The sign flashing will be between 9 a.m. and 1 p.m. only on Tuesday, February 16, 2016.
The Nevada Department of Transportation (NDOT) is testing a new wind warning system through the Valley.
Drivers of high-profile vehicles and passenger vehicles will still be allowed to travel on I-580 and Alternate U.S. 395 between Reno and Carson City during the test.
“We have added additional white roadside signs which flash to notify high-profile vehicle drivers when travel is prohibited through Washoe Valley due to high winds,” said NDOT Engineering Services Manager Janelle Thomas. “We are simply testing to ensure these new warning signs work as they should during an actual wind event. Large overhead freeway signs will be in place notifying drivers that they can still travel through Washoe Valley during the tests.”
