Explanation:
A special vehicle, and the light indicates its position on the road: Correct
The V-2 light signal, which consists of a luminous device with one or more yellow auto-lights, indicates that the vehicle carrying it is a special vehicle. This light indicates the position of the vehicle on the road or in its vicinity.
Special vehicles use this signage when they are performing a service, activity, or work operation, whether stopped, parked, or traveling at a speed not exceeding 40 km/h.
In addition, this V-2 light signal is used by special transport vehicles and their pilot or escort vehicles, as well as by escort vehicles at sporting events, cycling races, and other similar events.
