Answer»

The correct option is (c) Corner SIGHT distance (CSD)

Easy explanation: Bicyclist or pedestrian WAITING at the crossroad MAY SAFELY anticipate the driver of an approaching vehicle. Corner sight provides an adequate time for the waiting user to either cross all lanes of through traffic, cross the near lanes and turn left, or turn right, without requiring through traffic to radically alter their speed.
