The high-visibility reflective vest must always be put on before leaving the vehicle. Its purpose is to ensure that the driver is visible to other road users from the very first moment they are exposed to traffic on the road or shoulder. For this reason, it is mandatory to keep it in a place accessible from the driver's seat, such as the glove compartment.
