Can You Legally Sleep Overnight at a Highway Rest Area?

Many states allow tired drivers to sleep inside a legally parked car or RV at a highway rest area. That does not mean every state allows an eight-hour stay, and it rarely means travelers can turn a parking space into a campsite.

The difference can be substantial.

For example, California allows up to eight hours in a 24-hour period, while Pennsylvania permits sleeping in a parked vehicle but limits most rest-area visits to two hours. Tennessee prohibits overnight parking and limits stops to two hours.

Our review of current laws, administrative rules, and transportation-agency guidance found:

• Published language in 19 states supports a full-night rest inside the vehicle, although several impose an eight- to 24-hour limit.
• Another 14 states limit ordinary motorists to a short rest or bar overnight parking.
• Eight states rely heavily on the facility, road system, or posted sign.
• Nine states have no clear statewide public rule answering the question.

Those last nine states should not be treated as automatically permitting it. Posted signs can also impose a shorter limit than the general state rule.

Important: We checked the rules below on September 4, 2026. They cover ordinary travelers in cars and privately used RVs at state-operated highway rest areas. Toll-road plazas, commercial vehicles, local roads, and individual facilities may follow different rules. This guide addresses rest-area use, not local vehicle-dwelling ordinances.

Sleeping in Your RV Is Not Always Considered Camping

Several states distinguish between sleeping inside a parked vehicle and camping. Georgia law bans camping on transportation department property but preserves the temporary use of designated areas for resting and sleeping. Pennsylvania specifically allows sleep in a legally parked vehicle, even though its two-hour limit makes a full night impossible at most PennDOT rest areas.

Connecticut draws an even finer line. Its service-plaza operator says unattended overnight parking is prohibited, but a traveler who remains inside the vehicle to rest during the night is allowed.

To keep a safety stop from resembling a campsite, remain in a designated parking space and keep awnings, chairs, grills, tents, outdoor bedding, and other equipment packed away. Slides, generators, and leveling equipment may also attract attention at locations that prohibit camping.

Some states give commercial drivers more time to meet federal rest requirements. Those commercial limits do not automatically apply to a privately used motorhome or tow vehicle.

Rest Area Sleeping Rules in All 50 States

Alabama

Check posted rules: Alabama publishes rest-area and welcome-center locations but no statewide visitor time limit. An ALDOT spokesperson told Land Line that motorists may stop for a couple of hours, and some facilities post no-overnight signs. Do not plan on a full night without confirming the rule at that location.

Alaska

Check posted rules: Alaska regulation 17 AAC 05.045 states that a person may not park or camp longer than the limit posted at a highway rest stop or pullout. The state sets no single limit for every location.

Arizona

Full-night rest supported: Arizona DOT tells motorists to rest sufficiently before returning to the highway and lists no statewide maximum stay on its current rest-area rules page. Both camping and campfires are prohibited.

Arkansas

No clear statewide rule found: ARDOT operates rest areas and tourist information centers, but its public information does not clearly permit or prohibit overnight vehicle sleep. Review the entrance sign or ask facility staff before planning a long stop.

California

Full-night rest supported: California regulations allow vehicles and travelers to remain for up to eight hours in any 24-hour period. The same rule prohibits camping, tents, other shelters, and campfires.

Colorado

Short rest only: A statewide numerical limit was not located, but a CDOT spokesperson has said overnight parking is not allowed. Use Colorado rest areas for fatigue breaks rather than planned overnight stays.

Connecticut

Full-night rest supported at service plazas: The Connecticut service-plaza FAQ allows a patron to remain inside a vehicle and rest during the night. Leaving the vehicle unattended overnight is prohibited and may lead to towing. Other state rest areas are separate facilities, so their signs still need to be checked.

Delaware

Rules vary by facility: DelDOT provides information for the I-95 Welcome Center and Smyrna Rest Area, but it does not publish one statewide rule answering the overnight question. Follow the limit posted at the entrance.

Florida

Short rest only: Florida DOT allows ordinary visitors to stay for up to three hours and prohibits overnight camping. A separate administrative rule gives qualifying commercial vehicles up to ten hours.

Georgia

Full-night rest supported as temporary traveler use: Georgia Code § 32-6-6 allows the normal and temporary use of designated areas for resting or sleeping by people traveling in vehicles. Georgia also prohibits camping and defines it through actions such as erecting a shelter, laying out bedding, cooking, or making a fire.

Hawaii

No general overnight permission: Hawaii law generally prohibits using a vehicle as a sleeping place on highways and other public property from 6 p.m. to 6 a.m. An emergency affecting the operator’s safety is an exception, and designated legal parks or campgrounds are excluded. Hawaii does not have the mainland-style interstate rest-area network addressed in most of this guide.

Idaho

Full-night rest supported: The Idaho Transportation Department allows travelers to rest for up to ten consecutive hours at interstate rest areas and 16 hours at rest areas on U.S. and state highways. Camping, generators, and utility hookups are prohibited.

Illinois

Short rest only: Illinois Administrative Code Part 533 limits a rest-area visit to three hours. Separate provisions prohibit camping, tents, and sleeping overnight on the grounds, benches, or inside buildings. A short sleep inside a legally parked vehicle is not separately banned by that language.

Indiana

Rules vary by facility: INDOT publishes the restriction on individual location pages. Many facilities, including the Lizton Rest Area, are marked “Overnight Parking: No.” Check the selected location through the INDOT rest-area directory before relying on it.

Iowa

Full-night rest supported, subject to posted limits: Iowa rest-area signs have been reported to prohibit parking beyond 24 hours, with exceptions tied to poor weather, reasonable justification, or the need for rest. The Iowa DOT rest-area page does not reproduce that wording, so travelers should confirm the sign on arrival. Overnight camping is prohibited.

Kansas

Full-night stay supported: Kansas Administrative Regulation 36-32-2 expressly permits camping for one night at a rest area. Parking for more than 24 hours is prohibited.

Kentucky

Short rest only: Kentucky regulation 603 KAR 5:040 sets a four-hour limit within a 24-hour period and prohibits camping. That provides time for a nap, but not a planned full night’s sleep.

Louisiana

No clear statewide rule found: Louisiana DOTD lists state rest areas and notes nighttime security at many locations, but its public guidance does not answer the overnight vehicle-sleep question or set a statewide visitor limit. Follow posted instructions and ask security when present.

Maine

Rules depend on the road system: Maine Turnpike service plazas use a four-hour limit for passenger vehicles and a 12-hour limit for commercial vehicles under the Turnpike Authority’s policies and rules. MTA also prohibits camping. No separate statewide rule for MaineDOT rest areas was located.

Maryland

Overnight parking prohibited: COMAR 11.04.07.11 bars overnight parking and camping at state highway rest areas. Another rule limits ordinary use to three hours without a permit.

Massachusetts

Check posted rules: Under 700 CMR 9.03, signs at the facility control use. That provision limits an unattended vehicle at a safety rest area to 30 minutes but does not state the same limit for an occupied vehicle used for sleep. No clear statewide maximum for an occupied vehicle was located.

Michigan

No clear current rule found: Michigan’s rest-area page does not publish an overnight limit. MDOT has posted proposed roadside-facility rules that would allow overnight parking within a 48-hour limit while prohibiting camping, but the agency still labels those rules as proposed.

Minnesota

Short rest only for ordinary motorists: Minnesota DOT policy allows most motorists to stay up to four hours where posted. Commercial drivers may remain for up to ten hours.

Mississippi

Full-night rest supported up to eight hours: MDOT’s rest-area guidance prohibits camping. A 2021 state transportation-agency survey reported an eight-hour limit in Mississippi, giving travelers a practical limit for an occupied rest stop.

Missouri

No clear statewide rule found: MoDOT’s public travel information does not provide a statewide duration or a direct rule for sleeping inside a vehicle. Obey the limit displayed at the facility.

Montana

Full-night rest supported: Montana DOT expressly allows overnight parking with a 12-hour maximum. Vehicles must use one parking space, and camping is prohibited.

Nebraska

Full-night rest supported: Nebraska’s rest-area guide sets a ten-hour maximum and prohibits camping. Ten hours leaves enough time for a normal overnight sleep inside the vehicle.

Nevada

Full-night rest supported: Nevada Administrative Code 408.595 limits parking, camping, or occupancy at a roadside park or safety rest area to 18 hours in any two-week period. The total is cumulative rather than a fresh 18-hour allowance at each stop.

New Hampshire

Full-night vehicle rest supported: New Hampshire RSA 236:58 prohibits tents, camping devices, and sleeping on the ground at highway rest areas. That statute does not prohibit sleeping inside a legally parked vehicle, and no statewide vehicle-parking limit was located.

New Jersey

Short rest only for ordinary vehicles: N.J.A.C. 19:9-1.6 imposes a two-hour general limit on New Jersey Turnpike Authority property. Trucks in designated spaces may stay for ten hours, while buses may remain for eight hours.

New Mexico

Full-night rest supported: New Mexico Statutes § 67-8-22 allows a vehicle to remain for up to 24 hours in any three-day period. One long visit uses the allowance for the rest of that three-day window.

New York

Short rest only for ordinary vehicles: 17 NYCRR 156.3 prohibits parking longer than three hours during darkness at rest areas, parking areas, and scenic overlooks. Qualifying commercial drivers may stay for ten hours. Tents, shelters, and other camping activity are prohibited.

North Carolina

Check posted rules: North Carolina’s statewide rule prohibits tents and other structures used for camping, but it does not clearly address sleeping inside a vehicle or set a statewide duration. Individual facilities may post stricter limits.

North Dakota

No clear statewide rule found: NDDOT maintains rest areas shown through its travel maps, but no public statewide rule was located that directly addresses overnight vehicle sleep or sets a visitor limit. Rely on posted instructions at the site.

Ohio

Full-night vehicle rest appears permitted if the vehicle remains occupied: Ohio Administrative Code 5501:2-4-01 prohibits camping and allows an unattended vehicle to be towed after three hours. No maximum stay is stated for an occupied, legally parked vehicle. Ohio Turnpike service plazas operate under a separate system.

Oklahoma

No clear statewide rule found: ODOT maintains non-turnpike rest areas, while the Oklahoma Turnpike Authority operates separate concession plazas. Oklahoma’s rest-area contact information does not provide an overnight policy or statewide time limit. Identify the operating agency and follow the sign at the stop.

Oregon

Full-night rest supported: Oregon permits motorists to remain at a rest area for up to 12 hours in a 24-hour period. Outdoor camping, tents, and other sleeping accommodations are prohibited.

Pennsylvania

Short rest only at PennDOT rest areas: 67 Pa. Code Chapter 443 allows sleeping in a legally parked vehicle but limits the stay to two hours in a 24-hour period unless another limit is posted. Parking from dusk to dawn is also prohibited at non-interstate roadside rest areas unless posted otherwise. Pennsylvania Turnpike service plazas follow separate rules.

Rhode Island

No clear statewide rule found: RIDOT does not publish a statewide rule directly addressing overnight vehicle sleep at its limited highway rest facilities. Travelers planning more than a brief stop should check posted restrictions or contact RIDOT.

South Carolina

Check posted rules: A 2021 transportation-agency survey reported a two-hour limit for passenger vehicles, but no current statewide SCDOT rule was located to verify that as a blanket policy. Current facility signs provide the best guidance. South Carolina Code § 57-3-640 should not be cited for this question because it concerns roads in state parks, not highway rest areas.

South Dakota

Short rest only for ordinary vehicles: South Dakota Codified Law 31-7-17 defines temporary rest as no more than three consecutive hours for an ordinary vehicle. Commercial motor vehicles may remain for up to ten hours.

Tennessee

Overnight parking prohibited: Tennessee DOT states that overnight parking is not allowed and limits parking to two hours at welcome centers and rest areas. Tennessee law also restricts camping on public property not designated for that use.

Texas

Full-night rest supported: Texas Transportation Code § 545.411 allows travelers to stay at a safety rest area for up to 24 hours. That is one of the longest clearly published allowances in the country.

Utah

Full-night vehicle rest supported, but camping is not: Utah DOT states that overnight camping is prohibited while extended stays are permitted and monitored. Remain inside the vehicle and avoid setting up outdoor equipment.

Vermont

The rule is unclear for sleep inside a vehicle: 19 V.S.A. § 1106 prohibits remaining at a state highway facility for overnight camping unless that facility is designated for it. The law does not clearly state that every instance of sleeping inside a vehicle counts as camping. No statewide vehicle-parking limit was located.

Virginia

Overnight parking prohibited: The Virginia DOT rest-area FAQ directly states that overnight parking is not allowed. Unattended vehicles may be towed at the owner’s expense.

Washington

Full-night rest supported: RCW 47.38.020 permits a person to remain at a rest area for up to eight hours in a 24-hour period. State law also prohibits camping and setting up a tent or other sleeping accommodation.

West Virginia

No clear statewide rule found: West Virginia has standard highway rest areas and separate Turnpike travel plazas, but the state transportation department does not publish one statewide rule answering the overnight vehicle-sleep question. Check the facility sign and its operating agency.

Wisconsin

Full-night rest supported: Wisconsin DOT treats parking beyond 24 hours, or beyond a shorter posted limit, as long-term parking. An occupied overnight stop can fit within that period, but camping is prohibited.

Wyoming

Temporary rest only: Wyoming DOT describes its facilities as places for temporary rest and prohibits overnight camping. WYDOT does not publish a clear statewide time limit for an occupied vehicle, so its guidance does not firmly support a planned full-night stay.

Five Rules for Sleeping at a Highway Rest Area

1. Read every entrance and parking sign: A posted limit can be shorter than the general state rule, and temporary restrictions may apply.
2. Stay inside the vehicle: Many states that allow vehicle rest prohibit sleeping on the ground, on a picnic table, or inside a tent.
3. Keep the RV ready to leave: Avoid awnings, outdoor furniture, grills, campfires, and equipment that occupies another parking space.
4. Use the passenger-vehicle limit: A longer commercial-driver allowance generally does not cover a privately used RV.
5. Move on after resting: Rest areas are intended for highway safety, not multi-day stays or use as a base for nearby activities.

The safest planning rule is simple: check the state’s current guidance before the trip, then follow the sign at the facility. When the published rule is unclear, treat the stop as a short fatigue break rather than assuming an overnight stay is allowed.
