Many truck wrecks result in death or serious injury. A truck weighs at least 10 times more than a regular full size sedan vehicle or even an SUV; just imagine a loaded truck and how much more it would weigh.Think about a load on a truck to be equal to as many as 15 cars hitting your vehicle/car at once. The difference in height of a truck bumper and a vehicle is another added injury factor. The inital layer of protection of your car is the bumper. The difference in height causes the hardest portion of the bigger vehicle to make contact with the softer portion of your car. That is one battle that your car was not designed to win.
A side impact with a truck is generally deadly. If you are driving next to a truck and the side mirror is not visible, the odds are the driver cannot see you. Drive smart and defensive, do not stay in the blind spot of an 18 wheeler for more than a few seconds.
