Which distance is correct for dimming when following another vehicle at night?

• A. 300 feet
• B. 600 feet
• C. 150 feet
• D. 500 feet

Answer: (A)

When you’re following another vehicle at night, switch to low beams within 300 feet of the vehicle ahead. This reduces glare for the driver in front while still letting you see the road ahead clearly, giving you enough time to react if they brake. Distances like 600 feet or 150 feet don’t fit this safety rule, and 500 feet is the distance for meeting an oncoming car, not for following. Dimming at 300 feet strikes the right balance between protecting the driver ahead from glare and maintaining your own visibility.
