A version of SEMA model legislation (H.F. 2452) that would create a vehicle registration classification for street rods and replica vehicles was approved by the Iowa State Legislature and signed into law by Governor Chet Culver. H.F. 2452 defines a street rod as an altered vehicle manufactured before 1949 or a vehicle designed to resemble a vehicle manufactured before 1949. The new law defines a replica vehicle as a reproduction of an originally manufactured vehicle with the substitution or addition of parts to update the vehicle for purposes of safety, performance or reliability. The law allows street rods and replica vehicles to be assigned a registration designation bearing the same model year that the body of the vehicle resembles.
