Answer 1

When using headlamps to improve visibility, they must be dimmed 500 feet before meeting another vehicle and turned on before overtaking another vehicle.

Step-by-step explanation:

When headlamps are used to improve visibility, they must be dimmed 500 feet before meeting another vehicle and turned on before overtaking another vehicle. Dimming the headlamps helps prevent blinding the driver of the oncoming vehicle, while turning on the headlamps when overtaking ensures that the driver is aware of your presence. Flashing the headlamps can also be used as a communication signal, such as to indicate to the driver ahead that it is safe to merge into your lane.
