The narrow 'road' has been classified by Devon County Council as a 'public way' rather than an unmetalled road, so while it is probably legal to drive on it, it does not have a surface suitable for ordinary vehicles. There is evidence of a gate part way along. The surface is not suitable for any vehicles except tractors beyond a short section, with very deep pits. I have marked the first section as suitable for off-road vehicles only, and the further section as impassible.
