You are about to descend a long, steep grade in a loaded tank vehicle. Why should you select a low gear before starting down, even more deliberately than in a dry van?

Pick an answer

1. Combining a downhill grade with liquid surge can build speed faster than the brakes alone can safely manage
2. Tank vehicles are exempt from normal grade descent rules because their brakes are built to a higher standard
3. Low gears are only useful for climbing, not descending
4. A low gear has no particular benefit for tank vehicles
