Explanation

This sign warns drivers of a curve in the road ahead. The arrow indicates the direction of the curve, and the text "40 M.P.H." advises drivers of the recommended speed to safely navigate the curve. It is important to follow this advisory speed as the curve may be too sharp to negotiate at higher speeds. Excessive speed can cause loss of control, skidding or rollovers, and may lead to accidents.
