What should a complete report of traffic control measures include?

Answer: B — Duration of the maintenance

A complete report of traffic control measures should include the duration of the maintenance because it provides essential information about how long the traffic control measures will be in effect. This detail is crucial for planning and communication with both drivers and local residents, as it allows everyone affected to understand the expected timeframe for the traffic conditions. Knowing the duration helps in managing expectations and ensures that both traffic management and public safety are adequately addressed. It is also important for coordinating ongoing operations and ensuring that any necessary follow-up or adjustments can be made within that timeframe.
