The DGT have started to use drones to monitor the traffic. After a successful pilot scheme in May, the drones will be introduced in Tenerife and Gran Canaria in the first two weeks of August. They will also be used throughout Spain on days known as Operation Salida o Operation Retorno when there are huge numbers of journeys too or from holiday destinations.
These drones are equipped with long-range, high-resolution cameras and are ideal for use in well-known trouble spots to monitor traffic and driver behaviour.
In addition to the drones, there will be at least nine helicopters patrolling the roads and motorways of Spain throughout the summer. Three of these are based in Madrid. With an increase in traffic movements, this means more use of the helicopters in the skies above us.
