What does this sign mean?
En español: ¿Qué significa esta señal?
Why this is the correct answer
Indicates a lane reserved exclusively for certain types of vehicles (buses, motorcycles, three-wheeled vehicles assimilated to motorcycles, taxis, cycles, etc.). The symbol of the authorised vehicle type or types will be shown on the sign. On sections where the longitudinal lane marking is a broken line, use of the lane by other vehicles is permitted only to perform a manoeuvre other than stopping, parking, U-turning or overtaking, and priority must always be given to vehicles authorised to use this lane.
