difficulty in negotiating the corner or bend without slowing down. Sign W 051 should be used where the inside radius of the bend is greater than 20m but requires drivers to slow considerably from their approach speed and, in the opinion of the Road Authority, the bend is deceptive and constitutes a potential hazard.
