Be sure to remind your customers who are picking up nurse tanks that implements of husbandry ARE NOT ALLOWED on interstate highways. We know the trailers underneath the dual nurse tanks trail easily, although they are not designed for highway speeds, and Illinois law prohibits implements of husbandry on interstate highways. Ammonia nurse tanks are implements of husbandry that require a slow-moving vehicle (SMV) emblem and can be pulled at speeds no greater than 25 mph. IFCA also discourages taking nurse tanks through heavily populated areas, so even if a road through a large town might be the shortest distance between farms, please find a safer and less populous route.  Be safe and not sorry. If you have any questions about ammonia safety or compliance with the ammonia rules, please call John Rebholz at the IFCA office.
