Load securement and licensing
Load securement: 5.3% of dump truck out-of-service violations, against 3.6% for all carriers. Most is one line, cargo not secured against leaking, spilling, blowing or falling: 2,654 violations, an untarped or overloaded bed.
Licensing: operating without a valid CDL appears 4,416 times. Medical certificate and logbook violations are rarer than for other carriers, which fits short local runs.
Next steps
A walk-around catches most of these before the truck leaves the yard: tire pressure, brake adjustment, a tarp. A hauler's inspection history shows whether that walk-around happens. Check a hauler on HaulStanding for its inspections and out-of-service count over the last 24 months.
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. Counts are violations, not inspections; one inspection can carry several. Dry bulk haulers: 2,718 out-of-service violations, also led by tires and brakes.
Public records as FMCSA publishes them, which can contain errors. Figures describe groups, not any one carrier. Not legal advice.
