When meeting or following a vehicle at night, how many feet away should you dim your headlights?

Answer: D — 500 ft

When meeting or following a vehicle at night, it is important to dim your headlights to avoid blinding the other driver. Dimming your headlights reduces the glare and allows the other driver to see more clearly. A distance of 500 feet is recommended to dim your headlights, which is the correct answer in this case. This distance provides enough space for the other driver to maintain visibility without being affected by the brightness of your headlights. Options A, B, and C (100 ft, 200 ft, and 300 ft) are not the correct distances for dimming your headlights when meeting or following a vehicle at night. These distances are too short and may still cause glare and visibility issues for the other driver. The safest option is to dim your headlights at least 500 feet away from the vehicle you are meeting or following.
