When I took it, it was 1/2 day with test. Test was based on what instructor said so easy, I also took motorcycle one too. Check with dmv site, it will give you procedures. Again license has to be activated to actually perform inspections on stations machine.
It was quite a while ago when I got my license. Things have really slowed up. Supposedly the DMV "does not have the resources" to keep up with requirements, applications etc. One of those hurry up and wait deals.
Hey guys I just did all my stuff at the start of the summer for work, the 6-8 weeks its BC they have to get enough people in the area to take the class/ test to make it worth the time, not gonna do it every week for 2 people. Also you have to have at least one year in the automotive repair field to be aloud to take the test. I'm not sure but you might have to be working in a shop that does inspections to even take the test, but don't quote me on that last part.
