Bonjour,

Sur des véhicules pour éviter de s'enliser dans le désert.

"Sand channels are long metal strips and are often stowed on the sides of desert vehicles. Sand mats are bamboo and canvas contrivances that can be rolled up for easier storage, but they need an active non-driver to pull them taut to give them tension. Both mats and channels are positioned in front of the wheels and provide support for the vehicle to climb out of the sand."

Merci d'avance.
