You mean right into Clapham Park Road, here: http://maps.google.co.uk/maps?num=100&hl=en&lr=&safe=off&q=bedford+road+sw4&ie=UTF8&hq=&hnear=Bedford+Rd,+London+SW4,+United+Kingdom&gl=uk&ei=LHMGTJbgMuWW4gbe0NXIDA&ved=0CB0Q8gEwAA&ll=51.459943,-0.129175&spn=0.007153,0.019162&t=h&z=16&layer=c&cbll=51.460031,-0.129184&panoid=0G-7f3ESQRbOG3tRhU-dZg&cbp=12,178.19,,0,18.51 This is new and is there not for safety reasons, but to ease congestion as the road is too narrow to allow through traffic to pass on the left (Bedford Rd is notoriously busy, partly because of ill-timed traffic light sequences at this junction). There is just one no left turn sign on the traffic light. Easy to ignore if the light is on green and you've always made that turn before, but the sign is clear, they will argue. There's no come back, I'm afraid. They would rather you turn left and then perform a tricky U-turn to get to where you're going. Bonkers, and dangerous.
