Does a US forklift license expire?

OSHA requires retraining every three years. Therefore, a General Forklift Certification is valid for 3 years. Our program changes the status of a Certified OPERATOR from "Certified" to "Certification Expired" after 3 years. The Training Administrator must then purchase another subscription for General Forklift Training, assign it to that person, then have the person take the training to again become certified. An email notification of this change of status is sent to the Training Administrator 30 days prior to expiration. one year
