I can't count how many times I've left work at the end of the day, driven four or five hours toward the mountains or a campsite, and then had to find somewhere to pull over and sleep in my car so I could reach the trailhead early the next morning. It happens over and over, and finding a place to sleep is always the hard part. This guide is what I wish I'd known when I started doing it.

I take road trips on my motorcycle and in my car, and on any drive that runs longer than a day, one question comes up every evening: where am I sleeping tonight? This guide is for beginners driving from point A to point B over several days who want to sleep in the car or pitch a tent along the way. It covers the common places to stop, from the most reliably legal to the "ask first" options, plus the safety and Leave No Trace basics that matter wherever you land. Rules change and vary a lot by place, so treat this as a starting map and check the official page for wherever you plan to stop. Prices were checked in October 2026.

It's a popular time to try this. The Dyrt's 2026 camping report says 82.4 million Americans camped in 2025, including 2.6 million first-timers, and more than half had trouble booking because campgrounds were full. That's a good reason to know your first-come and dispersed options.

⚠ Carbon monoxide: read this first

Never sleep with the engine running in an enclosed space, and don't idle the engine for heat while you sleep. The CDC warns that even a small exhaust leak can build up CO inside a car, so have your exhaust system checked every year.
Never use fuel-burning portable heaters or lanterns while sleeping in a tent, camper or vehicle. That's the U.S. Consumer Product Safety Commission's guidance, and it says this is especially important at high altitude. CDC adds: never use a portable gas camp stove indoors.
CO poisoning symptoms can look like the flu. If you feel off, get to fresh air. CDC also notes that people who are asleep can die from CO poisoning before they have symptoms.
Pack a battery-powered CO alarm and keep it where it would wake you. Michigan's health department advises campers to "always bring a battery-operated CO detector" and to test it before the trip, and CDC recommends battery CO detectors near sleeping areas.

Plan for cold nights with insulation instead: a sleeping bag rated for the expected low and a sleeping pad under you.

1. Public land: BLM dispersed camping

Dispersed camping means camping outside a developed campground, usually free and with no facilities. According to the Bureau of Land Management's national camping page, it's allowed on most BLM land unless an area is posted closed. The usual limit is 14 days in any 28-day period, after which you move roughly 25 to 30 miles away. Rules vary by state and field office, so check with the local BLM field office for the area you're heading to.

Quick link: BLM: Camping on Public Lands lays out the national rules (14 days in any 28-day period, then move 25 to 30 miles). There's no single official BLM page that covers every state's dispersed camping rules, so use it as your starting point and confirm with the local field office.

BLM Idaho says to camp at least 200 ft from water, use already-used sites, and keep vehicle travel to reach a campsite within about 100 ft of roads. Its stay limit is 14 days, then move at least 25 miles.
BLM Utah describes dispersed camping as free with no permit, a 14-day limit, and driving on designated routes only.

The national page also recommends camping within 150 feet of designated routes and at least 200 feet from lakes, rivers and streams.

For an overnight stop on a road trip, that's usually all you need: pull onto an already-used site, sleep, and move on in the morning.

2. Public land: National Forest dispersed camping

National forests generally welcome dispersed camping away from developed sites, but the distances and stay limits are set forest by forest. The U.S. Forest Service says the stay limit is usually 14 days, but some National Forest areas set shorter limits, and some forests allow longer. Here are three examples, checked on the forests' own pages, Oct 2026:

Forest	Stay limit	Distance from road	Distance from water
Fishlake NF	16 days, then move at least 5 road miles	Within 150 ft	200 ft
Olympic NF	21 consecutive days, then leave the forest	Within 150 ft	200 ft
San Juan NF	16 days, then move at least 5 road miles	Within 150 ft	100 ft

Stay limit: usually 14 days, but some areas set shorter limits; check the specific forest (USFS Pacific Southwest Region). Fishlake and San Juan allow 16 days and Olympic allows 21, so limits differ in both directions; elsewhere it's usually 14.

The takeaway: "14 days, 200 ft" is a common rule, not a universal one. Look up the specific forest's dispersed camping page and its MVUM (Motor Vehicle Use Map), which shows which roads you're allowed to drive.

3. Rest areas: a nap, not a campsite

Interstate rest areas are run by the states, so rules vary by state, and I didn't find a single federal overnight rule. Some states allow an overnight stop for a set number of hours, and others prohibit overnight parking entirely. Check the official state DOT page for each state on your route, and follow the posted signs, which control. There's no official site that gathers every state's rest-area rules, but the Federal Highway Administration's State Transportation Web Sites list links to each state's DOT homepage. It doesn't link to rest-area pages, so from there you'll need to find the rest-area info on your state's DOT site, and then follow the posted signs.

4. Bookable campgrounds

If you'd rather have a reserved spot, state parks and county or city parks are often the cheapest bookable option. Booking systems vary by state, and many city parks close at night, so don't assume you can stay in one without a campsite. Federal campgrounds can be booked on Recreation.gov, which is free to browse; its rules page lists an $8 online or $9 phone reservation fee on top of the site fee ($3 in person).

Don't assume a state park parking lot is a free overnight spot. Many parks only allow sleeping in designated campsites. For example, California's Julia Pfeiffer Burns State Park says camping or sleeping inside a vehicle in the parking lot is not allowed, and at California's New Brighton State Beach, vehicles must be parked in a designated campsite or an overflow lot, with a 7-night maximum stay.

5. Businesses that may allow overnight parking

These are "ask first" options. None of them is a guarantee:

Walmart: Walmart's own FAQ says it permits RV parking on store lots "as we are able," with permission up to each store manager and subject to local laws. The policy is written for RVs, so car sleepers should ask too. Call ahead and ask the manager before you settle in.
Cracker Barrel: reportedly decided location by location, so ask the manager.
Cabela's and Bass Pro: reportedly no public corporate policy; it's store by store.
Truck stops: Pilot/Flying J advertises overnight spaces for RVs, but a company spokesperson has said passenger-car parking is meant for short-term rest. Some other truck stops allow short rest stops too; check posted signs, ask inside, and never use the spaces meant for trucks.
Casinos: ask first. Some allow overnight RV parking under their own rules. Casino Arizona, for example, charges $25 a night with a 6-day limit, while others ban sleeping in vehicles. Check the casino's site or call ahead and ask security or the manager.

A note on Harvest Hosts: you'll see it recommended for road trips, but it requires a self-contained RV with a built-in toilet and kitchen. Tents, rooftop tents and cars without a bathroom don't qualify, so it isn't an option for car or tent campers.

Local laws still apply. Rules about sleeping in your car change from town to town, and honestly, the best move is to stop by the local sheriff's office or police department and just ask. There's nothing to be afraid of. They're there to help, they might even point you to a good place to eat, and you'll sleep better knowing you asked.

7. Etiquette and the "knock"

When you're sleeping somewhere other than a campsite, the general best practice is to arrive late, leave early, skip setting up chairs or grills in a parking lot, buy something if you're at a business, and leave no trash. If someone knocks, be polite, explain that you're resting during your trip, and move on if you're asked to. Posted rules and local ordinances always win.

8. Weather, water and bathrooms

Weather and fire: check the forecast before you stop. Most of us sleeping in the car overnight aren't building a fire or grilling anyway. If you do cook, check the fire restrictions first and use a camp stove. A lot of over-the-road work crews do it this way, setting up on BLM land or at an established spot with a grill before they move on to the next job.
Water: assume a dispersed site has no water. Top off at gas stations, rest areas, campgrounds and visitor centers as you go. Carry at least 1 gallon per person per day as a bare minimum (that's Ready.gov's baseline), and more in very hot weather, when your needs can double.
Bathrooms: rest areas and 24-hour stores are the easy options. If you're on BLM land where camping is allowed, follow Leave No Trace: walk about 70 to 80 adult paces (roughly 200 feet) away from water, camp and trails, dig a cathole 6 to 8 inches deep, do your business, and cover it back up. Toilet paper can be buried deep in the hole or packed out in a bag; in the desert, packing it out is best. Wipes always get packed out.

What to bring

Window covers or reflective shades
A sleeping pad or sleeping platform (see my sleeping pad guide)
A sleeping bag rated for the expected low
Plenty of water, plus a way to boil or filter more
A headlamp with a red light
A battery CO alarm
Optionally, a portable power station

If you buy a portable power station, check CPSC recalls first. Several models have been recalled or flagged for fire or shock risk, so search the model on cpsc.gov before you buy or use one.

Leave No Trace, every night

Whether you're in a forest pullout or a parking lot, the seven Leave No Trace principles apply:

Plan Ahead and Prepare
Travel and Camp on Durable Surfaces
Dispose of Waste Properly
Leave What You Find
Minimize Campfire Impacts
Respect Wildlife
Be Considerate of Others

On a road trip, that mostly means using sites that are already worn in, staying the posted distance from water, packing out every bit of trash, and leaving each stop so the next traveler is welcome there too.
