"It's crazy weather out here like ice rain everywhere. Ice and fog combined, it's just hazardous conditions," said driver, Nonoa Aiono.
Fog is disrupting drivers from Cache County to Sevier County with the thickest layers resting in valleys. It blew through Arizona as a tropical storm and now hovers low over the Beehive State.
"I've almost been in a crash nearly three times," said Aiono.
Drivers often unconsciously speed up in foggy conditions, according to a study conducted by Delft University of Technology in the Netherlands. The school study concludes drivers speed up because they can't see what's ahead providing a false sense of security.
The story across Utah includes ice. Nonoa says he hit a patch in a low visibility area. "I slid into the sidewalk nearly hitting another person," said Ainon.
The fog will remain on the roads through Saturday night and into Sunday morning. Traphagan says the fog should clear out tomorrow afternoon when a snow storm is forecast to drop across the norther regions of Utah.
