The D/G licence bends the rules for farm use too, doesn't it? When my buddy started driving, he had his Z endorsement already, but not an A licence. He worked for a greenhouse which was classified as a farm. So he's driving D class trucks with a GZ licence, which was ok thru MTO scales and such. Where they got picky was if the farm leased a truck, like Idealease, then the MTO didn't like him driving it because it wasn't plated for farm use. I can't remember exactly how it panned out?
