Sleeping in your car in Idaho is generally legal, but recent legislation has introduced restrictions in certain areas and under specific circumstances. Here’s what you need to know about the legality of car sleeping in Idaho in 2025.
General Legality
In most parts of Idaho, sleeping in your car is legal, provided you are parked safely and not violating local parking ordinances. This includes resting at designated areas like highway rest stops or private parking lots that permit overnight stays. However, the situation changes significantly in cities with populations exceeding 100,000, such as Boise.
Restrictions in Larger Cities
A new law, Senate Bill 1141, signed by Governor Brad Little in April 2025, bans sleeping in vehicles on public property within cities with over 100,000 residents. This includes streets, parks, and other public spaces. The law explicitly prohibits using a car as a temporary dwelling or lodging space on public property for prolonged periods. Exceptions are made for commercial vehicles and recreational camping in designated areas.
The intent behind this legislation is to address public camping concerns and maintain the cleanliness and safety of urban spaces. However, critics argue that it disproportionately affects homeless individuals and travelers living out of their vehicles.
DUI Concerns
Idaho law also has strict regulations regarding sleeping in a car while intoxicated. Even if you are not actively driving, you can be charged with a DUI if you are found to be in “actual physical control” of the vehicle.
This includes situations where you are seated in the driver’s seat with the engine running or even if the vehicle is parked but operational. Sleeping off intoxication in the backseat may reduce the risk of a DUI charge but does not guarantee immunity from legal consequences if other factors suggest impairment.
Safety Considerations
While legal in most areas outside major cities, sleeping in your car comes with safety risks:
- Weather Hazards: Idaho’s extreme temperatures can pose dangers such as hypothermia during winter or heatstroke during summer.
- Parking Rules: Ensure your vehicle is parked legally and not violating private property restrictions or “no overnight parking” signs.
Exceptions
Senate Bill 1141 allows for overnight camping or parking for recreational purposes at designated locations like Idaho rest areas or private businesses that comply with established rules. Travelers should seek out these spots to avoid penalties.
Penalties for Violations
Violating the new law by sleeping in your car on public property within cities like Boise could result in fines or other penalties. Additionally, DUI charges for intoxicated individuals found sleeping in their vehicles can lead to severe consequences such as license suspension, hefty fines, or jail time.
Recommendations
To avoid legal issues while sleeping in your car:
- Park at designated rest stops or private lots that allow overnight stays.
- Avoid sleeping on public property within larger cities like Boise.
- If intoxicated, ensure your vehicle is turned off and avoid sitting in the driver’s seat.
Sleeping in your car remains legal across much of Idaho but is now prohibited on public property within larger cities due to Senate Bill 1141. Drivers should stay informed about local laws and prioritize safety to avoid fines or legal complications.
