Traffic crashes by far. Most recent stats I could find showed about 29,500 total firearm deaths in the US (not just handguns, all firearms). Traffic crashes accounted for about 42,500 deaths. If you're talking about accidental deaths (that is, many of the 29,500 firearm deaths are intentional), traffic accidents are much, much more likely to cause a death than an accidental firearm death.
