Key takeaways
- Rest areas are run by the state: restrooms, parking and picnic tables – usually no fuel or food on interstates.
- Truck stops are private businesses at exits: fuel, food, showers, truck parking and repair, open 24 hours.
- Service plazas sit on toll roads and combine both: fuel and food right on the highway.
- Welcome centers are rest areas near state lines with staff and travel information.

Rest areas
Rest areas are built and run by state departments of transportation. We list 2,401 rest areas and welcome centers in the US.
They offer restrooms, parking for cars and trucks, picnic tables and often vending machines and pet areas. On the Interstate System, federal law (23 U.S.C. 111) generally prohibits commercial services such as fuel and food sales at rest areas, with exceptions for older facilities and vending machines. That’s why you won’t find a gas station at a typical interstate rest area.
Rest areas are great for a quick break directly on the highway – no exit, no traffic lights. On divided highways they usually serve one direction. Time limits for staying vary by state; see Can you sleep at rest areas?.
Truck stops
Truck stops (travel centers) are private businesses at highway exits. We list 2,672 of them.
Built around truck drivers, they offer diesel and gas, restaurants, convenience stores, paid showers, laundry, large truck lots, and often truck repair and certified scales. Most are open 24 hours. For cars and RVs they’re a good alternative when you need fuel, food or a well-lit place at night – but the truck lot is for trucks.
See truck stops and truck stops with showers.
Service plazas
Service plazas (service areas, travel plazas) are found mostly on toll roads such as the New Jersey Turnpike or the Pennsylvania Turnpike. They sit inside the toll system and combine the convenience of a rest area – right on the highway – with fuel and food like a truck stop.
Because you can’t leave a toll road without paying, service plazas are often the only places to buy fuel for long stretches. See all service plazas.
Welcome centers
Welcome centers are rest areas near a state line, usually on the side of the highway entering the state. They tend to be larger and better equipped, with staff during the day, maps, brochures and travel information, and restrooms around the clock.
Which one should you pick?
- Quick restroom break: rest area or welcome center – no exit, back on the road in minutes.
- Fuel and food: truck stop at an exit, or a service plaza on a toll road.
- Shower: truck stop (most chains sell showers to anyone).
- Sleeping in a car or RV: rest area within the state’s time limit, or a truck stop that allows it – ask first.
- Truck driver’s 10-hour break: truck stop or truck parking; rest areas only where the rules allow a full break.
- Weighing: truck stop with a certified truck scale.
Rest areas vs. truck stops for truck drivers
For truck drivers, the difference is mostly about parking and time. Rest areas are free and right on the highway, but they have few truck spaces and many states limit how long you may stay. Truck stops have large lots, fuel, food, showers and repair, and they’re where most drivers spend their 10-hour break – but lots near cities fill up early in the evening, and some locations sell reserved spaces.
A common pattern: use rest areas for the 30-minute break during the shift, and a truck stop or dedicated truck parking for the overnight break. See truck rest stops and truck parking.
Rest areas vs. truck stops for RVers
RVers use both. Rest areas are the easier stop for a quick break – long-vehicle spaces, no maneuvering at fuel islands, back on the road in minutes. Truck stops are better for fuel (diesel lanes fit large rigs), propane at some locations, dump stations at some travel centers and a well-lit place for the night if the manager allows it. See RV dump stations.
Costs
Rest areas, welcome centers and their restrooms are free. At truck stops and service plazas, restrooms are free for customers; showers are usually paid (truck drivers often earn free showers with fuel purchases), and reserved truck parking costs extra where it’s offered.

Frequently asked questions
What is the difference between a rest area and a truck stop?
A rest area is run by the state and offers restrooms and parking, usually without fuel or food. A truck stop is a private business at an exit with fuel, food, showers and large truck lots.
Why don’t interstate rest areas sell gas?
Federal law (23 U.S.C. 111) generally prohibits commercial services at rest areas on the Interstate System, with exceptions for older facilities and vending machines.
Is a service plaza a rest area?
Not quite. Service plazas are on toll roads and sell fuel and food; rest areas are run by state DOTs and usually don’t.
Can cars use truck stops?
Yes. Truck stops sell fuel, food and showers to everyone; just park in the car area, not the truck lot.
