You see a signal person at a road construction site ahead. You should obey his or her instructions:

• A. At all times.
• B. Only when you pass through the intersection.
• C. Only during daytime.
• D. Only in bad weather.

Answer: (A)

In work zones, a flagger has authority to control traffic and keep workers safe. Their signals or directions take precedence over traffic lights, signs, or other rules, so you must follow them immediately. This means obeying the signal person at all times, whether it’s day or night or the weather is good or bad, because any deviation can create a dangerous situation for you and others. The other options imply you can ignore the instructions under certain conditions, which is unsafe in a construction zone; always let the flagger guide your movement. If you’re ever unsure what a signal means, slow to a stop and wait for a clear, explicit instruction from the flagger.
