The warning was simple ... if you don't have to go out ... don't.
Icy roads on Saturday caused headaches for drivers, state police and road crews all over the Tri-States.
Rain and freezing temperatures created challenges for drivers in northeast Missouri as well this weekend.
Hannibal MoDOT crews were out early dropping a combination of sand and salt to the main roads to make sure that drivers could travel safely through the area.
Kirk Youngblood is the
maintenance supervisor for the northeast district.
He says that an ice storm is much more challenging to deal with than a snow storm.
"If it was a snow storm basically we'd go out and plow and treat one time and then continue and usually we can get it all pretty quick," Youngblood said. "With this ice it's so hard to figure out what's really going to happen. What these temperatures do."
Using a special gauge, Youngblood is able to monitor the outside temperature and surface temperature on the roads around the area.
Another place where driving was dangerous were secondary roads like this one near Spaulding, Mo.

Trooper Paul Behrens says that a combination of icy conditions and steep grade led to a semi turnover.
"Obviously like the situation we have behind us, there's a lot of black ice and the road does not look slick however when you apply the brakes the vehicle just slides," Trooper Behrens said.
Trooper Behrens says that drivers need to use extra caution on secondary roads.
"The primary focus of MoDOT and
Illinois Department of Transportation
are the primary roads, your numbered roads," Trooper Behrens said. "All your secondary roads always get hit second. So they don't get any attention until the main roads are cleared."
Marion County Emergency Management Director John Hark says that conditions will only get worse.
As the night progresses and this temperature drops, we discourage people getting out on the highways or anything," Hark said. " Get in and stay in until we know that things are safer to come back out.
