What keeps a driver in control of their vehicle during a sudden stop?

A driver remains in control of their vehicle during a sudden stop primarily because of seat belts. Seat belts are designed to secure the driver and any passengers in their seats, preventing them from being thrown forward or sliding around inside the vehicle during a sudden stop. This secure positioning allows the driver to maintain their grip on the steering wheel and continue to control the vehicle's direction even as the momentum changes rapidly.

While other technologies like anti-lock brakes and traction control systems play important roles in vehicle safety and stability, they specifically address issues related to braking and traction rather than directly helping with driver control during a sudden stop. Power steering, on the other hand, aids in maneuverability but does not directly influence stability during abrupt braking situations. Therefore, seat belts are crucial for ensuring that drivers remain securely in place, enabling them to respond effectively to the dynamic changes that occur during sudden stops.
