From the tables of fatalities per 100 million miles that the Federal Motor Carrier Safety Administration compiles [0], the accident rate for trucks went up from 1.03 to 1.29. Passenger vehicle crashes are actually lower, going from 1.03 to 1. These are still on the low end historically: both rates were around 1.36 15 years ago.

Thanks for the tables. They also show that the 2012 rates were somewhat lower than the 2007 rates, and much lower than they ever were before 2007 (>= 1.95).

I still think it's right to expect sustained improvement over the long-term.
