In 2026, a Spanish-registered bus is immobilised by a breakdown in the right lane of a motorway. Which device must be used to give advance hazard warning?

Correct answer

A certified connected V-16 at the highest possible accessible visible position on the bus.

A certified connected V-16 beacon, placed at the highest possible accessible visible position on the vehicle without exposing yourself to traffic. Since 1 January 2026 it replaces triangles for this bus: do not walk along the motorway to place a triangle 50 metres away. Also use hazard lights if fitted and other required lights. If the roof is unreachable, follow guidance for the highest accessible visible position.
