"Every day there are more than 800,000 shipments of hazardous materials (hazmat) in trucks-usually flammable liquids, such as gasoline, or flammable gas. About 200 hazmat trucks a year are involved in fatal crashes and 5,000 in nonfatal crashes. Although these numbers are small relative to the totals of almost 5,000 trucks involved in fatal crashes and 400,000 involved in nonfatal crashes annually, the potential for human injury and property damage in hazmat crashes is much greater."
