Commercial Drivers License Information

What is the Commercial Driver's License Law?

New federal standards for testing and licensing heavy truck and bus operators are required by law in Kentucky. These minimum standards will guarantee the fitness of commercial motor vehicle operators by requiring demonstrated ability to drive heavy vehicles before a license is issued.  The CDL laws and standards cover drivers in all 50 states, the District of Columbia, Mexico and Canada. Motor Carriers will be held responsible if their drivers operate a commercial motor vehicle without a valid CDL.

All applicants for a CDL (original and renewal) are required to undergo a "hot file" check conducted by Kentucky State Police. The cost is $3.00 and will be collected by the Circuit Court Clerk's office at the time of issuance. It will be an instantaneous check and will not delay the driver in receiving his/her CDL. If a "hit" occurs, a notice will be sent to the law enforcement agency that originated the warrant for further investigation.
