Some of our most-read guides on unusual driving laws and DUI edge cases.
Is it illegal to sleep in your car?
Usually no, not as a blanket statewide crime. But where you park, how long you stay, whether local ordinances ban vehicle sleeping, and whether alcohol is involved all matter more than the nap itself.
Is it illegal to drive with interior lights on?
Usually no. There is generally no standalone law saying your dome light turns your car into a crime scene. But if the light causes distraction, glare, or reduced visibility, an officer can still use broader unsafe-driving rules.
Can you get a DUI on a bicycle?
Sometimes. Drunk cycling is not handled the same way as drunk driving everywhere, but many jurisdictions still allow citations or charges when an intoxicated rider creates a danger.
Can you get a DUI on a snowmobile?
Yes, often. In many states snowmobiles have their own impaired-operation rules or are treated as vehicles for OUI/DWI purposes.
Can you get a DUI on a horse?
Often yes. In many jurisdictions, impaired riding on a horse can lead to a DUI-style charge or a closely related public-safety offense, but the exact legal theory varies from place to place.
Can you get a DUI on a ATV?
Often yes. Many states treat ATV riding under the influence as a real offense, either under general DUI law or vehicle-specific impaired-operation rules.
