What should you do if you encounter a construction zone with workers present?
Answer: A — Slow down and drive cautiously through the construction zone.
Encountering a construction zone with workers present requires cautious driving for both the safety of the workers and other drivers. Speeding up to clear the construction zone quickly (Option B) can be dangerous, especially if there are workers on the road. Following the instructions of workers regardless of traffic signals (Option C) is also unsafe, as traffic signals are put in place for the safety of everyone on the road. Lastly, sounding your horn (Option D) in this situation is not necessary and can startle the workers, potentially causing accidents.
