[Closed] Amazing new Dutch cycle facility - *this* is how you deal with a roundabout

The Local Transport Note on cycle facilities says:

The sign to diagram 966 (CYCLISTS DISMOUNT) may be used together with the sign to diagram 965, or on its own. [b]The sign should be provided only where cyclists are required to use a pedestrian crossing facility that they cannot legally cycle on, at the entrance to a pedestrian area, at a location with a low headroom or width restriction (e.g. a subway or bridge) or at places where visibility is restricted to such an extent that cycling would be unsafe [/b]

We have fairly decent guidelines in the UK (albeit with a few glaring issues, like merging with main road traffic at narrow points) but traffic planners are free to ignore them.
