There are just a few months left until the date many drivers have marked in red on their calendars: when the emergency warning light comes into effect. Soon, it will be mandatory to comply with the new signaling regulations in the event of an accident or breakdown, a pioneering measure in Spain that promises to change road safety, just as seatbelts and airbags did in their day.
Do you already know when it's mandatory to use the V16 hazard warning light ? Don't worry, in this post we'll explain what the DGT says, when it's mandatory, and how to ensure you comply with the regulations without errors.
What does the DGT say about the mandatory use of emergency lights?
The General Directorate of Traffic (DGT) establishes that the connected V16 emergency light will permanently replace warning triangles starting January 1, 2026. This measure is part of the new roadside assistance regulations to improve safety, reduce accidents, and allow immediate location of the stopped vehicle thanks to its automatic connection to the DGT 3.0 platform.
Currently, its use is voluntary but recommended, and since 2021, it can be legally used instead of triangles, provided it is certified and meets the conditions established by traffic regulations.
Motorhomes, on the other hand, must now have the V16 light, according to the DGT.
Is the V16 emergency light mandatory on all vehicles?
From 2026, it will be mandatory for passenger cars, vans and for all land vehicles registered in Spain, with the exception of motorcycles and mopeds. Until then, drivers can continue to use triangles if they wish. However, more and more drivers are choosing to anticipate and carry a warning light connected to avoid risks in an emergency.
Since when is it mandatory to have the V16 light on the car?
The requirement will come into effect on January 1, 2026. From that date, triangles and analog beacons (those not connected to the traffic cloud) will no longer be permitted, and only V16 beacons connected and certified by the DGT may be used.
Does the V16 light replace the emergency triangle?
Yes. The connected V16 beacon is designed to replace emergency triangles , improving visibility from a greater distance and activating without having to get out of the vehicle. Additionally, by sending the location of the stopped vehicle to the DGT (Directorate General of Traffic), it allows other drivers to be alerted in real time via information panels or navigation apps.
Should emergency lights be used in tunnels or on highways?
Yes. In tunnels, highways, and any other high-speed road, visibility is key to avoiding accidents . The V16 warning light provides a flashing light that's especially visible in low-light conditions or without natural light, making it an even more useful tool in these types of environments. Plus, you don't need to walk along the hard shoulder to place it, like triangles do, significantly reducing the risk of being run over.
Should I turn on my hazard lights if I stop due to a breakdown?
Yes, whenever you stop due to a breakdown, accident, or other roadside emergency, you must signal your position to avoid endangering other drivers. The V16 light is the quickest and safest way to do so.
Where should the emergency light be placed to be effective?
The beacon should be placed on the vehicle's roof, preferably as high as possible, to ensure maximum visibility in all directions. Models like Help Flash feature a magnet for quick and effortless attachment, but if the vehicle is made of any other material, it's also suitable, as it's designed to stay firmly on flat surfaces.
Do I have to get out of the car to activate the V16 beacon?
No. That's one of its great advantages. You can activate the beacon from inside the car and place it directly on the roof by sticking your arm out the window without exposing yourself to traffic. This simple gesture eliminates having to walk on the shoulder and increases your safety.
What is the fine for not using the emergency light correctly?
Starting in 2026 (when it becomes mandatory), if you fail to signal a breakdown or accident with an approved connected beacon, you could face a fine of up to 200 euros . Furthermore, using an unapproved beacon also carries a fine. That's why it's important to ensure the device complies with current regulations, for example, that it's connected to DGT 3.0.
Which vehicles must have V16 emergency lights?
All land motor vehicles that were previously required to carry triangles will now be required to carry a connected beacon starting in 2026, including cars, vans, trucks, and caravans.
In the case of motorcycles, it won't be mandatory, but compact models like the Help Flash IoT have been specially designed to take up as little space as possible, so they can be stored in the motorcycle's trunk and are highly recommended.
How do I know if my V16 light is certified by the DGT?
A connected and approved V16 light must meet the requirements of Royal Decree 159/2021 and be included in the official list published by the DGT. You can consult this updated list here:

In addition, the beacon itself must display the approval code, provided by one of the DGT-authorized laboratories, such as IDIADA or LCOE. We must also ensure that it specifies that it is a connected device; it generally contains the acronym #IoT, like our connected model Help Flash IoT+ .
In short, although its use is not yet mandatory, the connected V16 beacon is already the safest alternative for signaling a roadside emergency. Anticipating its mandatory use in 2026 allows you to drive with greater protection and comply with regulations designed to save lives. If you don't have one yet, be sure to purchase an approved and connected one. Your safety—and that of others—will thank you.
