Skid plate

A skid plate is an abrasion-resistant material affixed to the underside of a vehicle or boat[1] to prevent damage to the underside when contact is made with the ground.

Skid plates may be used on off-road vehicles, motorcycles and lowered vehicles to prevent damage to the underside.

Fake skid plates are also added to vehicles for an off-road look.
