Rest B is a medical restriction that limits when and how you can drive
Rest B is a restriction code that appears on your driver's license when your state's Department of Motor Vehicles has determined you need to rest before driving. It means you cannot drive for more than a certain number of hours without taking a break — typically you must rest for at least 15 minutes after every two hours of driving. The exact rules depend on your state, but the core idea is the same: the restriction exists because of a medical condition that makes fatigue dangerous.
Rest B does not mean you cannot drive at all. It means you must follow the rest requirement every time you get behind the wheel. If you ignore the restriction and are caught driving without taking the required breaks, you can be cited for violating your license conditions, which may result in a fine or suspension.
The restriction usually appears as a code on the back of your physical license card, alongside other restrictions like corrective lenses or automatic transmission only. When you renew your license, the restriction may be removed if your medical condition has improved, or it may stay if your doctor confirms you still need it.
Key Takeaways
- Rest B requires you to take a 15-minute break after every two hours of driving, though the exact duration varies by state.
- The restriction is placed on your license based on a medical evaluation, usually because of a condition that causes drowsiness or fatigue.
- You must follow the restriction every time you drive, or you risk a traffic citation and potential license suspension.
- The restriction is reviewed when you renew your license and may be removed if your medical condition improves.
- Rest B does not prevent you from driving — it only requires you to manage your driving time and take scheduled breaks.
Why Rest B appears on a license
Rest B is placed on your license when you have a medical condition that affects your ability to stay alert while driving. Common conditions that lead to this restriction include sleep apnea, narcolepsy, epilepsy, or other neurological disorders that cause sudden drowsiness or loss of consciousness. Your doctor may also recommend it if you take medications that cause fatigue or impair alertness.
The restriction is not punitive — it is a safety measure. Your state's DMV works with medical professionals to identify drivers who need extra protections to keep themselves and others safe on the road. Rest B gives you a way to continue driving while managing your condition through scheduled breaks.
In some cases, you may have requested the restriction yourself if you noticed you were becoming drowsy on long drives. In other cases, your doctor or a medical examiner may have flagged the condition during a medical review or after a traffic incident.
How to follow the Rest B restriction
Following Rest B is straightforward: after every two hours of continuous driving, you must stop and rest for at least 15 minutes. This means pulling over to a safe location — a rest area, parking lot, or other place where you can safely leave your vehicle — and taking a genuine break. Sitting in traffic does not count as driving time for this purpose; only active driving on the road counts toward your two-hour window.
The break itself should be used to rest, not to run errands or do other activities that keep you mentally engaged. Step out of the car, stretch, get some air, or sit quietly. The goal is to give your body and mind a chance to recover before you resume driving.
If you are on a long road trip, plan your route with rest stops in mind. Many highways have marked rest areas every 50 to 100 miles, which gives you a natural place to stop. If you are driving in an urban area or on local roads, you may need to plan stops at parking lots or other safe locations.
What happens if you drive without following Rest B
If you are stopped by a police officer and they discover you have violated your Rest B restriction, you can be cited for driving in violation of your license conditions. This is typically treated as a traffic violation, not a criminal offense, but it still carries consequences. You may receive a fine, points on your driving record, or both.
A violation can also affect your insurance rates and may lead to license suspension if you accumulate multiple violations. More importantly, driving without the required rest increases your risk of a crash caused by fatigue, which could injure or kill you or someone else.
If you find it difficult to follow the restriction — for example, if your job requires long hours of driving without breaks — talk to your doctor about whether the restriction is still necessary or whether there are other options. Do not straightforward ignore the restriction and hope you do not get caught.
Renewing your license with Rest B
When your license is up for renewal, you will need to go through the renewal process at your state's DMV. If you have a Rest B restriction, the DMV will check whether it should remain on your new license. This usually involves a medical review or a letter from your doctor confirming that your condition still requires the restriction.
If your medical condition has improved or resolved, your doctor can provide documentation stating that the restriction is no longer necessary. You can then request that the DMV remove it from your renewed license. If your condition has not changed, the restriction will carry over to your new license automatically.
Some states require you to renew your medical certification more frequently if you have a Rest B restriction — for example, every two years instead of every five or eight years. Check with your state's DMV to find out what the renewal schedule is for your situation.
Removing Rest B from your license
To remove Rest B from your license, you need to show that your medical condition no longer requires the restriction. This typically means getting a letter or medical certification from your doctor stating that you no longer experience the fatigue, drowsiness, or other symptoms that led to the restriction in the first place.
Once you have the medical documentation, take it to your state's DMV along with your current license. The DMV will review the paperwork and, if it is satisfactory, will remove the restriction from your license. You may be able to do this during a routine renewal, or you may need to visit the DMV in person to request an update.
If your condition is manageable with medication or treatment, your doctor may be willing to certify that you are safe to drive without the restriction. For example, if you have sleep apnea and are now using a CPAP machine consistently, your doctor may determine that the restriction is no longer needed.
Rest B versus other driving restrictions
Rest B is one of many restrictions that can appear on a driver's license. Other common restrictions include corrective lenses (you must wear glasses or contacts), automatic transmission only (you cannot drive a manual transmission vehicle), or daylight driving only (you cannot drive at night). Each restriction addresses a specific safety concern related to your medical condition or driving ability.
Some restrictions are temporary — for example, if you have a broken arm and cannot safely operate a manual transmission, the restriction may be removed once you have healed. Other restrictions, like Rest B, may be long-term if your medical condition is chronic. The key is that all restrictions are designed to keep you and others safe while still allowing you to drive.
If you are unsure what any restriction on your license means, contact your state's DMV or ask your doctor. Do not guess or ignore a restriction you do not understand.
Frequently Asked Questions
Does Rest B mean I cannot drive at night?
No. Rest B only requires you to take a 15-minute break after every two hours of driving. It does not restrict the time of day you can drive. However, if you have a separate nighttime restriction on your license, that would be listed separately.
Can I get a Rest B restriction removed before my license renewal?
Yes. If your doctor certifies that your medical condition has improved and the restriction is no longer necessary, you can request an update at your state's DMV. You do not have to wait until your license renewal date.
What if I fall asleep while driving despite the Rest B restriction?
If you fall asleep at the wheel, pull over when ready at the next safe location and rest until you are fully alert. If you are unable to stay awake even with the required breaks, talk to your doctor — your condition may need different treatment or your restriction may need to be more severe.
Does Rest B appear on my license card or only in the DMV system?
Rest B typically appears as a code on the back of your physical license card, so police officers can see it during a traffic stop. It is also recorded in the DMV system.
Can I drive for a job that requires long hours if I have Rest B?
You can drive for work, but you must follow the Rest B restriction — taking a 15-minute break after every two hours of driving. If your job requires more than two hours of continuous driving without breaks, you may need to discuss this with your employer and your doctor to find a solution.
