What precaution should be taken when driving at night?

When driving at night, it is crucial to recognize that visibility is significantly reduced compared to daytime driving. Lowering your speed is essential because it gives you more time to react to unexpected obstacles, pedestrians, or changes in road conditions that may not be as visible in the dark. A greater following distance is equally important; in low-light conditions, it can be challenging to judge distances accurately. By maintaining a greater distance from the vehicle ahead, you increase your reaction time and reduce the risk of a collision.

Using the same speed as one would during the day can lead to dangerous situations, as it limits your ability to respond to hazards that may arise in the limited visibility of nighttime driving. High beams can also create hazardous situations for oncoming traffic and might not be appropriate for all areas, while reducing mirror use could severely hinder situational awareness. Therefore, option A reflects the best practices for ensuring safety while driving at night.
