The Missouri Highway Patrol has stepped up its inspections of hazardous materials trucks in the wake of the September 11th terrorist attacks. Word shortly after the attacks that some people had illegally obtained hazardous hauling licenses alerted highway patrols and state police agencies across the country. In Missouri, word quickly went out to highway patrol inspection officers and troopers to be more diligent in checking the trucks and their drivers. There is one good piece of information about the hazmat trucks: they are usually the best-maintained trucks on the road.
