Which statement about road work signs is most accurate?

Answer: C — They warn of workers, equipment, and possible lane changes; proceed with caution.

When you see road work signs, you’re entering a work zone where workers and equipment may be close to the roadway and traffic patterns can change. These signs warn you to slow down, expect possible lane changes or lane closures, and proceed with extra caution. You should reduce speed, increase following distance, and be prepared to stop or merge if needed, following any directions from flaggers or temporary signals. They’re not just about detours, and you shouldn’t ignore them even if traffic is light; you only stop completely if directed or if the situation requires a full stop. This is why the statement describing road work signs as warnings of workers, equipment, and potential lane changes with cautious driving is the most accurate.
