Commercial Motor Vehicle Repairs

Commercial Motor Vehicle Repairs

In the United States, there were nearly 600,000 motor carriers—common, contract, or private—using buses or trucks to provide commercial transportation of passengers or freight in 2000 [2]. These companies accounted for 28 percent of the nation’s freight ton-miles and 3 percent of passenger-miles that year1 [1]. Repair data for most of this fleet are not public information.

Over 2.0 million roadside truck inspections were completed in 2001, up from 1.6 million in 1990, to ensure that trucks are in compliance with federal safety regulations and standards (figure 50). Nearly one-quarter of those inspected in 2001 were taken out of service for repairs (figure 51). Although the number of inspected trucks taken out of service for repairs has remained fairly constant, the proportion of those trucks as a percentage of all inspected trucks has declined from 34 percent in 1990 to 23 percent in 2001.

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.

1 Ton-miles are calculated by multiplying the weight in tons of each shipment transported by the miles hauled. Passenger-miles are calculated by multiplying the number of passengers transported by the number of miles traveled.
