There is a very good reason why there are extra requirements for commercial driver's licenses in the case of truckers who carry hazardous materials: they can cause much greater damage or injury than a normal trucking accident, and the driver must be able to warn people about and stabilize a hazardous materials accident scene. As many as 70% of all tanker trucks are carrying hazardous materials at any given time, increasing the opportunity for a tanker truck crash and dangerous fire. In addition, if any of those tankers have improper load limits, when the truck shifts, the cargo shifts, and that "slosh factor" may cause a tanker truck crash. In those tanker truck crashes, the potential for injuries and fatalities climbs because innocent bystanders can be included. If you have been injured in a tanker truck crash, you should consult a truck accident lawyer to protect your rights.
