Double Reverse Curve Left (RUS)

Bone Safety Signs

MUTCD: W24-1aL

The Double Reverse Curve (W24-1, W24-1a, or W24-1b) sign  may be used where the tangent distance between two reverse curves is less than 600 feet, thus making it difficult for a second Reverse Curve (W1-4 series) sign to be placed between the curves. If the design speed of the curves is 30 mph or less, Double Reverse Turn signs should be used.
