Gravel is necessary, but sand control is not necessary.

Gravel insurance is the damage caused by stones splashed up by the road surface to car windows, doors, and chassis, not including natural disasters. Sand prevention insurance is the damage caused to cars in situations such as sandstorms. This is what I understand. I welcome corrections and supplements.
