Can we use the V-16 hazard pre-warning light to warn of the presence of a broken-down car on the carriageway?

A)No.
B)Only if visibility is insufficient.
C)Yes.Correct
The V-16 hazard pre-warning device is a type-approved, auto-yellow luminous device with geolocation, powered by an autonomous supply (battery or accumulator). It must be placed on the highest part of the immobilised vehicle, ensuring maximum visibility. Currently, the V-16 is the only legal option for signalling an immobilised vehicle or an obstacle on the road, with warning triangles now obsolete.
