IFCA has received clear guidance from both the Illinois Secretary of State CDL division and the Illinois State Police enforcement division that a Class A CDL is NOT required to transport ammonia nurse tanks.  Ammonia nurse tanks are implements of husbandry and as such, the weight of the nurse tank is not factored into the CDL weight classification.  Ag retail employees need a Class B CDL with hazmat endorsement no matter what the weight or combination of the nurse tanks (1,000 or 1,450 gallon nurse tanks pulled in singles, in tandem or mounted side-by-side on a single running gear).  Or, a restricted Class B Farm Service CDL is available to ag retail employees on a seasonal basis.  If you have any questions, please contact us.
