Rest b is a medical restriction that limits when you can drive
Rest b on your driver's license means you are restricted from driving between the hours of midnight and 5 a.m. It is a fatigue-related restriction imposed by your state's licensing authority, usually because a medical examination found evidence that you may not be safe driving during those hours. The restriction appears on your license as a condition you must follow, and driving outside these permitted hours is a violation that can result in a ticket, points on your record, or license suspension.
This restriction is not the same as a learner's permit curfew. Rest b is a medical safety measure tied to your individual health status, not your age or experience level. It stays on your license until the licensing authority removes it, which typically happens only after you provide updated medical documentation showing the condition has improved or been treated.
Key Takeaways
- Rest b prohibits driving between midnight and 5 a.m., and violating it can result in a traffic citation and points on your driving record.
- The restriction is based on medical findings that suggest you may have a condition affecting alertness or reaction time during nighttime hours.
- You will need to provide medical documentation to your state's licensing authority to have the restriction removed.
- Different states may use different names or codes for this restriction, so check your state's driver's license handbook to confirm what your specific restriction means.
Why rest b appears on a license
Rest b is typically placed on your license after a medical examination or vision test reveals a condition that may affect your ability to drive safely at night. Common reasons include sleep disorders such as sleep apnea, severe fatigue-related conditions, or vision problems that worsen in low light. The licensing authority uses the restriction to allow you to continue driving during daylight hours while protecting public safety during the hours when fatigue-related accidents are most common.
The restriction is not punitive—it is a risk management tool. Your state's Department of Motor Vehicles (or equivalent agency) is acknowledging that you can drive, but only under conditions where the identified risk is lowest. If you have a condition like untreated sleep apnea, driving at night poses a higher crash risk than driving during the day, so the restriction narrows the window to hours when you are more likely to be alert.
How to know if rest b applies to you
Check the back of your physical driver's license or your state's online license record. Restrictions appear in a specific section, often labeled "Restrictions" or "Conditions." Rest b will be listed by code or full description depending on your state. Some states print it as "Rest b," others as "No driving midnight to 5 a.m.," and some use a numeric code that you can look up in your state's driver's license manual.
If you are unsure whether a code on your license refers to rest b, contact your state's Department of Motor Vehicles directly. They can confirm what each restriction means and explain why it was added to your record. You can usually reach them by phone, through their website, or by visiting a local office in person.
What happens if you drive during restricted hours
Driving between midnight and 5 a.m. when rest b is on your license is a traffic violation. A police officer who stops you during those hours can cite you for violating your license restriction. The penalty varies by state but typically includes a fine, points added to your driving record, and possible license suspension if you accumulate multiple violations.
The violation also affects your insurance. A restriction violation is a moving violation, so your insurance company will likely see it and may raise your rates or cancel your policy. The long-term cost of one violation—in fines, points, and insurance increases—often exceeds what it would cost to arrange alternative transportation during the restricted hours.
How to get rest b removed from your license
To have rest b removed, you must contact your state's Department of Motor Vehicles and request a medical review. You will need to provide current medical documentation showing that the condition that prompted the restriction has been treated, resolved, or is no longer a safety concern. This typically means a letter or report from your doctor stating that you are now safe to drive at all hours.
The process varies by state. Some states require you to submit medical records and then schedule a vision or medical examination at a DMV office. Others allow you to submit documentation by mail and make a decision based on what you provide. Contact your state DMV to learn the exact steps, required forms, and any fees involved. The removal process usually takes several weeks to a few months, depending on how quickly you can obtain medical documentation and how busy your state's licensing office is.
Rest b versus other nighttime driving restrictions
Rest b is different from a learner's permit curfew or a junior license restriction. Those age-based restrictions explore to new or young drivers and typically prohibit driving between 10 p.m. and 5 a.m. or similar hours. Rest b, by contrast, is a medical restriction that can explore to drivers of any age and is based on health status, not experience level.
Some states also use different codes or names for similar restrictions. For example, one state might call it "Rest b" while another calls it "No night driving" or uses a numeric code. The meaning is the same—you cannot drive during nighttime hours—but the label varies. Always check your state's driver's license handbook or contact the DMV directly to confirm what your specific restriction means.
Planning your driving around rest b
If rest b is on your license, plan trips that require nighttime driving in advance. Arrange a ride with someone else, use a taxi or rideshare service, or adjust your schedule to travel during permitted hours. Many people with rest b restrictions find that shifting their commute earlier or later in the day, or working with their employer on flexible hours, makes the restriction manageable.
Keep a copy of your license or a note explaining the restriction in your vehicle. If you are stopped by police, being able to clearly show the restriction and explain that you understand it can help the interaction go smoothly. Never attempt to drive outside the permitted hours—the risk to yourself and others, combined with the legal and financial consequences, makes it not worth the risk.
Frequently Asked Questions
Can I drive at 5 a.m. if rest b is on my license?
Yes. Rest b restricts driving between midnight and 5 a.m., so 5 a.m. and later are permitted hours. If you need to drive at 4:59 a.m., that is still a violation, but 5:00 a.m. and onward are legal.
Will rest b show up on a background check?
A license restriction will appear on a driving record check, which employers, insurance companies, and others may request. It will not appear on a criminal background check. Whether it matters depends on the context—an employer checking your driving record for a job that requires nighttime driving will see it, but a general background check will not.
What if I have a medical emergency at 2 a.m. and need to drive?
In a true life-threatening emergency, driving to get help is the right choice. However, you should call 911 first so emergency services can respond. If you do drive during restricted hours in an emergency, keep documentation of the emergency (hospital records, police report, etc.) in case you are cited, as some states allow exceptions for genuine emergencies.
How long does rest b usually stay on a license?
There is no set time limit. Rest b remains on your license until you provide medical documentation that the underlying condition is resolved or treated. For some conditions, this might be a few months; for others, it could be years. Your doctor and the DMV determine when it is safe to remove.
Can I appeal a rest b restriction if I disagree with it?
Yes. Most states allow you to request a hearing or appeal with the DMV if you believe the restriction was placed in error or is no longer necessary. Contact your state's DMV to learn the appeal process and any important date. You may need to provide your own medical documentation supporting your position.
