Sign W 105, Steep Descent, should normally be used where the down gradient is greater than 10% for a distance of at least 30m. Similarly, Sign W 106, Steep Ascent, should normally be used where the up gradient is greater than 10% for a distance of at least 30m. However, these signs may also be used on hills which do not meet these criteria, where the Road Authority considers that there is a particular need, such as a very long hill or one with a poor collision history.
