Lower your headlight beams when following another vehicle within ___ feet.

• A. 300
• B. 600
• C. 200
• D. 1000

Answer: (A)

When you’re driving at night, your high beams should be lowered as soon as you’re close behind another vehicle so you don’t glare into the driver's eyes. This keeps the driver ahead from being blinded and helps both of you see the road clearly. The standard distance for this is three hundred feet; staying on high beams within that range can obscure the lead car’s taillights and reduce their ability to react to hazards. By dimming your lights, you give the following driver a better view of their lane and any obstacles ahead, which is safer for everyone. If there’s no vehicle ahead within that distance, you can use high beams to maximize your own visibility, but switch to low beams as soon as you’re within range of other vehicles or if an oncoming car is near.
