761—607.17 (321) Endorsements. All endorsements except the hazardous material endorsement continue to be valid without retesting or additional fees when renewing or upgrading a license. The endorsements that authorize additional commercial motor vehicle operations with a commercial driver’s license are:
	   607.17(1) Hazardous material. A hazardous material endorsement (H) is required to transport hazardous materials. Upon license renewal, retesting and fee payment are required. Retesting and fee payment are also required when an applicant upgrades an Iowa license or transfers a commercial driver’s license from another state unless the applicant provides evidence of passing the endorsement test within the preceding 24 months. A farmer or a person working for a farmer is not subject to the hazardous material endorsement while operating either a pickup or a special truck within 150 air miles of the farmer’s farm to transport supplies to or from the farm.
	   607.17(2) Passenger vehicle. A passenger vehicle endorsement (P) is required to operate a passenger vehicle as defined in rule 761—607.3(321).
	   607.17(3) Tank vehicle. A tank vehicle endorsement (N) is required to operate a tank vehicle as defined in Iowa Code section 321.1 as amended by 2015 Iowa Acts, House File 635, section 44. A vehicle transporting a tank, regardless of the tank’s capacity, which does not otherwise meet the definition of a commercial motor vehicle in Iowa Code section 321.1 is not a tank vehicle.
	   607.17(4) Double/triple trailer. A double/triple trailer endorsement (T) is required to operate a commercial motor vehicle with two or more towed trailers when the combination of vehicles meets the criteria for a Class A commercial motor vehicle. Operation of a triple trailer combination vehicle is not permitted in Iowa.
	   607.17(5) Hazardous material and tank. A combined endorsement (X) authorizes both hazardous material and tank vehicle operations.
	   607.17(6) School bus. After September 30, 2005, a school bus endorsement (S) is required to operate a school bus as defined in rule 761—607.3(321). An applicant for a school bus endorsement must also qualify for a passenger vehicle endorsement.
	   607.17(7) Exceptions for towing operations.
	      a.    	 A driver who tows a vehicle in an emergency “first move” from the site of a vehicle malfunction or accident on a highway to the nearest appropriate repair facility is not required to have the endorsement(s) applicable to the towed vehicle. In any subsequent move, a driver who tows a vehicle from one repair or disposal facility to another is required to have the endorsement(s) applicable to the towed vehicle with one exception: A tow truck driver is not required to have a passenger endorsement to tow a passenger vehicle.
	      b.    	 The double/triple trailer endorsement is not required to operate a commercial motor vehicle with two or more towed vehicles that are not trailers.
This rule is intended to implement Iowa Code sections 321.1 as amended by 2015 Iowa Acts, House File 635, section 44, 321.176A, and 321.189.
