The Legality of Car Sleeping in Wyoming: What You Need to Know

Driving across the wide-open highways of Wyoming can be long and tiring. With miles of road between towns and services, it’s not uncommon for drivers to feel drowsy and in need of a break. The good news? Yes, you can sleep in your car in Wyoming — but there are some important rules and safety tips you should know before pulling over for a nap.

Is It Legal to Sleep in Your Car in Wyoming?

Short answer: Yes.
Long answer: It’s legal to sleep in your car in Wyoming as long as you’re doing so in a safe and legal location.

Wyoming law doesn’t specifically ban sleeping in your vehicle. In fact, the Wyoming Department of Transportation (WYDOT) even supports it for safety reasons. If you’re too tired to drive, stopping to rest — even for a full night’s sleep — is encouraged. However, you should be mindful of where you park.

Where You Can Sleep in Your Car

Rest Areas

Wyoming has 37 rest areas across the state. These are ideal spots for a break. WYDOT allows drivers to take more than just a quick nap — you can get a full night’s rest here. Just don’t turn it into a camping trip or stay for an extended time.

City Streets

Sleeping in your car on public city streets is also allowed as long as it’s a legal parking zone. Avoid “No Parking” areas or time-restricted spots. As long as you’re not breaking local parking laws, you’re usually good to go.

Parking Lots (With Permission)

Some truck stops, big-box stores, or public parking areas may allow overnight parking. Always check for signs or ask permission if you’re unsure. Parking on private property without permission could lead to a trespassing charge or your car being towed.

When Sleeping in Your Car Becomes a Problem

If You’re Drunk

This is where it gets tricky. If you’re under the influence and choose to sleep it off in your car, you could still be charged with a DUI — even if you’re not driving. Law enforcement may consider your vehicle as a potential threat if you have access to the keys or if you’re in the driver’s seat.

Tips to Avoid a DUI While Sleeping in Your Car:

• Do not sleep in the driver’s seat
• Keep the keys out of reach
• Clearly show that you’re resting, not pausing to drive
• Sleep in the back seat or reclined passenger seat

While these steps won’t guarantee you avoid a charge, they may help your case if it comes down to it.

Safety Tips for Sleeping in Your Car

Sleeping in your car can be a smart and safe choice, but here are some important precautions:

• Tell someone where you are, especially if you’re in a remote area.
• Avoid roadside parking; instead choose well-lit rest areas or truck stops.
• Don’t leave your engine running — it’s a fire and gas hazard.
• Keep your windows mostly closed for security but crack one slightly for airflow.
• Lock your doors before you fall asleep.
• Cover windows with blankets or coats for privacy.
• Pack a blanket in your car, especially during colder months.

Whether you’re road-tripping, driving cross-country, or simply too tired to keep your eyes open, sleeping in your car in Wyoming is legal and often encouraged — if done safely and responsibly. Always stay alert to where you’re parking, avoid being under the influence, and prioritize your safety. Taking a proper rest could save your life and the lives of others on the road.
