Question: Scenario 77: You are approaching a sign that reads 'MAX HEIGHT 4.2 M'. What action should you take if your bus is 4.3 metres tall?

Answer options: ✅ Find an alternate route; your bus exceeds the maximum height limit.

• Proceed with caution, as this sign is advisory for non-commercial vehicles.
• Attempt to pass slowly, as the bridge clearance might be slightly higher.
• Assume the sign refers to the loaded height, not the bus's inherent height.

Correct answer: Find an alternate route; your bus exceeds the maximum height limit.

Explanation: A 'MAX HEIGHT' sign indicates a strict overhead clearance limit. If your bus's height exceeds this limit, you must not proceed and should find an alternate route to avoid a collision. The correct answer is "Find an alternate route; your bus exceeds the maximum height limit.".
