High Intensity and Diamond Grade Meet DOT and MUTCD State and Federal Guidelines
MUTCD Information: The GUSTY WINDS AREA (W8-21) sign may be used to warn road users that wind gusts frequently occur along a section of highway that are strong enough to impact the stability of trucks, recreational vehicles, and other vehicles with high centers of gravity. A NEXT XX MILES (W7-3a) supplemental plaque may be mounted below the W8-21 sign to inform road users of the length of roadway that frequently experiences strong wind gusts.
