About the same as California. You have a physical inspection under the hood (EGR in tact) and under the truck (catalytic converter). They match VIN numbers on the dash, to the door, to the paperwork. They put the sniffer in your tail pipe and you do 3 "snap" tests. That's where you stomp down on it from an idle up to the rev limit. It measures the amount of soot (opacity) in the air during the snap test. If all are within spec, you pay your $45 and are good for another year.
