Bent-out cycle lane crossings are designed to provide a gap of one or two car lengths between the main carriageway and crossing. This provides an area where a vehicle can store when they turn off the main carriageway; creating safer turning movements and increasing the likelihood of vehicles giving way to approaching cyclists. It also provides an area for vehicles exiting the side road to store without blocking the crossing. An added benefit is that the chicane can slightly slow cyclists on the approach to the conflict point which improves sight distance and heightens the alertness of the cyclists.
