New motor vehicles which have not been previously titled and registered prior to the initial motor vehicle registration or the next succeeding registration which is required by law;
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., shall submit such vehicles to an annual 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 annual registration or within sixty (60) days of when a vehicle's registration is transferred. 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/her. 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/her.

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.
