what to do when faced by particular traffic signs (e.g. turning signs) or road markings (e.g. traffic lane arrows)

There are systematic ways of using the lane arrow marks and approach dots to make it easier to line up a shot, increasing consistency of hitting the pins at the correct location every time.

Behavioral studies have shown that streets with shared lane arrows have increases separation between motor vehicles and bicyclists, encourage cyclists to ride outside the door zone, may reduce wrong-way cycling, and sidewalk cycling, which is associated with increased crash risk, is reduced.
