It doesn't matter entering the U.S. either. On any given day, at any given U.S. port of entry with any given agent manning the booth, in an empty U.S. plated cargo van the car lane may be the correct lane or the truck lane may be the correct lane. I've been yelled at both and warned to never let it happen again. At the truck booth they may charge you the entrance fee or they may let you slide. In the car lane they may make you park and walk inside to pay or let you go free.Personal use always use car lanes into US, doesn't matter for Canada.
