Question: During a typical shift, an articulated hauler operator notices that the brake temperature warning light illuminates frequently when descending a particular 8% grade. What immediate action should the operator take?

Answer options:

• Increase speed to cool the brakes with airflow.
• Shift into a higher gear to reduce engine braking. ✅ Stop the truck in a safe location, allow brakes to cool, and report the issue.
• Continue operating, as warning lights are common on steep grades.

Correct answer: Stop the truck in a safe location, allow brakes to cool, and report the issue.

Explanation: A brake temperature warning light indicates overheating. The operator must stop immediately in a safe location to allow brakes to cool and prevent damage, as per manufacturer guidelines and safety protocols (Ontario Reg 213/91).
