Driving your purchased vehicle in the US

You need a US dealer plate. Prearrange interim insurance with ICBC. Then it's just a matter of driving it to the border crossing. 3 business days, and appropriate paperwork which you are no doubt familiar with. I've driven from Cal on a dealer plate and also picked up a car off a carhauler in Seattle, that one originated in Florida, but the dealer provided me with a Virginia plate, likely to forestall any tax questions in Florida. The dealer I bought from in Califoria, asked me to draft a letter saying the car was being shipped out of state, to cover himself for not collecting tax. He then provided me with a dealer plate and off I drove.
