33,963 is the number of US Traffic Deaths in 2009

Source: DOT

The number of U.S. traffic fatalities reported at the end of 2009,
which was the lowest level since 1954. According to the U.S.
Department of Transportation, the number is 8.9 percent below the
37,261 deaths reported in 2008 and translates to a fatality of 1.16 fatalities
per 100 million miles traveled.

This should lower loss ratios and lead to further softening in the insurance marketplace. It would be interesting to see if trucking insurance carriers could carve out the fatalities they have had per 100 million miles traveled.
