In 2003 there were 6328000 car accidents in US.
33,808 people were killed in traffic accidents. 10,839 of these deaths was a result of alcohol (32% of all traffic deaths)
I have no data on total deaths in 2006, but there were 43,200 deaths in traffic crashes in 2005.
On average, there are around 40,000 deaths from road traffic accidents in the US each year. This translates to about 100 deaths per day.

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.
