For many drivers in Spain, the V16 emergency beacon was supposed to be a simple safety upgrade. Switch it on if you break down, alert other road users automatically, and avoid stepping into live traffic with a warning triangle. Straightforward enough.
Except things haven’t quite gone to plan.
In recent days, a privately created online map showing the real-time location of activated V16 beacons has started circulating online – and it has raised more than a few eyebrows. The map pulls data linked to the DGT and allows anyone to zoom into a town, motorway or rural road and see where a beacon appears to be active, including the stretch of road and the time it supposedly switched on.
At first glance, it feels like clever technology. Look a little closer, and some drivers are starting to feel uneasy. If anyone can see where stranded vehicles are located, what’s stopping the wrong people from using that information too?
Concerns have only grown after television reporters discovered something even more puzzling: some vehicles were appearing on the map even though their V16 lights had never been activated.
When the map shows a beacon that was never switched on
A team from Antena 3’s programme Y ahora Sonsoles decided to test the map for themselves. On screen, they spotted several beacon locations clustered within roughly 20 kilometres of each other and headed out to see what was actually happening on the ground.
The first stop led them to a car pulled over on the road. When the reporter asked the driver if he knew how the map had located him so quickly, he admitted he was familiar with the system – but hadn’t even had time to take the beacon out of the car yet. Despite that, his vehicle was already showing up online.
The second marker took the team to an empty stretch of road. No broken-down car, no flashing light, no obvious incident at all. A third point led them to a lorry stopped with its hazard lights on, but again, no V16 beacon in use. In a fourth case, the driver said he owned the device but hadn’t even unpacked it from the box.
It left a lot of people scratching their heads. If the beacon isn’t switched on, how can a location appear on the map at all?
Social media quickly filled with speculation. Some motorists began worrying that the devices might be transmitting constantly. Others joked nervously about wrapping their beacon in aluminium foil just in case – half humour, half genuine concern.
The bigger worry, though, is what this kind of visibility could mean in the real world. A public map showing stranded vehicles could potentially make life easier for scammers, including fake recovery trucks that target drivers when they’re already stressed and vulnerable.
Cybersecurity experts explain what may really be happening
To clear up the confusion, the programme spoke to cybersecurity expert Miguel López. His first point was to calm some of the fears. The system does not track people, and no personal data is being shared. What’s visible is simply a vehicle location linked to a traffic incident.
But López also acknowledged that making this type of information so accessible can create opportunities for abuse. If criminals can easily see where vehicles are stopped, it could make certain scams easier to organise.
The key detail many people missed is that the map itself is not an official DGT platform. It was created by a private individual using available traffic data. That matters, because the map may be mixing different sources of information together.
According to López, the V16 beacon cannot transmit anything unless a driver actively switches it on. If vehicles appear on the map without a beacon being activated, the most likely explanation is that the map is also displaying other types of incidents detected by the DGT, such as reports from traffic cameras or patrols, but presenting them as if they were beacon activations.
In other words, the beacon probably isn’t secretly broadcasting anyone’s location. The confusion seems to lie in how the data is being interpreted and displayed.
That said, the episode has added another layer of doubt to a device that has already generated plenty of debate since becoming mandatory at the start of the year. Many drivers still feel unsure about how the technology works, what data is shared, and who can see it.
López also pointed out that similar location data has existed for years through navigation apps and traffic monitoring systems. What feels different now is visibility. When information becomes easily searchable on a public map, people naturally pay more attention to it — and sometimes imagine worst-case scenarios.
For drivers, the practical takeaway remains fairly simple. If you break down and someone approaches offering help, it’s worth staying cautious and verifying who they are, just as you would have done before the V16 era. Use official recovery services where possible and avoid sharing personal details at the roadside.
The V16 beacon was designed to improve safety and reduce risk on Spain’s roads. But as this latest story shows, even sensible technology can create fresh anxieties once it meets everyday reality. For now, many motorists are still getting used to the idea that a small flashing light can carry far more digital weight than anyone expected.
