A Mutant Vehicle is a unique, motorized creation that shows little or no resemblance to their original form, or to any standard street vehicle. Mutant Vehicles are radically, stunningly, (usually) permanently, and safely modified from their base vehicle. Sometimes the whole vehicle is made from scratch.

Mutant Vehicles may include such non-standard motorized forms such as furniture, other non-street vehicles such as a boat or train, animals, or just about anything imaginable. For safety reasons, they must not mimic any type of emergency service or law enforcement vehicle.

Vehicles merely stripped to the frame and engine, and vehicles with minimal changes or temporary decorations are not considered Mutant Vehicles. See http://burningman.org/event/art-performance/mutant-vehicles/
