Yes, you can legally sleep in your car in Wisconsin, but there are important rules and exceptions to understand. The state allows car sleeping at rest areas and waysides for up to 24 hours, as there is no specific law prohibiting it. However, you must be parked legally-illegal parking is not permitted whether you are asleep or awake.
Where and When Is It Allowed?
- Rest Areas & Waysides: Overnight parking and sleeping are allowed for up to 24 hours. These areas are open 24/7, so you can arrive in the evening and leave the next morning without issue, as long as you are there only to rest.
- Private Property & Businesses: Always get permission before sleeping in parking lots of businesses like Walmart or truck stops. Local ordinances may vary, so check signage and local rules.
- City Streets & Residential Areas: Laws and enforcement can differ by municipality. Some towns may have ordinances against overnight parking or sleeping in vehicles, so always check local regulations and posted signs.
Key Restrictions and Risks
- No Camping: Wisconsin law prohibits camping along highways or adjacent lands, which can include some rest areas. However, sleeping in your car for rest (not camping with equipment) is generally permitted.
- 24-Hour Limit: You cannot stay parked in one spot for more than 24 hours at a rest area or wayside, or you risk being towed.
- OWI (Operating While Intoxicated): If you are intoxicated, you can be charged with OWI even if you are only sleeping in your car and not driving. Factors such as where you are sitting (driver’s seat vs. back seat), whether the keys are accessible, and if the engine is running can all influence whether you are considered “operating” the vehicle under the law. Sitting in the back seat with the keys out of reach is safer if you need to sleep it off.
Practical Tips
- Park only where it is legal and safe.
- Don’t exceed the 24-hour limit at rest areas.
- Avoid sleeping in the driver’s seat, especially if you have consumed alcohol.
- Keep your keys out of the ignition and out of reach if you are impaired.
- Be prepared to show your license, registration, and insurance if approached by law enforcement.
