It is unlawful for any person to operate any commercial motor vehicle licensed for more than twelve thousand (12,000) pounds either singly or in combination with a trailer, as both vehicles are defined in Section 301.010, RSMo., 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/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 Chapter 307, RSMo. 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)(12) of this Section, 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. 
Part 395, Title 49, Code of Federal Regulations, relating to the hours of drivers, shall not apply to drivers transporting agricultural commodities or farm supplies for agricultural purposes in this State if such transportation:
1. 
Is limited to an area within a one hundred (100) air mile radius from the source of the commodities or the distribution point for the farm supplies; and
2. 
Is conducted during the planting and harvesting season within this State, as defined by the Department of Public Safety by regulation.
F. 
The provisions of Part 395.8, Title 49, Code of Federal Regulations, relating to recording of a driver's duty status, shall not apply to drivers engaged in agricultural operations referred to in Subsection (E) of this Section, if the motor carrier who employs the driver maintains and retains for a period of six (6) months accurate and true records showing:
1. 
The total number of hours the driver is on duty each day; and
2. 
The time at which the driver reports for, and is released from, duty each day.
G. 
Violation of any provision of this Section or any rule promulgated as authorized therein is a misdemeanor.
H. 
No rule or portion of a rule promulgated under the authority of Chapter 307, RSMo., shall become effective unless it has been promulgated pursuant to the provisions of Section 536.024, RSMo.
A.
