What does the term 'overdriving your headlights' mean?

The term 'overdriving your headlights' specifically refers to a situation where a driver is traveling at a speed that exceeds the distance illuminated by the vehicle's headlights. This means that the driver cannot stop in time to avoid an obstacle that is visible only within the range of the headlights. When driving at night or in low light conditions, it is critical to maintain a speed that allows for adequate reaction time, as the visibility provided by headlights is limited.

If a driver is moving faster than the distance they can see ahead, they may encounter hazards without enough time to react, increasing the risk of a collision. This concept underscores the importance of adjusting speed according to visibility conditions to ensure safety on the road.

The other options do not accurately describe the phenomenon. Driving slower than the speed limit does not relate to the capabilities of the headlights. Operating with high beams may improve visibility but doesn't directly address the issue of overdriving. Driving when visibility is poor is a broader concept that also doesn't specify the relationship between speed and headlight range.
