Questions from employers in this region
Michigan Sugar Company processes millions of tons of sugar beets — what CDL testing applies during harvest?
Michigan Sugar's Bay City processing campaign runs fall through winter, requiring hundreds of CDL operators transporting sugar beets from Thumb-area farms. CDL operators hauling sugar beets in commercial motor vehicles over 26,001 lbs are subject to FMCSA Part 382. We coordinate on-site pre-employment surge testing at Bay City and Thumb-area sugar beet receiving stations during the annual processing campaign.
