What does the term 'overdriving your headlights' mean?

The term 'overdriving your headlights' refers to the situation where a driver is traveling at a speed that exceeds their ability to stop safely within the distance illuminated by their headlights. At night or in low-visibility conditions, headlights provide a limited field of view; if a vehicle is moving faster than what the driver can effectively see and react to, it becomes dangerous. For instance, if a car’s headlights only illuminate the road up to a certain point ahead and the driver is traveling faster than what can be illuminated, they may not have enough time to react to obstacles or hazards in their path, significantly increasing the risk of accidents.

This definition underscores the importance of adjusting speed according to visibility conditions, ensuring that drivers can safely navigate the road at night.
