Though Trucks play an important role in American economy, if they do not follow the laws when on road they can be deadly. Transport and delivery companies run large commercial trucks like tractor-trailers weighing more than 20 times a regular passenger car. If these trailers meet with an accident, the smaller vehicles would be completely crushed under their weight and result in a horrifying accident. Victims of truck accidents whether those riding the truck or those hit by the truck will either be dead or sustain severe brain or spinal injuries. Injuries from a trucking accident are always of a very serious nature.
