_ When approaching from the Okehampton direction (the direction in which the motorcycle was travelling) , there is warning triangle sign advising motorists that they are approaching a 12% decrease in the gradient: There is no warning triangle indicating left hand bend ahead, Conversely, when travelling from the opposite direction (Halwill towards Okehampton) there is a warning triangle indicating a right hand bend ahead and immediately below that there is another warning traffic sign indicating a slippery road: There was no signage warning vehicle users approaching the Halwill direction; the apparent course of the road ahead is denoted by the convergence of hedge lines towards the right. Photographs taken of the road from Halwill towards Okehampton (the direction the motorcycle was travelling) show the crest of the hill but does not indicate that there is left hand bend immediately beyond that crest until the driver or rider arrives at that crest If it was deemed necessary to warn drivers travelling from Halwill towards Okehampton that there is a right hand bend ahead, which can be seen from some distance away in that particular carriageway; it would seem appropriate to consider that drivers travelling from Okehampton towards Halwill should have the benefit of warning triangle sign indicating the left hand bend ahead, particularly where that bend cannot be seen until the hill is crested;
