Then emerging from an access, the driver of a car is located about 2m (X in the diagram) back from the nearside carriageway edge and their eye level is about 1m above the surface.
From this point, the driver needs to be able to see as far as possible along the road in both directions.
On through routes, the distances shown in the table should be achieved in either direction, measured along the nearside carriageway edge.
Speed limit (MPH) | Distance (Y |
---|---|
30 | 90 metres |
40 | 120 metres |
50 | 160 metres |
60 | 215 metres |
Where these distances cannot be achieved, the applicant should clear their site frontage of all obstructions over 1m in height (600mm in the case of vegetation) for as far as possible in either direction from the access.
