When should you dim your lights for oncoming vehicles?

Dimming your lights for oncoming vehicles is important to ensure the safety and comfort of other drivers. The correct answer indicates that you should dim your lights when you are approaching from behind another vehicle. This is necessary because high beams can create a blinding glare and make it difficult for the driver ahead to see the road. By dimming your lights, you help maintain safe visibility for that driver, which is crucial in preventing accidents.

While dimming your lights when within a certain distance of oncoming vehicles or in residential areas may also be relevant, the most immediate action is in relation to approaching another vehicle from behind, as this can directly impact the driver's ability to function safely and effectively. Similarly, while considerations on driving at night on highways and in residential areas are important, they do not specifically address the immediate need to adjust headlights when interacting with other vehicles directly in your path.
