Houston Truck Accidents Many large truck accidents are caused by defective parts and / or equipment that has not been maintained or replaced when necessary. The most common equipment causes of terrible truck crashes are brake failure and tire failure. Other equipment causes include failures with trailer hitchs, taillights, loading straps, and hydraulic systems. In almost all cases, the primary cause can be traced to human failure - failure to inspect, failure to maintain, failure to replace, failure to follow regulations.
