Car insurance for 2 days down to the states?

[icepak]

Thinking about going down to Portland from Vancouver for 2 days, do I need to buy any short term car insurance to cover the trip or does my ICBC coverage include going down to the states?

If I need it, how much would it cost me roughly? 2009 civic coupe

Thanks

You have insurance on your car, you don't need extra for driving in the US.
