These signs indicate that dangerous or unexpected bends in the road are ahead. Signs typically indicate whether the curves are to the right or to the left, the angle of the curve and whether it is one curve or a series of curves.

==== Chevrons and arrows ====

[[Chevron (insignia)|Chevron]]-shaped symbols or arrows on rectangular signs may be placed at the actual location of the bend or curve to further mark the location of the curve and to assist in the negotiation of the curve. They may also be used to indicate "merge" with other traffic, as for an on-ramp of a limited-access [[highway]].

An unusual occurrence of the rectangular arrow sign appears on the eastbound approach to [[Dead Man's Curve#Ohio|Dead Man's Curve]] in [[Cleveland, Ohio]], US, a curve so sharp that in places an arrow's stem is printed on one sign and the arrow's point is printed on another larger sign further down the road; from the driver's perspective at a distance, the two signs visually blend together to form one large arrow image.
