When traffic lights are out of order, no one has priority by default. Drivers should treat the junction as an unmarked crossroads and proceed with caution, giving way where necessary. Typically, the rule is to give priority to the vehicle that arrives first, and if two vehicles arrive simultaneously, the one on the right has priority. Pedestrians in crosswalks generally have priority over vehicles. Drivers should also slow down, look carefully for other road users, signal their intentions early, and proceed only when it is safe to do so. If there are main roads or "priority roads" marked, normal right-of-way rules for those roads apply. If police or traffic officers are present, their directions override these rules.
