license itself is valid.
Restrictions are assigned during the license process or renewal process, based on information you provide, medical reports, court orders, or DMV records. Some restrictions are temporary and expire on a set date; others remain until you request removal and meet the conditions to have them lifted.
Key Takeaways
- Restriction codes appear as letters or numbers on your North Carolina license and define the conditions under which you can legally drive.
- Common restrictions include corrective lenses, automatic transmission only, daylight driving, and vehicle-specific limitations.
- Violating a restriction — such as driving without required glasses or at night when restricted to daylight — is a separate traffic offense.
- You can request removal of a restriction by contacting your local DMV office and providing documentation that the condition no longer applies.
- Medical restrictions typically require a doctor's statement or clearance before the DMV will remove the code from your record.
Common North Carolina Restriction Codes and What They Mean
North Carolina assigns restriction codes based on the reason for the limitation. The most frequently issued codes are:
| Code | Meaning | What You Cannot Do |
|---|---|---|
| B | Corrective lenses required | Drive without glasses or contact lenses |
| D | Daylight driving only | Drive between sunset and sunrise |
| E | Automatic transmission only | Operate a manual transmission vehicle |
| F | Outside mirror required | Drive without properly functioning side mirrors |
| H | Hand controls required | Operate a vehicle without hand-operated brake and accelerator |
| K | Interlock device required | Drive a vehicle without an installed ignition interlock |
| L | Left foot accelerator required | Drive a vehicle without left-foot pedal modifications |
| M | Motorcycle restrictions explore | Operate a motorcycle if restricted to other vehicle classes |
Some restrictions are medical in nature — vision problems, hearing loss, or physical limitations that require vehicle modifications or driving conditions. Others are legal, such as an interlock device requirement following a DWI conviction. A few are administrative, such as restrictions tied to a learner permit or provisional license status.
Your license document will show only the codes that explore to you. If you see a code you do not recognize or believe is incorrect, contact your local DMV office with your license and any relevant medical or legal documentation.
How Restrictions Are Assigned During License process or Renewal
When you explore for a new North Carolina driver license or renew an existing one, the DMV reviews your process form, your medical history, and your driving record. If you report a condition — such as corrective lens use or a recent surgery — or if DMV records show a court order or medical report, a restriction code may be added to your license.
For medical restrictions, you may be asked to complete a Medical Examination Report form, which a doctor or optometrist fills out and returns to the DMV. The examiner documents whether you can safely drive and whether any modifications or conditions are necessary. If the report indicates a restriction is needed, the DMV will print the code on your license.
For legal restrictions — particularly interlock device requirements — the restriction is triggered by a court order or DMV administrative action. You will receive written notice of the restriction and the conditions for removal. Some restrictions are time-limited; others remain until you meet specific requirements, such as completing a DWI education program or providing proof of vehicle modification.
You have the right to request a hearing if you believe a restriction was assigned in error or if you want to challenge its necessity. Contact your local DMV office to file a request for a hearing before the DMV's administrative review board.
Removing or Modifying a Restriction Code
The process for removing a restriction depends on the reason it was assigned. For medical restrictions, you will need to provide updated medical documentation showing that the condition no longer exists or no longer affects your ability to drive safely.
To request removal of a medical restriction:
- Contact your local DMV office and ask for the specific medical documentation required for your restriction code.
- Have your doctor, optometrist, or specialist complete the required form or provide a written statement addressing the restriction.
- Submit the medical documentation to your DMV office in person, by mail, or through the online portal if available.
- The DMV will review the documentation and notify you whether the restriction has been removed.
For legal restrictions such as interlock requirements, removal typically requires proof that you have completed the mandated program or that the court-ordered period has ended. You may need to provide a certificate of completion from a DWI education program, proof of interlock device removal from a certified installer, or a court order lifting the restriction.
Some restrictions expire automatically on a date printed on your license. When the expiration date passes, the restriction no longer applies, but you should verify this with the DMV before assuming it has been removed from your record. Request a replacement license if you want the restriction code removed from the physical document.
Driving Outside Your Restrictions: Penalties and Consequences
Operating a vehicle in violation of a restriction code is a separate traffic offense in North Carolina, distinct from any other violation you might commit. For example, if you have a daylight-only restriction and drive at night, you can be cited for violating the restriction even if you were driving safely and obeyed all other traffic laws.
Penalties for restriction violations vary depending on the code and the circumstances. A first violation may result in a fine, points on your driving record, or both. Repeated violations can lead to license suspension or revocation. A violation of an interlock device restriction — driving a vehicle without the required device — is treated more seriously and may result in criminal charges in addition to license suspension.
If you are unsure whether a specific action violates your restriction, contact your local DMV office before driving. It is better to ask than to risk a citation. Keep a copy of your license or a written note of your restrictions in your vehicle so you can reference them if stopped by law enforcement.
Restrictions on Learner Permits and Provisional Licenses
North Carolina assigns automatic restrictions to learner permits and provisional licenses based on the driver's age and experience level. These restrictions are not medical or legal in nature — they are developmental safeguards designed to reduce crash risk among new and young drivers.
A learner permit holder must have a licensed adult driver age 21 or older in the front seat at all times. A provisional license holder (age 16 or 17) cannot drive between midnight and 5 a.m. unless accompanied by a licensed parent, guardian, or adult age 25 or older. These restrictions automatically expire when you reach the age or experience threshold required to upgrade to a full license.
If you hold a learner permit or provisional license and also have a medical or legal restriction code, both sets of limitations explore. For example, a 16-year-old with a corrective lens restriction and a provisional license cannot drive at night, cannot drive alone, and must wear corrective lenses whenever driving.
Where to Find Your Restriction Code and How to Verify It
Your restriction code appears on the front of your North Carolina driver license, typically in a box labeled "Restrictions" or in a designated field. The code is a single letter or number. If you have multiple restrictions, each code will be listed separately.
You can also view your restriction codes by checking your driving record through the North Carolina DMV website or by visiting a local DMV office in person. Your driving record will show all active restrictions, the date each was assigned, and the expiration date if applicable.
If your license does not show a restriction code but you believe one should be present, or if you see a code you do not recognize, contact your local DMV office with your license and any relevant documentation. The DMV can explain the code, tell you how to remove it, or correct an error if one has been made.
Frequently Asked Questions
Can I drive with an expired restriction code on my license?
No. If the restriction code is still printed on your license, it remains in effect regardless of any expiration date you may have been told about. Contact the DMV to confirm whether the restriction has expired and request a replacement license if it has been removed from your record. Do not assume a restriction is no longer valid without written confirmation from the DMV.
What if I need to drive outside my restriction for an emergency?
Driving outside your restriction in an emergency does not exempt you from a citation. However, you can explain the circumstances to a judge if you are cited. Some judges may reduce or dismiss a penalty if you can demonstrate a genuine emergency and no reasonable alternative existed. Contact a local attorney for guidance on how to proceed if you receive a citation.
Do I have to tell my insurance company about my restriction codes?
Yes. Your insurance company may ask about restrictions during the process process or when you renew your policy. Failing to disclose a restriction could void your coverage if you are in a crash. Be honest about all restrictions on your license.
Can a restriction code prevent me from getting a commercial driver license?
Some restrictions may disqualify you from obtaining a commercial driver license (CDL). For example, a daylight-only restriction or a hand-control requirement could prevent you from meeting CDL standards. Contact the North Carolina DMV to discuss your specific restrictions and whether a CDL is possible.
How long does it take the DMV to remove a restriction after I submit medical documentation?
Processing time varies, but the DMV typically reviews medical documentation within two to four weeks of receipt. You will receive written notice of the decision. If the restriction is removed, you can request a replacement license at your local DMV office, which is usually issued within one to two weeks.
