What do the V16 symbols on safety beacons mean? Origin and regulations
V16 beacons are revolutionizing the way drivers handle roadside emergencies. This new warning device replaces the old warning triangle with a much safer, more visible, and more connected alternative. 🚨 But what exactly does V16 mean? Why is it becoming mandatory in all vehicles?
Below, we explain everything about its origin, regulations, and how our Hero Driver LED IoT connected beacon meets all the requirements... and even goes beyond!
What does V16 mean?
The acronym "V16" is the official designation of the Spanish Directorate General of Traffic (DGT) for luminous hazard warning devices. These beacons are designed for use in the event of a breakdown or accident, allowing other drivers to be quickly alerted and increasing road safety.
Unlike the traditional triangle, which requires you to exit the vehicle and walk part of the way across the road, the V16 warning light can be easily attached to the car's roof without having to leave the passenger compartment. This significantly reduces the risk of being hit.
Origin of the V16 beacons: A necessary evolution 📈
Warning triangles have been mandatory in vehicles for decades, but with the passage of time and the increase in accidents caused by their installation, the DGT has considered safer alternatives.
In 2021, an amendment to the General Vehicle Regulations was published authorizing the use of V16 devices as a valid and safe option. Since then, they have grown in popularity due to their ease of use, visibility, and built-in technology.
Starting January 1, 2026, connected V16 beacons will be mandatory, permanently replacing emergency triangles, according to current Spanish regulations.
Legal requirements for V16 beacons
Not all beacons on the market meet the requirements established by the DGT. According to regulations, for a V16 beacon to be legal and approved, it must have the following key elements:
- Flashing yellow light with a 360º field of visibility.
- Minimum visibility of 1 kilometer away.
- Operation without leaving the vehicle.
- Approval through the Ministry of the Interior.
And, starting in 2026:
- Obligation to have connectivity with DGT 3.0 to automatically broadcast the vehicle's location in case of emergency.
