What is "over-driving your headlights"?

Over-driving your headlights refers to the scenario where a driver is traveling at a speed that exceeds the distance that their headlights can effectively illuminate the road ahead. This situation is particularly dangerous because it limits the driver's ability to see obstacles, hazards, or curves in the road, which can lead to an increased risk of collision or accident at night or in low-light conditions.

For example, if a vehicle is traveling at a high speed in a dark area where headlights only illuminate a short distance ahead, the driver may not have enough time to react to any sudden hazards they cannot see until it's too late. Thus, it's crucial for drivers to adjust their speed according to their visibility as provided by their headlights, ensuring they can stop or maneuver safely if needed.
