Lanes opened in the opposite direction to the usual one for reasons of traffic flow may only be used by motorcycles, with or without a sidecar, and passenger cars. However, when they are opened due to roadworks, all vehicles authorised to travel on the road may use them, including cars with trailers, unless expressly prohibited.
