New Traffic Pattern Ahead
Warns that lane configuration, geometry, or traffic control has recently changed; stay alert.
Used after construction, restriping, or geometric changes, this warning tells drivers that the road ahead no longer behaves the way it used to. Lanes may shift, turn movements may have changed, or new signals may be in place, so reduce speed, follow lane markings closely, and watch for unexpected movements by other drivers.
