What is the main concern of overdriving headlights?

Overdriving headlights refers to a situation where a driver is traveling at a speed that exceeds the distance illuminated by their vehicle's headlights. This is a significant concern primarily because it leads to reduced visibility in low light conditions. When you overdrive your headlights, you cannot see far enough ahead to react appropriately to obstacles, pedestrians, or other vehicles, increasing the risk of accidents.

Inadequate visibility means that even if you are in a well-maintained vehicle, the lack of sufficient light can create dangerous driving conditions. This highlights the importance of adjusting your speed to ensure that you can stop within the distance illuminated by your headlights, particularly at night or in poor weather conditions. Taking this into account helps in maintaining safety on the road during less than ideal driving conditions.
