The V16 Beacon in Spain (2026): What It Is, Who Needs It, and What the DGT Test Asks
Yes — since 1 January 2026, a connected V16 emergency beacon linked to the DGT 3.0 platform is the only legal way to pre-signal a breakdown or accident on Spanish-registered vehicles, and traditional warning triangles are no longer accepted as the standard signalling method. Only geolocated models that appear on the official DGT-approved list are valid, and not carrying one is a sanctionable offence. Foreign-plated vehicles passing through Spain are exempt.
What the V16 beacon is and why it replaced warning triangles
The V16 (señal V-16) is a small, magnetic, battery-powered light that you place on the roof of your car. Once activated it emits a high-intensity, 360-degree flashing amber light visible from a distance. The point of the device is simple but important: you can switch it on and place it on the roof without leaving the vehicle and without walking along the carriageway.
That last detail is the reason the V16 exists. Spain recorded repeated fatalities involving drivers struck while placing or retrieving warning triangles on motorway hard shoulders and in live lanes. The V16 removes the most dangerous part of signalling a breakdown — getting out of the car and walking into traffic. The DGT has therefore retired the triangle as the standard signalling method and made the V16 the legal replacement.
The 2026 version goes a step further than the early V16 lights sold from 2021 onward. It must be a connected device: when activated, it transmits the vehicle's location to the DGT 3.0 traffic-management platform in real time. The platform then warns approaching drivers through variable-message signs, navigation apps and connected vehicles, so traffic in the area knows there is a stopped vehicle ahead before they can see it.
When it became mandatory (effective date and grace period)
The obligation took effect on 1 January 2026. From that date, the connected V16 is the only valid pre-signalling device for vehicles registered in Spain, and warning triangles no longer satisfy the requirement on their own.
There was considerable public confusion about a "grace period." Before the deadline, statements from the Interior Ministry and the DGT suggested that drivers would initially be informed rather than fined. In practice, the DGT's director publicly confirmed there was no formal moratorium, on the grounds that the rule had been known for years, and some drivers reported being sanctioned within the first days of January 2026. The safe assumption for any Spanish-plated driver in 2026 is that the obligation is fully in force and enforceable now — do not count on leniency.
Who must carry one: Spanish plates vs foreign plates vs rentals
The obligation applies to vehicles registered in Spain — cars, vans, buses and mixed vehicles. If your vehicle has a Spanish plate, you must carry a compliant connected V16.
Foreign-plated vehicles in international circulation are exempt. Spain cannot impose a national signalling requirement that is not harmonised under international traffic rules on vehicles registered abroad. A tourist or foreign resident driving a foreign-plated car through Spain may continue to use the warning triangles (or equivalent device) required in their country of registration. The DGT still recommends carrying a V16 for safety, but it is not legally compulsory for those vehicles.
Rental cars are the trap for expats. A car hired in Spain almost always carries Spanish plates, which means the V16 obligation applies to it. The legal duty to carry a compliant device sits with the vehicle, so when you collect a Spanish rental you should confirm a connected, approved V16 is on board before you drive off.
| Vehicle | Connected V16 required? | Notes |
|---|---|---|
| Spanish-plated car/van/bus | Yes | Triangles no longer sufficient on their own |
| Foreign-plated (tourist) vehicle | No (exempt) | May use home-country triangles/device; V16 recommended |
| Rental car hired in Spain | Yes (Spanish plate) | Check the device is present and approved at pickup |
The 'connected' DGT 3.0 requirement explained
This is the part that catches people out, including those who bought a V16 in 2022 or 2023. From 2026, a light that simply flashes is not enough. The device must be connected and geolocated, with integrated connectivity (an embedded eSIM and GPS) that links it to the DGT 3.0 platform.
Older, non-connected V16 lights — the kind that only emit a flashing light with no data link — are no longer accepted as compliant from 1 January 2026. If you bought one before the connectivity requirement was finalised, it almost certainly needs replacing. Connectivity, including the data service, must be guaranteed for a defined minimum period under the regulation, so a compliant device should keep working without you paying a separate ongoing subscription.
A valid 2026 device must, broadly, provide a 360-degree high-intensity intermittent light for a sustained period, have a long battery shelf life, transmit its location to DGT 3.0 when activated, and appear on the official approved-models list.
How to check a model is on the official DGT-approved list
The authoritative source is the DGT's own "Dispositivos de preseñalización V16" page on dgt.es, which publishes the list of certified models. Devices are tested and certified by the authorised laboratories (such as IDIADA and LCOE) before they appear on that list. Practical steps:
- Check the model name and certification against the official DGT V16 list before buying — do not rely solely on a retailer's "homologada" label.
- Confirm the device is described as connected with DGT 3.0 geolocation, not just a flashing light.
- Be cautious with cheap or older stock: some previously sold beacons had their approval withdrawn or were never connected models.
- Keep any certificate or packaging reference in case of a roadside check.
Fines for non-compliance (and the figure confusion)
Not carrying a compliant signalling device is treated as a minor (leve) traffic offence. The figure most consistently reported by Spanish outlets and motoring organisations is a fine of around €80 — the same penalty that historically applied to not carrying warning triangles — often reducible with prompt payment. You may see higher figures quoted in some articles for related infractions; the commonly cited amount for simply not carrying a compliant V16 is €80.
Because exact figures depend on the specific infraction and can vary, treat the €80 as the widely reported baseline rather than a guaranteed single number, and check the current DGT sanction table if you need a precise amount. The same penalty logic applies if you carry a device that is not approved or not connected — an old, non-compliant beacon is treated as not having one at all.
Privacy and geolocation: what the beacon actually transmits
The connected V16 caused understandable privacy worry: a geolocated device that talks to a government platform sounds like tracking. Spain's data-protection authority, the AEPD, has publicly addressed this, and the reality is far narrower than the fear.
According to the AEPD's position:
- It does not transmit anything while switched off. The device only sends data when you activate it in an emergency.
- It does not identify you. When activated it sends the vehicle's location plus a technical identifier for the beacon — not your name, and not the number plate.
- There is no purchase registry linking you to the device. You do not hand personal data to any administration when you buy it, so the DGT does not know who owns a given beacon.
- It does not build a movement history. There is no continuous tracking; the signal exists only while the light is on and stops when you switch it off.
- Its functions are legally restricted. The regulation limits the device to two purposes — making the stopped vehicle visible and reporting the incident location to DGT 3.0 — and prohibits any other use.
In plain terms: the V16 is an emergency flare with a one-off location ping, not a continuous tracker following your trips.
How the V16 and pre-signalling devices appear on the DGT theory test
Equipment and signalling questions are a steady, scoreable part of the DGT theory exam, and the V16 is now firmly in scope. You will not be asked to memorise certification laboratories or fine amounts to the euro, but you should expect questions that test whether you understand the rule and the safe behaviour behind it. Likely angles include:
- Which device must be used to pre-signal a breakdown or accident — the answer is the V16, not the triangle.
- How to deploy it safely — placing it on the roof without leaving the vehicle or walking along the carriageway, ideally with your hazard lights on and a reflective vest worn before exiting if you must leave the car.
- What "connected" means — that the approved device transmits the vehicle's location to the DGT so other drivers can be warned.
- When and where to signal a stopped vehicle, and the general duty to warn other road users of an obstacle or hazard.
Treat the V16 the way you treat the reflective vest and other mandatory equipment: know what it is, when it is required, and the safe procedure for using it. Questions here are usually unambiguous once you understand the underlying safety logic — get out of traffic, signal without exposing yourself, and let the system warn others.
Next steps
If you drive a Spanish-plated vehicle, the practical action is straightforward: buy a connected, DGT-3.0-approved V16 from the official list, keep it accessible in the cabin (not buried in the boot), and know how to switch it on. If you drive a foreign-plated car, you are not legally obliged, but carrying one is sensible. For the exam, fold the V16 into your broader study of road signs, vehicle equipment and accident procedure rather than treating it as an isolated fact.
