When should you dim your lights to avoid blinding other drivers?

Dimming your lights is essential to ensure safety on the roads, especially when there are other drivers nearby. The correct moment to dim your lights is just before you would inadvertently blind another driver with your high beams. This typically occurs when you're approaching oncoming traffic or when you're following another vehicle closely, as the bright lights can be disorienting and dangerous for the other drivers.

While dimming your lights in various situations such as before entering a roundabout, changing lanes, or stopping may be relevant for visibility purposes, the critical point emphasized here is the need to specifically address the potential for blinding another driver. Choosing to dim your lights ensures that you remain courteous and safe, allowing for better visibility for everyone on the road.
