DGT Issues Warning on Key Differences Between V-2 and V-16 Road Safety Lights
Spain's General Directorate of Traffic is urging motorists to distinguish between V-2 maintenance lights and V-16 emergency beacons to improve road safety and incident response.
The General Directorate of Traffic (DGT) is reminding drivers of the important differences between V-2 and V-16 warning lights. Understanding these two signals is vital for road safety, as each requires a different response from other motorists.
The V-2 device is a rotating yellow light used exclusively by vehicles performing maintenance, construction, road assistance, or special transport. Under Article 113 of the General Traffic Regulations, these vehicles must use the light to warn others of potential hazards or traffic disruptions. Because these vehicles often move slowly or stop frequently, the light must be visible from at least 100 meters away in all directions. It is strictly illegal to install a V-2 light on a private passenger car unless the vehicle is specifically authorized for these services.
In contrast, the V-16 beacon is an emergency signal used when a vehicle is forced to stop due to a breakdown or an accident. While the V-2 identifies a vehicle that is actively working on the road, the V-16 alerts drivers to a stationary vehicle. Seeing a V-16 should prompt drivers to slow down immediately and exercise extreme caution to avoid rear-end collisions.
Knowing the difference helps drivers anticipate what lies ahead. When you see a V-2 light, you should expect a work zone or a service vehicle, meaning you should increase your following distance and reduce your speed. If you see a V-16 beacon, you are approaching a static incident and must take immediate precautions to stay safe. Correctly interpreting these signals is a key part of reducing accidents on our roads.
