When should headlights be dimmed?

Answer: C — For oncoming traffic and when following another driver

Dimming your headlights is necessary to ensure safety and visibility for other drivers. Headlights should be dimmed for oncoming traffic, as bright headlights can create glare that impairs the vision of drivers coming from the opposite direction. This is especially vital during nighttime driving when the contrast between dark surroundings and bright lights is most pronounced. Additionally, when you are following another driver, it is also important to dim your headlights. High beams can reflect off the vehicle in front of you, causing glare that distracts the driver ahead and can lead to potentially hazardous situations. By dimming your headlights in these specific scenarios, you contribute to safer driving conditions for everyone on the road, helping to prevent accidents and ensuring that all drivers can see clearly. This practice is aligned with defensive driving principles aimed at promoting safe driving habits.
