Drivers in Spain are preparing for the mandatory rollout of connected V16 emergency beacons starting January 1, and privacy concerns are plenty and causing widespread debate on social media. Many fear that the device’s geolocation features could allow the Directorate General of Traffic (DGT), or another body, to monitor vehicles in real time. However, officials and data protection authorities have firmly denied these claims, stressing that the beacons only transmit location data when activated during an emergency, and anonymously.
The V16 beacon, a compact flashing light designed to replace traditional warning triangles, has become one of the most controversial road safety measures in Spain. From next year, most vehicles will be required to carry a connected version of the device, which not only emits a high-intensity amber light supposedly visible from afar but also sends the vehicle’s position to the DGT’s 3.0 platform.
Does the V16 beacon inform on where you have been?
Rumours circulating online have led to widespread anxiety, with some drivers worried about constant surveillance or potential fines based on beacon data. Insufficient initial communication from the DGT has only added fuel to the fire, leaving many questions unanswered for too long, until recent clarifications.
Experts explain that the beacons cannot track drivers continuously. Equipped with IoT technology and a built-in SIM card, they provide geolocation capability across Spain’s road network, but only activate transmission when the driver manually turns on the device in case of a breakdown or accident.
V16 stops transmitting location when switched off
The Spanish Data Protection Agency (AEPD) addressed these concerns in an official statement: “The beacon transmits a signal only while it is switched on and stops when turned off, without generating movement histories or sending data continuously.” The agency stressed that the location data is fully anonymous, with no link to the driver, vehicle registration, or personal information.
When a driver activates and places the V16 beacon (typically on the roof of a vehicle), it takes about 100 seconds to connect to satellites. The signal then routes through the manufacturer’s cloud – provided by telecom companies – before reaching the DGT 3.0 platform. From there, it alerts relevant traffic authorities.
Crucially, the system is designed solely for safety: to warn other road users via variable message signs, navigation apps, or traffic management systems about a stranded vehicle, reducing the risk of secondary accidents. Around 25 people die annually in Spain from being struck while placing warning triangles; the V16 allows signalling without leaving the vehicle.
New rules under scrutiny
However, many are not convinced, citing accidents caused due to the beacons being insufficiently visible. Many also question the new advice of passengers remaining inside the vehicle awaiting a tow truck or emergency services. Recently a 2-year old child was killed in the UK when set in a broken down car when another vehicle slammed into the back of it.
The AEPD and DGT both highlight that purchasing a V16 requires no personal data registration with authorities, ensuring anonymity. The signal sent includes only the location and a technical device identifier, untraceable to individuals.
