If a driver is overdriving their headlights, what is an important consequence?

When a driver is overdriving their headlights, they are essentially driving at a speed that exceeds the distance they can see illuminated in the dark. This results in a situation where, if an obstacle suddenly appears on the road, the driver will not have sufficient time to react and stop safely. The stopping distance required at higher speeds increases, and without adequate visibility, this can lead to serious accidents.

This underscores the importance of adjusting speed according to the visibility provided by the vehicle's headlights to ensure safety. Therefore, understanding the implications of overdriving headlights is crucial for responsible driving, especially in low-light conditions.
