No U-turns for vehicular traffic

No U-turns for vehicular traffic sign

What it means

You MUST NOT turn round to face the other way here. It is common on dual carriageways, one-way systems and busy high streets, where a U-turn would block everyone behind you. If you have missed your turning, keep going and use the next roundabout or side road to turn round safely.
