¿Qué señal utilizará un agente en su vehículo para señalizar que la calzada vuelve a estar abierta a la circulación?

To show that the carriageway is open to traffic again, the officer will use a green flag. A red flag shows that, once the vehicle carrying it has passed, the carriageway is temporarily closed to all vehicles and road users, except those accompanied or escorted by officers of the authority responsible for regulating, managing and controlling traffic. A yellow flag tells other drivers and road users that they must pay extreme attention or that a danger is near. This flag may also be used by authorised auxiliary staff who carry out order, control or safety duties during cycling events or any other activity, sporting or not, on roads covered by traffic law.
