Since 1 January 2026, Spanish rules recognise the connected V16 beacon as the device for warning other road users when a vehicle is immobilised. A flashing light that looks like a V16 is not automatically valid: the exact model must be certified and connected under the applicable requirements. Check the DGT list of certified brands and models before buying.
What a connected V16 does
The beacon gives a visible warning to approaching traffic and, when activated, sends the location of the immobilised vehicle to the traffic platform. It contains its own location and communications components. You do not need to install a phone app or register the device for it to send that location. The connection does not identify the vehicle’s occupants.
From 2026, an unconnected V16 is no longer a valid legal warning device in Spain. Check the exact model against the certified list, because not every product marketed as “connected” meets the requirements.
Where to keep it and how to place it
Keep the beacon inside the vehicle where the driver can reach it easily, and check its battery or the expiry date specified by the manufacturer. If you break down, use the vehicle’s hazard lights when appropriate and activate the beacon according to its instructions. Place it at the highest possible point on the vehicle so it can be seen from a distance; the rules require maximum visibility.
The practical advantage is that you can position it without walking along the carriageway to the boot to set out warning triangles. Even so, do not put yourself in danger. Follow DGT safety guidance, move to a protected place if you can, and contact emergency or breakdown services when needed.
What to do if the vehicle stops
Put people first. If it is safe, move the vehicle out of traffic lanes; avoid standing exposed beside moving traffic and guide passengers to a protected area. Activate the beacon and request assistance. On a motorway, do not attempt a repair in a dangerous place; wait for help somewhere safe.
A warning light does not replace emergency calls or basic self-protection. If anyone is injured or there is an immediate danger such as fire, call 112.
Check before you buy
Confirm the brand and model on the DGT list of certified devices, keep the beacon accessible and make sure it is ready to work. Do not rely only on a product name or a flashing lamp: certification and connectivity determine whether the model is valid. Consult the official DGT page if the rules change or you are unsure how to use it.
