Read the signs as you approach the various inspection stations. They'll tell you if you need to pull in or stop. If you can't read the signs, slow down so you can see the next one.
If you bypass an inspection you were supposed to stop for, I'm sure you'll find out about it soon. If you have out of state plates, you might be excused for bypassing the inspection station, but might be subjected to a little extra scrutiny.
