The DGT are currently studying possibilities of a provisional authorisation which would allow the change to start sooner, but as the entire process has taken years of work and effort, a wait until July is somewhat insignificant. Currently, in Spain, only the security services use blue lights, with ambulances and fire service vehicles using flashing amber lights when responding to an emergency. This reform will put Spain in line with the European standard for emergency vehicles. .
