No, not necessarily. But, you have to train on each “type” of truck. By “type,” OSHA is talking about basic differences — a sit-down rider truck vs. a stand-up truck, or an order-picker vs. a pallet jack. OSHA doesn’t intend that you have to give refresher training because someone starts using the same type of truck made by a different manufacturer. But, keep in mind that the operator will need instruction on any topics, such as the truck’s controls, that are different.
