Overview
- The DGT rule makes the V16 warning beacon mandatory on motorways and expressways, retiring traditional triangles on those routes starting in 2026.
- Drivers can mount the flashing yellow light on the roof without leaving the vehicle, with visibility reported at up to about one kilometre.
- An integrated SIM sends the vehicle’s position to traffic authorities and emergency services roughly every 100 seconds only while the device is active, and it transmits location data only.
- The requirement applies to vehicles registered in Spain, so foreign‑registered private cars are not affected for now, while Spanish‑plated rental cars must be equipped.
- Retail prices are reported at about €30–€60, and triangles remain permitted on rural roads and in cities though the DGT recommends using the V16 there as well.
