Rest on a driver's license is a restriction code that limits when and how long you can drive before taking a mandatory break

When you see "Rest" printed on your driver's license, it means your state has imposed a rule about how many hours you can drive continuously before you must stop and rest. This is not a suggestion — it is a legal requirement tied to your license. The specific hours vary by state and sometimes by the type of vehicle you drive, but the core rule is the same: drive past the limit, and you are breaking the law.

Rest restrictions are most common on commercial driver's licenses (CDLs), though some states also explore them to certain non-commercial licenses. The restriction exists because fatigue is a documented safety hazard. A driver who has been behind the wheel for too long is more likely to cause an accident, and law enforcement can cite you for violating a rest restriction even if you have not crashed.

The restriction code itself appears as a letter or number on your license — often "R" or a similar designation — and the actual hours are listed in the conditions section or on a separate document your state DMV provides when you receive your license.

Key Takeaways

  • A rest restriction on your license means you must stop driving and rest after a set number of hours, usually between 8 and 12 hours depending on your state and license type.
  • Violating a rest restriction is a traffic violation that can result in a fine, points on your record, or suspension of your CDL.
  • Federal Hours of Service rules for commercial drivers are separate from state rest restrictions and often more stringent, so you must follow whichever is stricter.
  • You can request that a rest restriction be removed or modified if you can show the state that the restriction is no longer necessary for your situation.
  • Not all states use the same rest restriction codes or hours, so if you drive across state lines, you need to know the rules in each state where you hold a license.

Why a Rest Restriction Appears on Your License

A rest restriction is usually placed on your license for one of two reasons: either your state requires it as a standard condition for a certain class of license, or it was added because of a specific incident or medical condition in your driving history.

Some states impose rest restrictions on all CDL holders as a baseline safety measure. Others add them only to drivers who have been involved in fatigue-related accidents, who failed a medical exam, or who have a documented sleep disorder. A few states use rest restrictions for drivers over a certain age or for those renewing after a long period without a license.

If you are unsure why the restriction is on your license, your state's DMV can tell you. The reason matters because it affects whether you can request removal and what evidence you will need to provide.

How Rest Restrictions Work in Practice

The mechanics are straightforward: you drive for the number of hours your restriction allows, then you must stop and rest for a minimum period before you can drive again. Most rest restrictions require a break of at least 8 hours, though some states specify 10 or 12 hours depending on the type of driving you do.

The clock resets after your rest period. If your restriction says you can drive 10 hours before resting, you drive 10 hours, rest 8 hours, and then you can drive another 10 hours. Some states allow a shorter break — say 4 or 6 hours — if you are not driving commercially, but the rule still applies.

You are responsible for tracking your own hours. Law enforcement can ask to see your logbook or electronic records, and if you cannot show that you complied with your rest restriction, you can be cited. Fines vary by state but typically range from $100 to $500 for a first violation, with higher penalties for repeat offenses.

Rest Restrictions vs. Federal Hours of Service Rules

If you hold a CDL and drive commercially, you are subject to both your state's rest restriction and the federal Hours of Service (HOS) rules set by the Federal Motor Carrier Safety Administration (FMCSA). These are not the same thing, and you must follow whichever is stricter.

Federal HOS rules for most commercial drivers limit you to 11 hours of driving in a 14-hour window, with a mandatory 10-hour off-duty period before you can drive again. Some states have rest restrictions that are more restrictive than this — for example, requiring 12 hours of rest instead of 10. In that case, you follow your state's rule.

If your state's rule is less restrictive than federal HOS, federal rules take precedence. Your employer and your state's DMV both expect you to know which applies to you. Confusion between the two is a common source of violations.

How to Find Out What Your Rest Restriction Says

Your rest restriction should be printed on your physical license card or listed in the conditions section on the back. If it is not clear, or if you received your license years ago and do not remember the details, contact your state's DMV directly.

You can also request a copy of your driving record, which will list all restrictions and conditions. Most states allow you to order this online through their DMV website, by mail, or in person. The record usually arrives within one to two weeks and costs between $5 and $15.

If you drive in multiple states, check the rules for each state where you hold a license. A rest restriction in one state may not transfer to another, and some states have reciprocal agreements that recognize restrictions from other states while others do not.

Requesting Removal or Modification of a Rest Restriction

You can petition your state's DMV to remove or modify a rest restriction, but the process and the likelihood of success depend on why the restriction was placed on your license in the first place.

If the restriction was added because of a medical condition — such as sleep apnea or narcolepsy — you will typically need a letter from a physician stating that the condition has been treated and is no longer a safety concern. Some states require a formal medical evaluation by a state-approved examiner.

If the restriction was added after an accident or violation, you may need to show a clean driving record for a set period (often one to three years) before the DMV will consider removal. Some states allow removal after a certain number of years regardless of the reason, while others do not.

The request process varies by state. Some DMVs have a formal petition form; others require a letter. Contact your state's DMV licensing division to ask what documentation they need and what the timeline is. There is usually no fee, but the process can take several weeks to several months.

What Happens If You Violate a Rest Restriction

Driving past your rest restriction limit is a traffic violation. The consequences depend on your state and whether you are driving commercially, but they typically include a fine, points added to your driving record, and possible license suspension.

For CDL holders, a violation can also trigger a review of your medical certification and may result in additional restrictions being added to your license. If you are driving for an employer, the violation will likely appear on your motor vehicle record (MVR), which employers can see when they check your background.

A second or third violation within a certain period (usually five to ten years) can result in CDL suspension or revocation. Some states treat rest restriction violations as serious enough to warrant a mandatory court appearance.

If you are cited for a rest restriction violation, you have the right to contest it. You can argue that you did not violate the restriction, that the restriction itself is invalid, or that there were emergency circumstances. An attorney who specializes in traffic law can help you evaluate your options.

Frequently Asked Questions

Does a rest restriction mean I cannot drive at night?

No. A rest restriction limits total hours of driving in a 24-hour period, not the time of day you drive. You can drive at night as long as you stay within your total hour limit and take your required rest break. Some states have separate restrictions on night driving for certain license types, but those are different from a rest restriction.

If I have a rest restriction in one state, do I have to follow it in other states?

Yes. Your license and all its restrictions are valid in every state. If your license says you must rest after 10 hours of driving, that rule applies whether you are driving in your home state or across the country. However, you must also follow the rules of the state you are currently in, so if another state has a stricter rule, you follow that instead.

Can I get a rest restriction removed if I take a defensive driving course?

Defensive driving courses do not automatically remove a rest restriction. Removal depends on the reason the restriction was placed on your license. If it was added for a medical reason, you need medical documentation. If it was added after a violation, you typically need a clean driving record for a set period. Contact your state's DMV to ask what specific steps are required.

What is the difference between a rest restriction and a medical certification restriction?

A rest restriction limits driving hours. A medical certification restriction means you must pass a medical exam to keep your CDL valid. You can have both. A medical restriction does not automatically include a rest restriction, and vice versa, though they are sometimes added together if a medical condition affects your ability to drive safely.

Do I have to log my driving hours if I have a rest restriction?

If you drive commercially, yes — federal law requires you to keep a logbook or use an electronic logging device (ELD) regardless of whether you have a rest restriction. If you drive non-commercially, your state may not require a formal logbook, but you should still be able to show when you drove and when you rested if law enforcement asks.
