Which driving action is crucial for maintaining safety during nighttime driving?

Reducing your speed during nighttime driving is essential for maintaining safety due to several factors related to visibility and reaction time. At night, the reduced visibility can make it difficult to see obstacles, pedestrians, or other vehicles in the road ahead. Slower speeds give you more time to react to unexpected situations, such as animals crossing the road or a sudden stop by a vehicle ahead.

Additionally, driving at a lower speed allows for better control of the vehicle, which is particularly important when navigating curves or poorly lit areas. It also helps mitigate the reduced distance you can see in the dark, ensuring that you're able to stop in time if necessary. In contrast, using excessive turn signals, relying solely on parking lights, or driving with no lights at all can lead to confusion, decreased visibility, and increased risk of accidents.
