Before reaching the crest of a hill or entering a curve, you must _________ and watch for oncoming vehicles.

• A. Honk
• B. Accelerate
• C. Slow down and watch for oncoming traffic
• D. Turn on headlights

Answer: (C)

Limited sight distance at a crest or in a curve means you should slow down and scan for oncoming traffic before you reach the top or begin the turn. Slowing down gives you more time to see vehicles that might appear suddenly and to react, helping you stay in your lane and avoid a head-on or side-swipe collision. Honking isn’t a substitute for safe speed or watching for traffic, accelerating into the curve increases risk because you’ll have less time to react, and turning on headlights helps visibility but doesn’t address the need to reduce speed and actively look for oncoming vehicles.
