I’ve driven the full length of I-55.
It can be treacherous all season long. Tornado like rain, snow white outs, dust storms.
You need to pull off immediately when this happens. Not keep driving like most people do.....
Problem is, if you pull off, find a place to get WAY off, or you may get clonked hard from the rear if an accident or near accident develops just behind you. Obviously this an advantage for 4WDS / AWD vehicles with good traction off pavement tires and high ground clearance.
