The Reverse Turn (W1-3L or W1-3R) sign shall be used when the tangent distance is more than 600' and the speed limit is 30 MPH or less. Place the Left Reverse Turn (W1-3L) sign in the Sign 1 and Sign 4 locations, and the Right Reverse Turn (W1-3R) sign in the Sign 2 and Sign 3 locations.

The Reverse Curve (W1-4L or W1-4R) sign shall be used when the tangent distance is more than 600' and the speed limit is greater than 30 MPH. Place the Left Reverse Curve (W1-4L) sign in the Sign 1 and Sign 4 locations, and the Right Reverse Curve (W1-4R) sign in the Sign 2 and Sign 3 locations.

The Single Lane Double Reverse Curve (W24-1L or W24-1R) sign shall be used when the tangent distance is less than 600'. Place the Left Single Lane Double Reverse Curve (W24-1L) sign in the Sign 1 location and the Right Single Lane Double Reverse Curve (W24-1R) sign in the Sign 2 location. Sign 3 and Sign 4 are not required for this scenario.
