Last official word I've heard was that the WaDOL does not accept out of state S/TEP classes for the driving endorsement. This includes my Adventure Sidecar classes.
I have heard from several of my former students that they have taken the card from my class to the DOL and been given their endorsement. That's great and I think it should work that way, but I wouldn't count on it.
If you sucessfully complete my class you should have no problem passing the Wa DOL test, but the official word as far as I know is you are required to take that test. YMMV and if your local DOL office accepts the card, great, but I don't make you any promises that they will.
