- The fine print
- Full-text search of Wyoming Statutes Titles 31 and 24: no prohibition on sleeping, camping, lodging, or living in a vehicle. Local ordinances vary by city.
Parking overnight to sleep and camping are two different acts under most rules. Camping usually means setting up outside the vehicle: a tent, an awning, chairs, a fire. Staying inside a legally parked vehicle is often treated differently. Which one applies to you.
The posted sign and the officer on the ground beat this table. Rules change; the date above is when we last checked.
Wyoming’s statutes contain no prohibition on sleeping, camping, lodging, or living in a vehicle. That is not an assumption: we ran a full-text search of Title 31, the motor vehicle code, and Title 24, the highways code, on 2026-07-17, and the prohibition is simply not there.
What state law says
Nothing, on this subject, and it helps to know the search was thorough rather than casual. Titles 31 and 24 cover registration, rules of the road, parking, and highway administration. None of it addresses a person asleep in a parked vehicle. If your car is legally parked in Wyoming, no state statute cares what you do behind its windows at 2am.
The layer that remains is municipal. Cheyenne, Casper, Jackson, and every other town can write parking ordinances for their own streets, and those vary. Jackson in particular sits in a resort valley where parking pressure is real, so do not carry the state’s silence into town limits without checking. The posted sign on the block outranks this page everywhere.
Rest areas have their own answer, and it is friendlier than most states. WYDOT’s rest area brochure allows sleeping in your vehicle and prohibits camping, with the line drawn at setting up: no tents, no extended RV slideouts, no arranging the site for a stay. No hour cap is stated. The brochure dates to 2011, which is old for a source, so if a posted sign at a rest area says something stricter, believe the sign. Details on the Wyoming rest areas page.
Where people actually get in trouble
In Wyoming, rarely for the sleeping itself. The realistic problems are a posted street in a town with an ordinance, a private lot without the owner’s permission, and winter: a January night in a car at 7,000 feet is a safety problem before it is ever a legal one. Run the numbers on staying warm before you count on a parking spot.
How to check locally
Check the municipal code or call the non-emergency line for the town you are stopping in. Ask the manager before staying in a business lot; truck stops are the reliable yes. And remember what surrounds the towns: over 18 million acres of BLM land and 8 national forests, where a car and a sleeping bag are the intended use rather than a gray area. Free camping in Wyoming covers where and under what stay limits.
