Can't find anything on Snopes about the hybrid cars + hazardous waste stuff. The batteries used are the typical lead-acid unit, similar to the batter that's already in your car. The worst that would happen is spillage of sulfuric acid, and while that's not the best stuff to be rolling around in nekkid, cleanup is pretty straight forward.
Perhaps the better question: are there enough batteries, and in those batteries enough sulfuric acid, to constitute a hazmat situation IF the entirety of the acid was leaked? I don't know what the threshold is between something you and I can clean up versus what the hazmat team has to come out and do for you...
Might also be more dependant on location of the accident (near some factory, or water treatment plant, or ???) as to whether it necessitates a hazmat response.
