When driving at night, you should:

• A. Drive faster to reach your destination quickly
• B. Rely on streetlights
• C. Adjust speed so you can stop within the distance of your headlights
• D. Use high beams in traffic

Answer: (C)

Night driving demands adjusting your speed so you can stop within what your headlights illuminate ahead. Your total stopping distance includes how long it takes you to perceive a hazard, react, and then brake. Because visibility is reduced at night, you can’t safely stop as quickly as you might in daylight, so you should slow down to a speed that allows you to stop if a hazard appears within the illuminated distance.

Relying on streetlights isn’t enough, since their light doesn’t reach far or evenly enough to reveal every hazard. Using high beams in traffic can blind other drivers and reduce everyone’s ability to see—so only use low beams when other vehicles are nearby. In short, drive at a pace that matches how far your headlights let you see and stop.
