Warning Triangles: How and When to Use Them Properly

Warning triangles are an essential road safety tool that all drivers should know how to use correctly. When used properly, they can save lives and prevent accidents on the road. In this article, we explain everything you need to know to be prepared for any roadside emergency.

What Are Warning Triangles?

Warning triangles are devices placed on the road to alert other drivers of a stationary vehicle due to a breakdown or accident. Their main purpose is to warn others and provide time to react, preventing collisions and ensuring greater safety for all road users.

Warning Triangles and Legal Requirements

Using emergency triangles is mandatory when a vehicle becomes immobilized on the road or shoulder of an interurban road. Two triangles must be placed, one in front and one behind the vehicle, at a minimum distance of 50 meters and visible from at least 100 meters away.

Exceptions:
On one-way roads or roads with three or more lanes in the same direction, only one triangle is needed behind the vehicle.

In adverse weather conditions or low visibility, it is recommended to increase the placement distance for greater effectiveness.

How to Safely Place Warning Triangles

Steps to properly use warning triangles:

• Park the vehicle safely, as close to the shoulder as possible, and turn on the hazard lights.
• Put on the reflective vest before exiting the vehicle, especially if you’re on a busy road.
• Place the first triangle 50 meters behind the car, on the same side of the lane.
• Place the second triangle 50 meters in front of the car if you’re on a two-way road.
• Avoid walking on the road: use the shoulder or the safest side of the road.

What Are the Risks of Using Warning Triangles?

Although useful, warning triangles require the driver to exit the vehicle, which can be dangerous, especially on highways or in poor visibility. According to the DGT, many accidents involving pedestrians have occurred for this reason in recent years.

The Future of Warning Devices: Connected V16 Beacons

What Is a V16 Light?

It is a light device placed on the roof of the vehicle without needing to step outside. The new connected V16 lights automatically send the vehicle’s location to the DGT 3.0 platform, improving emergency response and informing other drivers in real time.

Will They Replace Triangles?

Yes. As of January 1, 2026, warning triangles will no longer be mandatory and will be officially replaced by connected V16 lights. This change aims to eliminate the risk of pedestrian accidents by keeping drivers inside their vehicles during emergencies.
