Correct Answer: B. Within 150 metres of a railway crossing, bridge, tunnel, viaduct, or on a curve/hill crest
U-turns are banned where oncoming drivers cannot see you in time — curves, hill crests — and within 150 m of railway crossings, bridges, tunnels, and viaducts. Freeways prohibit U-turns categorically.
