Фото скоростных проездов.И шлагбаумов там.No need to stopWhen a vehicle installed with a Via-T goes through the lane, it is detected by an antenna which makes a little Bip sound and _opens the barrier_ to allow it through.The maximum speed at which you are able to go through the barrier is 30 km/hour. Go any faster and _the barrier_ will not have time to open.
