The General Directorate of Traffic is increasingly Fixed and section control devices on Spanish roadsaccording to Interior Minister Fernando Grande-Marlaska.
Both fixed radars, and those of section, must be previously marked. However, mobile radars do not have the obligation to position a signal to specify their position, although there are posters that They report the possibility of being in a certain sectionas the yellow signal S-991 g.
What does S-991G notes refer to?
According to him Catalog of vertical circulation signals Posted by the Ministry of Interior, this signage “Indicates the possible existence in the stretch of speed controls through aerial media, such as helicopter or drone. In the event that these controls have a specific vehicle type, the signal may include only the pictogram corresponding to said vehicle! ”

What characteristics do Pegasus helicopters have?
These helicopters have the MX-15 radar, capable of identifying excess speed from a height of 300 meters and a distance of up to 1 kilometer of the offending vehicle. As explained by the DGT, the process begins when the helicopter is located on the car and, thanks to its integrated GPS, determines its coordinates. Next, the Radar MX comes into operation using a laser telemeter, which accurately measures the distance between them.
In this way, when registering the successive positions of the vehicle, The system can calculate its speedsince it takes measures every three seconds and obtains an average. Finally, it should be noted that all infractions are recorded on video and communicate to drivers telematically.
Can the Pegasus report at night?
To begin with, it is important to note that DGT helicopters have the ability to patrol during the night to supervise the country’s roads. However, the Radar MX-15 that incorporate these pegasus does not have infrared technologywhich prevents it from operating at night, unlike fixed and mobile radars, which can do so.
In summary, DGT helicopters require optimal visibility conditions for their speed control system to function properly. In addition, it is relevant to mention that, in adverse weather situations such as The rain or fog, Pegasus usually remains on land And it does not go to patrol
