American Trucking Associations’ Technology & Maintenance Council found that there are has been an increase in the frequency of unscheduled roadside maintenance for fleets industry-wide in first quarter 2021, according to data gathered through the TMC/FleetNet America Vertical Benchmarking Program
The TMC/FleetNetAmerica survey found that during the first quarter of 2021, fleets averaged 29,506 miles of operation between unscheduled road repairs – down 18.7% from the fourth quarter of 2020.
Truckload carriers averaged 21,856 miles between breakdowns, a 13.1% decrease in miles from the previous quarter. The time between breakdowns for LTL carriers dropped 18.7% to 44,380 miles in the first quarter from 54,556 in the final quarter of 2021. The tank truck sector saw a slight improvement, running 17,420 miles in the first quarter, down from 19,905 in the previous quarter.
“The data tells us that if, for example, the truckload carriers running the average miles between breakdowns could reach best-in-class performance, they would increase their miles between breakdowns by 89%,” said Emily Hurst, manager of data and analytics at FleetNet America, in a press release.
The data indicates that the maintenance practices of the best-in-class fleets in each vertical resulted in lower costs for those fleets. For example, the leading fleet in the tank vertical operated twice as many miles between roadside breakdowns than the average for the tank vertical.
Understanding the frequency of roadside failures, and how a fleet’s experience compares to similar operations, can help maintenance leaders identify opportunities to improve their operations and reduce their maintenance expense, TMC officials said.
