Sleep in Car Safely: How to Stay Comfortable and Legal While Resting in Your Vehicle

When you need to rest in your car—whether you’re on a road trip, waiting for a shift, or between homes—sleep in car safely, the practice of resting in a vehicle without compromising health, safety, or legality. Also known as car sleeping, it’s a practical solution for many, but it’s not as simple as just turning off the engine and closing your eyes.

Park in the shade, use sunshades, and never leave bottled water or electronics in direct sunlight—they can overheat or explode. And don’t forget hydration. Even if you’re not active, your body loses moisture while you sleep. Keep water nearby, but avoid alcohol or heavy meals before resting.
