[R.O. 1992 § 375.250; Ord. No. 439 §§ 1 – 3, 10-23-2003]
A. 
The owner of every motor vehicle as defined in Section 301.010, RSMo., which is required to be registered in this State, except:
1. 
Motor vehicles having less than one hundred fifty thousand (150,000) miles, for the ten-year period following their model year of manufacture, excluding prior salvage vehicles immediately following a rebuilding process and vehicles subject to the provisions of Section 307.380, RSMo.;
2. 
Those motor vehicles which are engaged in interstate commerce and are proportionately registered in this State with the Missouri Highway Reciprocity Commission, although the owner may request that such vehicle be inspected by an official inspection station, and a peace officer may stop and inspect such vehicles to determine whether the mechanical condition is in compliance with the safety regulations established by the United States Department of Transportation; and
3. 
Historic motor vehicles registered pursuant to Section 301.131, RSMo.;
4. 
Vehicles registered in excess of twenty-four thousand (24,000) pounds for a period of less than twelve (12) months; shall submit such vehicles to a biennial inspection of their mechanism and equipment in accordance with the provisions of Sections 307.350 to 307.390, RSMo., and obtain a certificate of inspection and approval and a sticker, seal, or other device from a duly authorized official inspection station. The inspection, except the inspection of school buses which shall be made at the time provided in Section 307.375, RSMo., shall be made at the time prescribed in the rules and regulations issued by the superintendent of the Missouri State Highway Patrol; but the inspection of a vehicle shall not be made more than sixty (60) days prior to the date of application for registration or within sixty (60) days of when a vehicle's registration is transferred; however, if a vehicle was purchased from a motor vehicle dealer and a valid inspection had been made within sixty (60) days of the purchase date, the new owner shall be able to utilize an inspection performed within ninety (90) days prior to the application for registration or transfer. Any vehicle manufactured as an even-numbered model year vehicle shall be inspected and approved pursuant to the safety inspection program established pursuant to Sections 307.350 to 307.390, RSMo., in each even-numbered calendar year and any such vehicle manufactured as an odd-numbered model year vehicle shall be inspected and approved pursuant to Sections 307.350 to 307.390, RSMo., in each odd-numbered year. The certificate of inspection and approval shall be a sticker, seal, or other device or combination thereof, as the superintendent of the Missouri State Highway Patrol prescribes by regulation and shall be displayed upon the motor vehicle or trailer as prescribed by the regulations established by him. The replacement of certificates of inspection and approval which are lost or destroyed shall be made by the superintendent of the Missouri State Highway Patrol under regulations prescribed by him or her.
B. 
For the purpose of obtaining an inspection only, it shall be lawful to operate a vehicle over the most direct route between the owner's usual place of residence and an inspection station of such owner's choice, notwithstanding the fact that the vehicle does not have a current state registration license. It shall also be lawful to operate such a vehicle from an inspection station to another place where repairs may be made and to return the vehicle to the inspection station notwithstanding the absence of a current state registration license.
C. 
No person whose motor vehicle was duly inspected and approved as provided in this Section shall be required to have the same motor vehicle again inspected and approved for the sole reason that such person wishes to obtain a set of any special personalized license plates available pursuant to Section 301.144, RSMo., or a set of any license plates available pursuant to Section 301.142, RSMo., prior to the expiration date of such motor vehicle's current registration.
D. 
Notwithstanding the provisions of Section 307.390, RSMo., violation of this Section shall be deemed an ordinance violation.
[R.O. 1992 § 375.260; Ord. No. 439 §§ 1 – 3, 10-23-2003]
A. 
It is unlawful for any person to operate any commercial motor vehicle as defined in Title 49, Code of Federal Regulations, Part 390.5, either singly or in combination with a trailer, as both vehicles are defined in Title 49, Code of Federal Regulations, Part 390.5, unless such vehicles are equipped and operated as required by Parts 390 through 397, Title 49, Code of Federal Regulations, as such regulations have been and may periodically be amended, whether intrastate transportation or interstate transportation. Members of the Missouri State Highway Patrol are authorized to enter the cargo area of a commercial motor vehicle or trailer to inspect the contents when reasonable grounds exist to cause belief that the vehicle is transporting hazardous materials as defined by Title 49 of the Code of Federal Regulations. The Director of the Department of Public Safety is hereby authorized to further regulate the safety of commercial motor vehicles and trailers as he or she deems necessary to govern and control their operation on the public highways of this State by promulgating and publishing rules and regulations consistent with this Chapter. Any such rules shall, in addition to any other provisions deemed necessary by the Director, require:
1. 
Every commercial motor vehicle and trailer and all parts thereof to be maintained in a safe condition at all times;
2. 
Accidents arising from or in connection with the operation of commercial motor vehicles and trailers to be reported to the Department of Public Safety in such detail and in such manner as the Director may require.
Except for the provisions of Subsection A(1) and (2) of this Subsection, the provisions of this Section shall not apply to any commercial motor vehicle operated in intrastate commerce and licensed for a gross weight of sixty thousand (60,000) pounds or less when used exclusively for the transportation of solid waste or forty-two thousand (42,000) pounds or less when the license plate has been designated for farm use by the letter "F" as authorized by the Revised Statutes of Missouri, unless such vehicle is transporting hazardous materials as defined in Title 49, Code of Federal Regulations.
B. 
Notwithstanding the provisions of Subsection (A) of this Section to the contrary, Part 391, Subpart E, Title 49, Code of Federal Regulations, relating to the physical requirements of drivers shall not be applicable to drivers in intrastate commerce, provided such drivers were licensed by this State as chauffeurs to operate commercial motor vehicles on May 13, 1988. Persons who are otherwise qualified and licensed to operate a commercial motor vehicle in this state may operate such vehicle intrastate at the age of eighteen (18) years or older, except that any person transporting hazardous material must be at least twenty-one (21) years of age.
C. 
Commercial motor vehicles and drivers of such vehicles may be placed out of service if the vehicles are not equipped and operated according to the requirements of this Section. Criteria used for placing vehicles and drivers out of service are the North American Uniform Out-of-Service Criteria adopted by the Commercial Vehicle Safety Alliance and the United States Department of Transportation, as such criteria have been and may periodically be amended.
D. 
Notwithstanding the provisions of Subsection (A) of this Section to the contrary, Part 395, Title 49, Code of Federal Regulations, relating to the hours of drivers, shall not apply to any vehicle owned or operated by any public utility, rural electric cooperative or other public service organization, or to the driver of such vehicle, while providing restoration of essential utility services during emergencies and operating intrastate. For the purposes of this subsection, the term "essential utility services" means electric, gas, water, telephone and sewer services.
E. 
Notwithstanding the provisions of Subsection (A) of this section to the contrary, Parts 390 through 397, Title 49, Code of Federal Regulations, shall not apply to commercial motor vehicles operated in intrastate commerce to transport property, which have a gross vehicle weight rating or gross combination weight rating of twenty-six thousand (26,000) pounds or less. The exception provided by this Subsection shall not apply to:
1. 
Vehicles transporting hazardous materials and which are not covered farm vehicles as provided in Subsection (C);
2. 
Vehicles designed to transport sixteen (16) or more passengers including the driver as defined by Title 49 of the Code of Federal Regulations; or
3. 
Vehicles which are defined as covered farm vehicles pursuant to federal laws and regulations and are transporting hazardous materials that require a placard as required by 49 CFR 100-180.
Nothing in this Subsection shall be construed to prohibit persons designated by the Department of Public Safety from inspecting vehicles defined in this Subsection.
F. 
Violation of any provision of this Section or any rule promulgated as authorized therein is an ordinance violation.
G. 
Any rule or portion of a rule, as that term is defined in Section 536.010, RSMo., that is created under the authority delegated in this Section shall become effective only if it complies with and is subject to all of the provisions of Chapter 536, RSMo., and, if applicable, Section 536.028, RSMo. This Section and Chapter 536, RSMo., are non-severable and if any of the powers vested with the general assembly pursuant to Chapter 536, RSMo., to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2009, shall be invalid and void.

Notwithstanding the above table, two (2) consecutive sets of tandem axles may carry a gross load of thirty-four thousand (34,000) pounds each if the overall distance between the first and last axles of such consecutive sets of tandem axles is thirty-six (36) feet or more.
D. 
Whenever the State highways and transportation commission finds that any State highway bridge in the State is in such a condition that use of such bridge by vehicles of the weights specified in Subsection (C) of this Section will endanger the bridge, or the users of the bridge, the commission may establish maximum weight limits and speed limits for vehicles using such bridge. The governing body of any city or county may grant authority by act or ordinance to the commission to enact the limitations established in this section on those roadways within the purview of such city or county. Notice of the weight limits and speed limits established by the commission shall be given by posting signs at a conspicuous place at each end of any such bridge.
E. 
Nothing in this Section shall be construed as permitting lawful axle loads, tandem axle loads or gross loads in excess of those permitted under the provisions of P.L. 97-424, codified in Title 23 of the United States Code (23 U.S.C. § 101 et seq.), as amended.
F. 
Notwithstanding the weight limitations contained in this Section, any vehicle or combination of vehicles operating on highways other than the interstate highway system may exceed single axle, tandem axle and gross weight limitations in an amount not to exceed two thousand (2,000) pounds. However, total gross weight shall not exceed eighty thousand (80,000) pounds, except as provided in Subsections (I), (J), (L), and (M) of this Section.
G. 
Notwithstanding any provision of this Section to the contrary, the commission shall issue a single-use special permit or, upon request of the owner of the truck or equipment, shall issue an annual permit, for the transporting of any crane or concrete pump truck, or well-drillers' equipment. The commission shall set fees for the issuance of permits and parameters for the transport of cranes pursuant to this Subsection. Notwithstanding the provisions of Section 301.133, RSMo., cranes, concrete pump trucks or well-drillers' equipment may be operated on State-maintained roads and highways at any time on any day.
H. 
Notwithstanding the provision of this Section to the contrary, the maximum gross vehicle limit and axle weight limit for any vehicle or combination of vehicles equipped with an idle reduction technology may be increased by a quantity necessary to compensate for the additional weight of the idle reduction system as provided for in 23 U.S.C. § 127, as amended. In no case shall the additional weight increase allowed by this Subsection be greater than five hundred fifty (550) pounds.
