Why is overdriving your headlights dangerous at night?

You can drive faster than the speed limit
You may not see pedestrians
You potentially cannot stop within the distance you can see
You may run out of fuel

The correct answer is: You potentially cannot stop within the distance you can see

Overdriving your headlights is particularly dangerous at night because it means that you are driving at a speed that is greater than what you can safely see ahead. Headlights illuminate a limited area in front of your vehicle; if you exceed the speed at which you can react to obstacles within that illuminated zone, you may encounter a situation that requires you to stop or maneuver without having enough time or distance to do so safely. This greatly increases the risk of collisions since you won’t be able to respond effectively to sudden obstacles, such as other vehicles, road hazards, or animals. While not being able to see pedestrians or running out of fuel can also present risks, the fundamental issue of overdriving headlights is primarily about the relationship between speed and visibility. At night, the limited illumination means that drivers must adjust their speed appropriately to ensure that they can stop in time for any unforeseen obstacles.
