A 2 lane double reverse curb can be dangerous, especially during a weather storm. Install this sign to show drivers the exact layout of the curve. A sign is a public service.
Standard: 01 If a Double Reverse Curve (or Turn) sign is used, the direction of the double reverse curve (or turn) shall be appropriately illustrated. Except as provided in Paragraph 3, the number of lanes illustrated on the sign shall be the same as the number of through lanes available to road users.
