They also have the highest accident rate of all drivers. Accidents are cause by speeding, driving in the wrong lane, making improper turns, and breaking other rules of safe driving. Cars has become safer over the years because of advances in its design and manufacture. Car manufacturers must meet strict government standards designed to prevent accidents and to protect drivers and passengers. Standards to protect car occupants include the installation of automatic seat belts or airbags, head restraints, and bumper system. Seat belts are probably the main safety equipment. Modern road building techniques have increasingly lowered the risk of car accidents. To build safe roads, engineers consider such factors as road foundations and surfaces, lighting, safety barriers, and grading. Collisions or human errors are occurred in most car accidents. The immediate cause of injury or death in traffic accidents are numerous, such as broken glass, fires, the crushing of the vehicle, hurling the passenger against the car itself. In a collision there is a very large change in velocity in a very short period of time. 59% of injury producing accidents are front end collisions. Therefore there is a major effort in designing front end of automobiles so that they will crumple in a way that results in a uniform acceleration over a relatively long distance, in order to keep the forces on the passenger low. In each car crash there are actually three collisions car collision, human collision, and internal collision. Car collision is during a crash, the car crashes to a stop. At 30 mph, a car hitting an object that is not moving will crumple in about two feet. As the car crushes, it absorbs some of the force of the collision. The second collision is the "human collision". At the moment of impact, ...
