A proactive, prophylactic vehicle fluid capture system that embodies an inflatable air-diaper disposed under the engine. The inflatable air-diaper is deployed upon an indication of a sufficient crash event, wherein the deployed inflatable air-diaper catches the above-mentioned vehicular fluid prior to contact with the surrounding ground, thereby lessening the negative environmental impact and clean-up time resulting from the crash event. The inflatable air-diaper may deploy with peripheral sidewalls to facilitate the retention of the hazardous fluid on the inflatable air-diaper. The inflatable air-diaper is made of material adapted to absorb these hazardous vehicular fluids.
