Missouri Tractor-Trailer Laws

Tractor-trailer laws in Missouri are there to protect all drivers on the road. To aid in the prevention of Missouri tractor-trailer accidents, truck drivers should familiarize themselves with federal laws and Missouri state laws governing commercial motor vehicle (CMV) operators. Based on our experience as Missouri tractor-trailer accident attorneys at The Hershewe Law Firm, P.C., the following highlights from Missouri’s CMV statutes are particularly relevant and worth noting:

As an out-of-state trucker, you must take all the Missouri commercial written and skills tests to apply for a nonresident Commercial Driver's License (CDL) or permit. For more on this, see Missouri CDL written and skills testing. Be advised that the CDL knowledge written test is only administered in English.
You must have a CDL to operate any vehicle with a gross vehicle weight rating of 26,001 pounds or more, a vehicle designed to transport 16 or more passengers (including the driver), or any size vehicle used to transport hazardous materials.
Federal regulations through the Department of Homeland Security require a background check and fingerprinting for the Hazardous Materials Endorsement.
The act of operating a CMV in Missouri serves as your consent to alcohol testing.
It is illegal to operate a CMV in Missouri if your blood alcohol concentration (BAC) is .04 percent or more.

Under Missouri CMV driver law, you will lose your license for at least one year on your first offense for—

Driving a commercial motor vehicle if your blood alcohol concentration is
.04 percent or higher.
Driving a commercial motor vehicle under the influence of alcohol.
Refusing to undergo blood alcohol testing.
Driving a commercial motor vehicle while under the influence of a
controlled substance.
Leaving the scene of an accident involving a CMV.
Committing a felony involving the use of a CMV.
