What does the term "over-driving the headlights" best describe?

The term "over-driving the headlights" refers to a situation where a driver's stopping distance exceeds the distance illuminated by their headlights. This means that when driving at night, the driver may not be able to see far enough ahead to stop in time if a hazard appears within the range of the headlights. Typically, headlights provide a limited range of visibility, and if a driver is traveling too fast for this distance, they risk being unable to react appropriately to obstacles or changes in the road.

Understanding this concept is critical for night driving safety, as it emphasizes the importance of adjusting speed according to visibility conditions. By managing their speed, drivers can ensure that they have adequate reaction time to safely navigate potential hazards in darkness.
