Strategy Behind the Standard
The two stage turn arrangement enables cyclists to turn right without having to move to the centre of the carriageway. It can be of benefit on a multi-lane approach where the speed and volume of motor traffic makes a conventional right turn manoeuvre difficult for cyclists, even with an advanced stop line.
Provision is made for cyclists to pull in to an area of the carriageway in advance of the stop line and pedestrian crossing (where present) on their left, and to wait there until that junction approach has a green signal. At that point, cyclists make a straight across movement to complete their right turn.

How the Standard Should be Applied
Two stage turns do involve additional delay for cyclists compared to turning right from the centre of the junction in mixed traffic, and are therefore less suitable for junctions with long signal cycles. Inter-green periods should be calculated to take into account cyclists moving off to complete their turn. Cyclists waiting to complete the right turn in advance of the stop line must be able to see a secondary signal on the far side of the junction in order to know when it is safe to proceed.
The waiting area may be indicated by cycle symbols and/or a coloured surfacing patch. The size of the area provided for cyclists to wait to complete the turn should accommodate for the size of the cycle design vehicle and the total number of cyclists that are expected to make the turn at peak times.
