Vehicle and driver rates
Inspectors put the truck out of service in 28.2% of vehicle inspections of dirt, rock and aggregate haulers (42,011 of 148,942), against 22.6% for all carriers. Drivers went the other way: 4.8% out of service, against 6.2%.
Dump trucks run loaded on rough haul roads and through pits, which is hard on tires, brakes and suspension. Most of their trips are short and local, which keeps hours-of-service and logbook violations low.
FMCSA still shows a national average next to every carrier: 20.72% for vehicles and 5.51% for drivers, figures from 2009 and 2010. The all-carrier rates above come from current inspection records.

Next steps
Compare a hauler's rate with haulers doing the same work, not a national figure from 2009 and 2010. A dump truck hauler at 25% is below the dump truck average of 28.2%, though above the all-carrier rate. A rate built on two or three inspections means little. Check a hauler on HaulStanding for its vehicle and driver out-of-service rates and the inspection count behind each.
How we counted. FMCSA public tables on data.transportation.gov, counted October 13, 2026. "Dump truck haulers" are active for-hire carriers that describe their cargo as dirt, rock, aggregate, asphalt, frac sand or dump work, or whose name says the work. FMCSA does not record truck body type. How we define the groups. Per FMCSA's definitions, vehicle rates use inspection levels 1, 2, 5 and 6; driver rates use 1, 2, 3 and 6. Fleet size is trucks reported. Dry bulk haulers: 25.2% vehicle, 3.8% driver, over 6,769 vehicle inspections.
Public records as FMCSA publishes them, which can contain errors. Figures describe groups, not any one carrier. Not legal advice.
