Can you sleep at rest stops? The rules in every state

Updated October 2026

In most states you can take a nap in your car at a highway rest area, but how long you may stay differs a lot. Some states set a limit of two or three hours, others allow a full night, and a few ban overnight parking outright. Camping, meaning tents, grills or setting up outside the vehicle, is not allowed at rest areas in any state we checked.

The table below lists the rule we found for each state, with the law or official page it comes from. Where we found no statewide rule, the posted signs at each rest area apply. Signs can always be stricter than the state rule.

What the limits mean in practice

A time limit usually applies per visit or per 24 hours. Highway patrol officers in many states will wake a sleeping driver to check on them, not to fine them, especially if the driver is clearly resting for safety. Truck drivers often get longer limits because federal hours-of-service rules force them to stop.

If you need a full night of sleep and the state limit is short, look for a truck stop, a campground or a hotel instead. Some big-box stores allow overnight parking, but that is a store decision, not a right.
