The National Highway Traffic Safety Administration (NHTSA) said that the number of persons killed in truck crashes declined to 5,212 in 2005, down from 5,235 in 2004.

The fatality rate has not yet been determined because the agency has not calculated the total number of truck miles traveled last year.

However, industry experts expect the rate to drop as well because truck capacity tightened in 2005.
