Current law prohibits a person from operating 21 a motor truck, trailer, truck tractor, road tractor, or 22 semitrailer having a gross weight that exceeds the vehicle’s 23 registered gross weight by 5 percent. An exception allows such 24 a vehicle transporting certain loads associated with farming 25 to operate on the public highways so long as the gross weight 26 does not exceed the vehicle’s registered gross weight by 25 27 percent. Loads subject to this exemption include raw farm 28 products, fertilizers, raw dairy products, livestock, live 29 poultry, and eggs. “Raw farm product” is defined by department 30 of transportation (DOT) rule to include a list of commodities, 31 including live poultry and eggs (761 IAC 400.47). Another 32 statutory exemption provides that cracked or ground grain 33 may be considered a raw farm product if it is being directly 34 delivered between farms for purposes of cracking or grinding. 35 -3- LSB 2067SV (2) 91 da/ns 3/ 4
