What will you do if your vehicle is immobilised on the motorway due to a breakdown during the day?

A)Place 2 hazard pre-warning triangles at 50 metres and visible from 100 metres.
B)Place the hazard pre-warning device at the highest point of the vehicle, ensuring maximum visibility, and switch on the emergency lights.Correct
C)Notify as soon as possible by means of an SOS post.
If the immobilisation is on a motorway or dual carriageway, the emergency light must be used in any case, even during the day, and if it is also due to a breakdown, the hazard pre-warning device must be placed.
The V-16 hazard pre-warning device is an auto-yellow luminous device, type-approved and with geolocation, which operates on autonomous power (battery). It must be placed at the highest point 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 the pre-warning triangles falling out of use.
