A good cycle path has no driveways crossing it unless there is ample unimpeded visibility between driveway users and the path. In practice, this means that a cycle path must be separated from the boundary (from where driveways emerge) by at least 7 m. Where a cycle path is close to the boundary, cyclists are unable to stop in time to avoid hitting (or being hit by) a car emerging from a driveway.
