Most modern cars come with many features designed to reduce the risk of injury to the driver and the passengers in case of an accident. Some of the main types of safety features include:SeatbeltsSide and front air bagsAnti-lock breaking systems (ABS)Traction ControlSeat belts: In the event of a crash, seat belts are designed to keep you inside the vehicle. They also reduce the risk that you will collide with the steering wheel, dashboard, or windshield. New seat belt features such as, adjustable upper belts, seat belt pretensioners and rear-centre shoulder belts. Adjustable upper belts can accommodate for peoples size, which in turn will encourage people to wear them more often. Seat belt pretensioners retract the seat belt ‘slack’, almost instantly, in a crash. Rear-centre shoulder belts are added features, onto the already required ‘lap’ belt. Depending on the speed at impact and the stiffness of the object struck, front air bags inflate to prevent occupants from hitting the dashboard, steering wheel, and windshield. Side air bags reduce the risk that occupants will hit the door or objects that crash through it. Side air bags also provide additional chest protection by inflating instantly during many side crashes; some, also provide head protection.Anti-lock breaking systems prevent a vehicle's wheels from locking during "panic" braking and allow the driver to maintain steering control as the vehicle slows (which is a key factor in avoiding a collision).Traction control systems improve vehicle stability and steering control during acceleration by controlling the amount the drive wheels can slip when you apply an excess amount of power.According to Newton’s first law, that the occupant would have the same constant motion unless acted on by an unbalanced force, if we didn’t have seat belts or Air bags, we would keep going through the windshield. Also without ABS brakes the momentum would keep the ca...
