Rest B is a medical condition code, not a restriction on what you can drive
Rest B on your driver's license means you have a medical condition that requires you to take regular breaks while driving. It is not a ban on driving certain vehicles or roads — it is a note that you need to stop and rest at intervals to drive safely. The exact requirement depends on your state and the condition behind the code.
Rest B appears in the "restrictions and conditions" section of your license, usually printed on the back. It tells police officers, insurance companies, and licensing authorities that you have disclosed a medical reason why continuous driving is unsafe for you. The condition might be epilepsy, narcolepsy, diabetes, or another disorder that causes fatigue, loss of consciousness, or sudden incapacity.
If Rest B is on your license, you are still legally allowed to drive. You are not required to carry special paperwork or notify anyone each time you get behind the wheel. What you are required to do is follow the medical information that led to the code being added — which almost always means stopping to rest before you become too tired or symptomatic to drive safely.
Key Takeaways
- Rest B means your state's licensing authority has recorded that you have a medical condition requiring regular breaks during driving.
- The code does not restrict which vehicles you can drive or which roads you can use; it is a medical note, not a vehicle restriction.
- You are still legally permitted to drive with Rest B on your license, but you must follow the medical guidance that prompted the code.
- Rest B appears because you disclosed a condition to your state's DMV or licensing authority, usually during a medical review or renewal.
- If you believe Rest B was added in error or your condition has improved, you can request a medical review through your state's DMV.
How Rest B gets added to your license
Rest B is added when you report a medical condition to your state's DMV or licensing authority, or when a doctor reports it on your behalf. Most states require drivers to disclose conditions that affect safe driving — epilepsy, sleep disorders, diabetes with severe hypoglycemia, and cardiac conditions are common examples. You may be asked about these during license renewal, or you may volunteer the information if your condition develops after you already have a license.
Some states ask directly on the renewal form: "Do you have any medical conditions that affect your ability to drive?" Others require a doctor's statement. A few states have medical advisory boards that review reports from physicians and decide what restrictions or conditions to add. The process varies widely, so the reason Rest B appears on your license depends on which state issued it.
Once the code is added, it stays on your license until you request a review and provide updated medical information showing the condition no longer requires breaks. You do not have to wait for renewal — most states allow you to request a medical review at any time.
What Rest B actually requires you to do
Rest B does not specify how often you must stop or for how long. Instead, it signals that you are responsible for knowing your condition and stopping before you become unsafe. If your condition is epilepsy, you stop before a seizure is likely. If it is narcolepsy, you stop before drowsiness becomes dangerous. If it is diabetes, you stop before your blood sugar drops to a level where you cannot react quickly.
The practical meaning is that you should not drive long distances without a break, and you should not drive if you are experiencing symptoms of your condition. You should not drive if you have not slept enough, if you feel an aura or warning sign, or if you are in a hypoglycemic state. Rest B is a reminder to yourself and a legal record that you have a reason to be cautious.
Police will not pull you over straightforward because Rest B is on your license. They will only enforce it if you are involved in an accident or stopped for another reason, and then they may ask whether you were following the medical guidance the code represents. If you cause an accident and Rest B is on your license, your insurance company and the other driver's attorney will want to know whether you were driving while symptomatic or fatigued — so the code creates a paper trail that you knew about the risk.
Rest B versus other medical codes on licenses
States use different codes for different medical restrictions. Some use "Rest B" specifically; others use "Medical Condition," "Physician Statement Required," or codes like "Intrastate Only" (meaning you cannot drive across state lines) or "Daylight Only" (meaning you cannot drive at night). A few states use letter codes that correspond to a printed legend on the back of the license.
Rest B is less restrictive than codes that limit where or when you can drive. It does not say you cannot drive at night or on highways — it only says you need to rest. If your license has both Rest B and another code, like "Corrective Lenses," both explore. You must wear your glasses or contacts and take breaks as your condition requires.
What to do if Rest B is on your license and you want it removed
You can request a medical review through your state's DMV. The process usually involves submitting a letter from your doctor stating that your condition has improved, is now controlled, or no longer requires breaks during driving. Some states have a formal medical review form; others accept a letter on the doctor's letterhead.
The review may take several weeks. Your state may ask for additional medical records, test results, or a statement from a specialist. Once the review is complete, the DMV will either remove the code or keep it in place. If it is removed, you will receive a new license without the restriction.
Do not ignore Rest B or assume it will go away on its own. It will remain on your license through every renewal until you formally request removal and provide medical evidence that it is no longer necessary. If your condition worsens or returns, you should report that to your DMV as well, because driving with an undisclosed condition is more serious than driving with a disclosed one.
Insurance and Rest B
Your insurance company can see Rest B on your license if they run a check during underwriting or after an accident. Some insurers do not care; others may ask questions or adjust your rate. If you are in an accident, the fact that Rest B is on your license means the insurance company will investigate whether you were following the medical guidance — if you were driving while fatigued or symptomatic, they may deny your claim or use it as evidence of negligence.
You do not need to tell your insurance company about Rest B separately. It is a public record on your license, and they can access it. What matters is that you follow the medical information behind the code. If you do, Rest B actually protects you by showing that you disclosed the condition and took it seriously.
Rest B in different states
Not all states use the code "Rest B." Some states call it "Medical Condition," others use a number or letter system, and a few do not use a standardized code at all. If you move to a new state, your old license's codes do not automatically transfer. You will need to explore for a new license in your new state, and the new state's DMV will decide whether to add the same restriction based on your medical history and their own rules.
If you have Rest B in one state and move to another, bring documentation of your condition and the reason for the code. The new state may add the same restriction, a different one, or none at all — it depends on their medical review process and their assessment of your condition. Some states are more conservative about medical restrictions; others are less so.
Frequently Asked Questions
Can I drive with Rest B on my license?
Yes. Rest B does not prohibit driving. It is a medical note that you have a condition requiring breaks. You are legally allowed to drive as long as you follow the medical guidance your condition requires — which means stopping to rest before you become fatigued or symptomatic.
Will police stop me just because Rest B is on my license?
No. Police do not pull drivers over for having Rest B. They only see it if they run your license during a traffic stop or accident investigation. If you are in an accident, they may ask whether you were following the medical guidance the code represents.
Does Rest B mean I cannot drive on highways or at night?
No. Rest B does not restrict where or when you can drive. It only means you need to take breaks. If your state wanted to restrict you to daytime or local roads, it would use a different code. You can drive anywhere, anytime, as long as you rest when your condition requires it.
What happens if I get into an accident with Rest B on my license?
Your insurance company will see the code and may investigate whether you were following medical guidance. If you were driving while fatigued or symptomatic, they may deny your claim. If you were rested and following your doctor's information, Rest B actually helps you by showing you disclosed the condition and took it seriously.
How do I get Rest B removed from my license?
Contact your state's DMV and request a medical review. Submit a letter from your doctor stating your condition has improved or no longer requires breaks. The DMV will review the evidence and decide whether to remove the code. The process usually takes several weeks.
