Illuminated instructions displayed by police vehicles

Drivers must obey illuminated warnings and instructions displayed by police vehicles. If a police vehicle overtakes you with its siren operating, moves ahead and displays 'ACCOSTARE' (pull over), you must pull over and stop. If it displays 'ALT POLIZIA' (police stop), the order applies specifically to you. 'INCIDENTE' warns of an actual incident and requires you to slow down; it does not merely label the area as statistically collision-prone. 'RALLENTARE' applies to all affected traffic, not only heavy vehicles. Follow every instruction promptly and safely.
