Do I have to go through refresher training?
Yes. Each qualified collector must go through refresher training every five (5) years in order to remain eligible to collect DOT specimens. [See 40.33(e)] The content of the refresher training must be the same or equivalent to your initial training and proficiency demonstration content. It is expected that you stay current with any changes to the DOT regulations and not wait for the refresher training to learn about them.
