When driving at night and using high beams, when should you dim your lights?

Answer: B — Within 200 ft of the vehicle you're following

Dimming your lights when driving at night is essential for the safety of both yourself and other road users. The correct guideline is to dim your high beams within 200 feet of the vehicle you’re following. This distance is important to prevent blinding the driver in front of you, which can lead to dangerous situations, as high beams can create glare that obscures their view of the road. Maintaining a safe distance when dimming your lights helps ensure that other drivers can see clearly and navigate safely, especially if they are on a two-lane road or in low-visibility conditions. It also fosters a respectful driving environment where all motorists can operate their vehicles without unnecessary interference from others' headlights. In contrast, the guidelines for other options can be less effective for this specific scenario. Recognizing when to adjust your lights enhances overall road safety, particularly in maintaining proper visibility for everyone on the road.
