What it means
The R-415 sign indicates a carriageway for vehicles carrying products that pollute water. It orders those vehicles to use the signed carriageway when affected by that load, channelling their route along the planned itinerary. It usually appears at links, diversions, or accesses where this transport is separated from other routes for protection and organisation reasons. When you see it, if you drive a vehicle carrying those products you must follow the indicated carriageway; if not, respect the reservation and avoid occupying it improperly. In the test it is often distinguished from the sign prohibiting entry to those vehicles: this one requires following a specific path.
