When driving at night and dimming your headlights, it is important to slow down. Dimming your headlights is typically done when approaching other vehicles to avoid blinding the driver. Reduced visibility at night means you have less time to react to obstacles, road signs, or turns. Greater caution is essential, which often translates into driving at a lower speed.

Maintaining or increasing speed under these conditions can be dangerous, as your ability to see and react becomes compromised. It is crucial to ensure that you can stop in time if an unexpected situation arises, emphasizing the importance of adjusting your speed to match the lower visibility.
