When approaching a road construction site with a signal person, you should:

• A. Obey the signal person's instructions at all times.
• B. Ignore them if traffic is light.
• C. Only follow when a stop sign is present.
• D. Slow down but do not stop.

Answer: (A)

When approaching a road construction site with a signal person, you must follow their instructions at all times. The signal person is there to protect workers and coordinate traffic through the work zone, and their signals take precedence over other signs or signals inside that area. Respond promptly to their directions—stop when they indicate, proceed only when told to go, and slow to a safe, controlled speed. Even if traffic is light, construction equipment and workers can move unexpectedly, so complying reduces the risk of a crash. Ignoring the signal person or relying on a stop sign or normal traffic flow can create dangerous situations for everyone in the zone.
