FMCSA’s crash database separately tracks cement trucks as a distinct cargo-body type (concrete mixer). For calendar year 2024, FMCSA recorded 22 cement trucks involved in reportable crashes in Washington and 1,486 nationwide. These figures cover large trucks and do not represent every minor collision.
Under FMCSA’s reporting standard, a reportable crash involves a fatality, an injury requiring immediate medical treatment away from the scene, or damage severe enough that a vehicle must be towed from the scene.
But statistics alone can’t convey what a serious crash may mean for an injured person or grieving family. They do, however, reinforce why commercial truck safety matters and why a serious cement truck collision deserves careful investigation.
Why Do Cement Trucks Present Unique Safety Risks?
Washington regulations describe ready-mix operations as involving trucks that carry premixed concrete or raw ingredients such as cement, sand, gravel, stone, and water, with the material potentially being mixed in a revolving drum while the truck travels to a project site. The design helps cement trucks perform an essential job, but it also creates operating characteristics that drivers and companies need to respect.
Cement Trucks Can Have Stability and Rollover Problems
Cement trucks may be particularly vulnerable to stability problems because of their body design and load.
U.S. Department of Transportation research has specifically identified rear-discharge cement trucks as vehicles that may present stability issues because of the rotating drum mounted on the truck. The same research notes that body types and loads can significantly affect a commercial vehicle’s mass, center of gravity, and overall vehicle dynamics.
Rollovers can endanger not only the cement truck driver but everyone nearby. A truck that tips into an adjacent lane can crush a passenger vehicle, strike a pedestrian or cyclist, or create a multivehicle collision.
Cement Trucks Can Be Exceptionally Heavy
Weight changes the way a truck accelerates, turns, stops, and responds during an emergency.
Washington law contains detailed axle and tire weight requirements for heavy vehicles and specifically recognizes ready-mix concrete trucks in its axle-loading provisions. RCW 46.44.042, for example, contains a provision addressing rear booster trailing axles on ready-mix trucks.
The technical requirements will not be relevant to every accident. But when weight, axle configuration, stability, braking, or vehicle condition may have contributed to a crash, those issues deserve investigation.
Cement Trucks Frequently Operate Around Construction Sites
Cement trucks do not simply travel from one highway terminal to another. Their work often takes them directly into construction areas. That may require a driver to turn across traffic, enter or exit temporary access points, back into confined spaces, travel on temporary roads, maneuver around workers or pedestrians, and operate on uneven or unfinished surfaces.
When a crash occurs near a construction site, an investigation may need to examine both the driver’s conduct and the safety of the site itself.
