Overview
- The requirement applies to vehicles registered in Spain on motorways and expressways, with foreign-plated cars explicitly exempt.
- Warning triangles remain permitted on rural roads and in urban areas, so non-highway use is unchanged.
- V16 units attach to the roof without leaving the vehicle, use a strong magnet, and emit an orange signal visible up to roughly one kilometer.
- Upon activation, the device sends the vehicle’s position to the DGT via a built-in SIM with updates about every 100 seconds.
- Units sell for roughly €30–€60, and renters should verify Spanish-registered hire cars carry a compliant beacon to avoid fines of up to €200.
