No, it is generally illegal and extremely unsafe to drive a car with no doors on public roads in the United States. The primary reason is that doors are a critical part of the vehicle's safety structure, specifically the B-pillar, which provides essential protection in a side-impact collision. Driving without doors compromises the car's structural integrity, putting you at severe risk of being ejected during a crash. Furthermore, vehicle codes in all 50 states require that a vehicle on public roads be in a safe operating condition, which explicitly includes having all original equipment, like doors, properly attached.
The legality hinges on the specific state's vehicle equipment laws. While some states have more lenient regulations for modified vehicles or off-road use, none permit a standard passenger car to operate without doors on public streets. For example, many states require features like fenders, mirrors, and safety belts to be functional, which is impossible without doors. The table below outlines the door-related requirements in a sampling of states.
| State | Door Requirement / Relevant Vehicle Code |
|---|---|
| California | Vehicle Code § 24011: Prohibits operating a vehicle that is unsafe or not equipped as required. |
| Texas | Transportation Code § 547.001: Requires vehicles to be equipped with original OEM safety equipment. |
| Florida | Statute § 316.271: Mandates that every vehicle be in good working order and safe mechanical condition. |
| New York | VAT § 375: Requires a vehicle to be equipped with all parts in good working order. |
| Arizona | ARS § 28-954: Allows for modification but requires equivalent protection, which doors provide. |
Beyond legality, removing doors creates significant safety hazards. You lose side-impact protection, increasing the risk of injury. You are also more exposed to road debris and the elements. Wind buffeting at speed can make the vehicle difficult to control and cause hearing damage. While images of doorless Jeeps are popular, these are typically intended for off-road use at low speeds. For daily driving, keeping your doors on is a non-negotiable safety measure.

Trust me, you don't want to try it. I live in a state where you see a lot of Jeeps with the doors off in the summer. But even those guys are super careful and only do it on slow backroads. On a highway? It's terrifyingly loud and windy—you can barely hear yourself think. The car feels totally different, like it could get pushed around by a gust of wind. It's just not worth the risk for a thrill. Keep the doors on where it's safe.

From a technical standpoint, the engine will run and the wheels will turn. However, the vehicle's unibody chassis is engineered with the doors as a structural component. Their removal compromises rigidity and safety systems. The risk of partial ejection during a rollover or side-impact is drastically increased, as the seat belt anchorage points are often integrated into the door frame. What seems like a simple modification critically undermines the entire safety design of the vehicle, making it unfit for road use.

As a legal matter, the answer is a definitive no. State vehicle codes universally require that a motor vehicle be maintained in a safe operating condition. Driving without doors is a clear violation of these statutes, as it creates an imminent hazard. You would be subject to citation for an equipment violation, and in the event of an accident, you would be likely found negligent per se, meaning your violation of the law itself would establish your fault, leading to serious liability.
