Over the years I have noticed a real quick and decisive way to determine the operators driving skills. No matter what warehouse or customer or application, if the operator drives the equipment right on the verge of outta control, I would automatically know they could be trusted, and I would turn my back on them while making repairs. The ones you need to watch out for are the slow-pokes, very unsure of the controls and travel speeds. In every instance what at first would look like a cautious driver, was in fact the worst operator in the building!!As far as training green horns on equipment goes, I dont believe any of the written is applicable from an operator standpoint. As a tech I know its important for them to know what to do in an emergency or tip-over etc. But theres no substitute for experience and having the "feel" of the equipment. I trained and certified drivers in Texas for 6 years on both stand-ups and counterbalance units, and other than the pre-trip inspection most everything I graded them on was their confidence displayed when operating the truck. After some preliminary driving on the equipment, I would encourage them to not be overly cautious on my account, just drive the truck and be sure of their controls.
