I was caught in a sudden winter storm northbound on hwy 21 in Ontario at 5 AM, loaded with 45,000 lbs. of ethanol. I couldn’t see any part of the road. The road was white, the sky was white – vertigo was a possibility as was the chance I would slide off the road into a ditch. I was in trouble for 30 miles until I found refuge in Bluewater, Ontario, until the road was passable.
