What does the term "over-driving the headlights" mean?

The term "over-driving the headlights" refers to a situation where a driver is going faster than they can safely stop within the distance illuminated by their headlights. This often occurs at night or in low-light conditions when visibility is limited. When a driver exceeds the range of their headlights, they reduce their ability to see potential hazards, pedestrians, or other vehicles in time to react, increasing the risk of an accident.

In this context, the other options do not accurately capture the meaning of "over-driving the headlights." Utilizing headlights during the correct times (like between dawn and dusk), not turning off headlights near oncoming traffic, or driving on well-lit streets does not involve the concept of speed in relation to visibility limitations. Thus, option B distinctly addresses the critical safety concern posed by over-driving the headlights.
