The car that you drive may have a greater outcome on the car accident than you may think. Each car has something different put into the vehicle build. Certain cars may be safer than others, but that's not always the case. Car safety is a big factor in purchasing a car.

Some of the cars that you purchase may not be as safe as you think they will be. Some people think that the heavier the car, the more damaged will be done. According to law two, the heavier the striking object, the more gradually it slows down. Less deceleration means a lower likelihood of occupant injury, but there can be mitigating factors that can un-do the benefits of greater weight. The effectiveness of crumple zones and safety systems can be more critical than vehicle weight.

Another factor that could make the collision worse is the speed. This is where velocity is a critically important factor. The kinetic energy of the vehicle and its contents rises with the square of its speed. In other words, the energy of a car traveling 60 mph is four times higher than the energy of the same vehicle traveling 30 mph.

There are several ways in a car to be safer. Passenger restraints such as seat belts — often in conjunction with laws requiring their use — and airbags are required in all vehicles, and they are used to prevent less severe, if any, injuries.
