A method of transporting a vehicle that has a ruptured fluid container from an accident includes affixing a fluid absorbent diaper to the vehicle at the location of the ruptured fluid container. The diaper has an absorbent planar member being at least about half the size of the vehicle undercarriage and a plurality of spaced bungee straps extending from edge portions of the member. The vehicle can then be transported and/or stored without risk of spillage of hydrocarbon fluid or battery acid.
