Article 146 Traffic lights for vehicles

The meaning of their lights and arrows is as follows:


A) A non-flashing red light prohibits passage. While it remains on, vehicles must not pass the traffic light or the stop line closest to it, if there is one. If the traffic light is inside or on the opposite side of an intersection, vehicles must not enter it or pass the stop line located before it, if there is one.


B) A flashing red light, or two alternately flashing red lights, temporarily prohibit the passing of vehicles before a level crossing, an entrance to a moving bridge or a pontoon ferry, in the vicinity of an exit of fire extinction vehicles or due to the approach of an aircraft at a low altitude.


C) A non-flashing yellow light means that vehicles must stop under the same conditions as if they were a fixed red light, unless, when turned on, the vehicle is so close to the place of stopping that it cannot be stopped before the traffic light in a safe way.


D) A flashing yellow light or two alternately flashing yellow lights force drivers to exercise extreme caution and, if necessary, give way. Also, the driver is not exempt from compliance with other signals that force them to stop.


E) A green non-flashing light means that priority passing is allowed, except in the cases referred to in article 59.1.


F) A black arrow on a non-flashing red light or on a yellow light does not change the meaning of said lights, but limits it exclusively to the movement indicated by the arrow.


G) A green arrow that illuminates on a black background means that vehicles can take the direction indicated by the arrow.


Any vehicle that, when the green arrow lights up, is in a lane reserved exclusively for the movement in the direction indicated by the arrow or that, without being reserved, is the one that is moving in the lane, must advance in that direction.


Vehicles that advance following the indication of a green arrow must do so with caution, allowing vehicles passing through the lane to which they are entering to pass and not endangering pedestrians crossing the road.
