What is an important factor to remember during nighttime driving?

Adjusting your speed according to visibility is crucial during nighttime driving because visibility is significantly reduced after dark. The ability to see obstacles, signals, pedestrians, and other vehicles is impaired under low-light conditions. By modifying your speed to match the visibility levels, you increase your reaction time and improve your overall safety while driving. This approach helps in accurately assessing the road, maintaining control of the vehicle, and reducing the likelihood of accidents.

Other approaches, such as using high beams exclusively or driving faster to reach your destination, can compromise safety. High beams can cause glare for oncoming drivers, and driving faster can diminish reaction times, further increasing the risk of accidents. Conserving battery by lowering headlights is not a practical consideration, as proper lighting is essential for safe driving at night.
