Iowa Code § 326.27

Operation of a commercial vehicle or vehicles in violation of the requirements of this chapter, the motor vehicle registration laws of this state, or the terms of any agreement negotiated by the department pursuant to this chapter may, after due notice and hearing, be grounds for denial of reciprocal or apportioned registration privileges for the vehicle or vehicles of an owner so operated. An owner denied such reciprocal or apportioned registration privileges shall be subject to payment of full annual Iowa registration fees for any such vehicle operated on Iowa highways. In addition to denial of reciprocal or apportioned registration privileges, it shall be a simple misdemeanor, unless such act is declared under Iowa law to be a felony, for any person to operate under reciprocity or apportioned registration in violation of any requirements of this chapter.
