When does a school zone end?

• 500 metres from the start of the zone
• 250 metres from the start of the zone
• 150 metres from the start of the zone
• A traffic sign indicates a higher speed limit or the end of the zone.
  Explanation:

  "A school zone typically ends when you see a traffic sign indicating either a higher speed limit or the official end of the zone. Relying on specific distances (e.g., 150, 250, or 500 metres) is not accurate, as school zone lengths can vary."
