A calculated guess (but a guess, nevertheless) is that it is turning from Birchfield Rd into Asylum Rd (or one of the side roads in the same area) en route for Summer Lane and its normal route into town. Judging by the cars parked behind it (Vauxhall Victor, Hillman Minx, Austin A40 Farina, and a Mini) the date must be early 60s, when much clearance and road alteration was happening in that area. The normal route from six ways was via Alma St to Summer Lane, the former now totally gone.
