In the United States, there were over 662,000 active motor carriers—common, contract, or private—using buses or trucks to provide commercial transportation of passengers or freight in 2004 . Trucking accounted for 28 percent of the nation’s freight ton-miles in 2001 . Repair data for most trucks are not public information.
Over 2.1 million roadside truck inspections were completed in 2003, up from 1.9 million in 1993, to ensure that trucks are in compliance with federal safety regulations and standards (figure 8-1). Nearly one-quarter of those inspected in 2003 were taken out of service for repairs, 3 percent fewer than in 1993. Trucks are taken out of service when they receive a serious violation during the inspection process.
The downtime for a truck undergoing an inspection can vary from 30 to 60 minutes. Trucks that are placed out-of-service for repairs may be delayed from a few minutes to several days, depending on circumstances.
