What two factors can a driver adjust to control space in front of a vehicle when intending to stop?

To effectively manage the space in front of a vehicle when preparing to stop, a driver can adjust their speed and placement.

Speed refers to how fast the vehicle is moving. By reducing speed as the driver approaches a stopping point, they create more time and distance to react, allowing for a smoother, controlled stop. This adjustment is critical because it influences the stopping distance and the potential for a safe halt without sudden braking, which can lead to loss of control.

Placement involves the position of the vehicle within the lane or the distance from other vehicles or obstacles ahead. By properly positioning themselves, such as staying in the correct lane or maintaining a safe following distance, a driver can ensure they have ample space to react to changes in traffic conditions and avoid collisions.

Together, adjusting speed and placement provides a driver with the ability to maintain appropriate control over the vehicle and its surroundings, enhancing safety on the road.
