Notes: “Persons Injured” includes all nonfatally injured persons in injury
and fatal crashes. A combination truck is defined as a truck tractor pulling
any number of trailers (including none) or a straight truck pulling at
least one trailer. The Federal Highway Administration (FHWA) implemented an enhanced methodology
for estimating registered vehicles and vehicle miles traveled by vehicle type
for the years 2007-2009. As a result, involvement rates may differ, and in some
cases significantly, from previously published rates.
