(2) If a person applies for a renewal or transfer of a commercial driver's license or seeks to add an endorsement, or has a hazardous materials endorsement and applies to retain the endorsement, he shall provide the required medical certificate and take the knowledge test for a hazardous materials endorsement again, unless he provides proof that he has taken and passed the hazardous materials knowledge test within the preceding two (2) years.

(3) Every person applying to add an endorsement to his existing commercial driver's license shall complete an application as required by KRS 281A.140, providing updated information and certifications.
