In Norwegian road safety and vehicle operation, how should a driver control speed when descending long, steep mountain passes to avoid brake overheating and failure?
Answer and explanation
Correct answer: A. Select a lower gear to use engine braking, reserving the footbrake for periodic firm speed adjustments
- Step 1: Continuous footbrake friction boils brake fluid and causes brake fade. Engaging a lower gear allows the engine's compression to hold back the vehicle, keeping wheel brakes cool for emergencies. Answer: Select a lower gear to use engine braking, reserving the footbrake for periodic firm speed adjustments. Why not the others: the alternative options do not accurately reflect vehicle safety standards, statutory requirements, or physical mechanics under Norwegian road regulations.
