Hedge encroaching on road

Over the years the hedge on the opposite side to the village green has been encroaching onto the road. I have never seen it cut back except with the buses that travel this route. In order not to scratch your vehicle you have to travel over the middle line or stop if a larger vehicle is coming in opposite direction. The buses brush along this hedge with every journey and is the only thing that stops full encroachment. Please can you get this cut back.
