Not all but I have seen garbage trucks with left and right steering wheels. Seems it's for when only one person on the pickup route and and they drive with the LH side and get out to pick up the trash safely curbside.Yes , it was very different driving your LHD in Canada and USA when I was there in 2001, after 5 weeks I think I was worse pulling out in to oncoming traffic and always looking the wrong way. The people I've asked about driving LHD in Oz all say they like it but I don't believe them.
Our garbage trucks are LHD what about yours?
