Where do you put the V-16 beacon?

As high as possible on the vehicle, normally on the roof, so it is visible without the driver stepping onto the carriageway. Not on the windscreen or the dashboard, and there is no need to walk 50 metres up the road as with triangles.

Is there a V-27 sign or a V-27 beacon?

No V-27 or V-23 appears in any of the 12,154 approved questions in our bank. The luminous pre-signalling device named by the rules is the V-16, in its version connected to the DGT 3.0 platform.

Do I still need warning triangles in Spain?

From 2026 the connected V-16 replaces triangles as the mandatory way to pre-signal an immobilised vehicle. Triangles still appear in older exam questions, but they are no longer the correct answer when the question is set in 2026.

V-16 emergency beacon | DGT glossary

Definition

The V-16 is a DGT-approved beacon placed on the roof of the vehicle to signal it has stopped due to breakdown or accident. It is designed to replace warning triangles: the driver does not need to leave the car to deploy it, reducing the risk of being hit on the shoulder or carriageway. From January 1, 2026, the connected V-16 (with DGT 3.0 geolocation) is the only valid pre-signalling system in Spain.

The V signs

The V-16 belongs to Spain's catalogue of vehicle signs — the V series, carried on the vehicle itself to tell other road users something. The ones the approved question bank uses are V-1 (priority-vehicle light), V-2 (amber light on roadworks and service vehicles), V-6 (vehicle or combination over 12 m), V-15 (driver with a disability, allowed into the HOV lane alone), V-16 (pre-signalling of danger), V-20 (panel marking a load that overhangs at the rear), V-25 (the environmental sticker) and V-26 (shared rental vehicles). There is no V-23 or V-27 in any of the 12,154 approved questions: the beacon the rules require is the connected V-16.
