Luci rosse lampeggianti

When in operation, they flash alternately and prohibit the passage of vehicles and pedestrians, requiring them to stop and not cross the transverse stop line. They may be found at railway level crossings with half-barriers or without barriers, at the entrance to a ferry embarkation ramp or a movable bridge, and when aircraft are landing or taking off (supplementing the LOW FLYING AIRCRAFT danger sign). Normally, they are located on the right side of the road and are integrated with an acoustic signaling device. At level crossings, they are positioned in the immediate vicinity of the tracks and activate shortly before the arrival of the train, prior to the lowering of the half-barriers, and remain on until the train has completely passed. Therefore, when approaching a level crossing with alternating flashing red lights and the half-barrier still raised, the driver must prepare to stop. It is not true that they are found near a police checkpoint, along railway lines as signals for train drivers, 150 metres before a level crossing, or on the first of the distance marker boards.
