Fog made driving slow across much of South Dakota on Monday. Drivers had to watch their speed with low visibility and some slippery spots on the highways.
There was virtually no visibility at times on Interstate 29 in northern Minnehaha County. Vehicles that could be seen one second would simply disappear into the dense fog that blanketed the area.
"Sioux Falls to Brookings it's really foggy," driver Elizabeth Powell said.
Powell drove from Chamberlain to Brookings on Monday and said she had trouble seeing other vehicles.
"Just watch for other cars because a lot of cars didn't have their lights on so you had to watch for the cars that didn't have their lights on," Powell said.
"Some of the traffic was doing about 40 miles per hour and it was almost too foggy to pass so it's pretty slow traffic," Brookings commuter Wade Jaacks said.
Interstate 29 wasn’t too slippery during the day on Monday. Drivers who were on the Interstate say the fog is the main reason people were taking it easy on the accelerator.
"It's not the normal driving that I normally see coming to and from Brookings, so people are definitely taking winter precautions," Powell said.
But other travelers say the weather was pretty typical for a South Dakota January day and if drivers are cautious they'll get to their final destination despite the dense fog.
"I've seen it before so just drive careful and usually there's no problems," traveler Jordan VonEye said.
And that's exactly what many on the roads did.
"I knew I had time so if I had to slow down I could," Powell said.
And with winter weather expected to hit Monday night into Tuesday drivers might want to think about taking it slow on the roads for a little while longer to stay safe.
