What does the concept of never overdriving your headlights at night mean?

The concept of never overdriving your headlights at night refers to the idea that drivers should always maintain a speed that allows them to stop comfortably within the distance illuminated by their headlights. This is crucial for safety, as it ensures that you can react to obstacles or hazards in your path without exceeding your ability to see and respond in time. Overdriving your headlights can lead to accidents, as it reduces your reaction time in low visibility conditions. Therefore, it's essential to adjust your speed to stay within the limits of your vehicle's lighting.
