In which scenario should you dip your lights?

Dipping your lights, or switching from high beams to low beams, is particularly important when passing another vehicle. This action helps to avoid blinding the driver of the other vehicle, which is crucial for road safety. High beams can create significant glare, and when you are nearing another car, reducing your headlights ensures that their visibility is not compromised, allowing both drivers to navigate safely.

When driving in the rain or in brightly lit areas, the necessity to dip lights might not be as pressing compared to the situation of passing another vehicle. On open highways, while it's also important to use high beams for better visibility, this should be adjusted when approaching other cars or during conditions that require caution. The key understanding here is that the practice of dipping lights directly addresses the safety of interactions with other road users, especially when they are within close proximity.
