What should drivers do when they encounter a sign indicating a construction zone?

Answer: C — Slow down and be prepared to stop.

When drivers encounter a sign indicating a construction zone, it is crucial to slow down and be prepared to stop. Construction zones often have reduced speed limits to ensure the safety of both the workers and the motorists. By slowing down, drivers not only adhere to the law but also allow themselves sufficient time to respond to any sudden changes in traffic patterns or unexpected obstacles that may arise due to construction activities. Additionally, construction zones can feature workers, equipment, and other vehicles that pose potential hazards, making it essential for drivers to remain vigilant and cautious. Being prepared to stop is vital in these situations as conditions may change unexpectedly, and it shows a responsible attitude towards traffic safety. Maintaining caution in construction zones helps to protect both the workers present and other drivers, reinforcing the importance of safe driving practices around these areas.
