When driving at night, what should you adjust to ensure safety?

Adjusting your speed to keep stopping distance within sight distance is crucial for safe driving at night. This is because visibility is significantly reduced in the dark, which means you have less time to react to obstacles or hazards on the road. By matching your speed to the distance you can see ahead, you can ensure that you have sufficient time to stop safely if necessary.

For instance, if your headlights illuminate a certain distance, but your speed is too high, you may not be able to stop in time if something suddenly appears in your path. Maintaining a slower speed helps ensure that you can react appropriately to any unexpected situations you may encounter after the light from your headlights ceases to illuminate the road.

Other considerations such as adjusting your steering wheel position, headlight brightness, or rearview mirror angle, while they can enhance comfort or visibility, do not directly address the immediate concern of maintaining a safe stopping distance in low visibility conditions.
