It is 9.20am on a school day. You are driving at 60 km/h, the same speed as traffic around you. You pass this sign but the other cars do not slow down much. What should you do?

• A. Slow down immediately to 40 km/h or less even though other drivers want to go faster.
  Explanation:

  "The speed limit is 40 km/h because there may be children around."
• B. Drive at the speed of the other drivers because it is safer to go with the flow of traffic than slow others up.
• C. Stay at 60 km/h because it is nearly 9.30am and the times on the school sign are only advisory.
