Dust storms can happen at any-time in the state, but the Arizona Department of Transportation says this first-of-its-kind technology will hopefully help save lives.

“We are ready for the 2021 monsoon season,” said Garin Groff.

Groff, with the Arizona Department of Transportation, says drivers will surely see that once they pass a 10-mile section on I-10 between Picacho and Eloy.

“It is an automated system that can detect when dust starts to reduce visibility,” he told KGUN 9.

“They use beams of light to detect dust particles in the air. Once that happens, the system will automatically activate variable speed limit signs and reduce the regular posted speed limit of 75 to as low as 35,” he added.
