emissions inspection - what does it entail?

They hook your car up to a machine to see if your car passes all IM readiness monitors and doesn't have a check engine light, or if its a non ODBII vehicle, you get a sniffer up the tail pipe. Process doesn't take long. If its before '95 warm up yoyr car 15 minutes before taking your car in.

YEAH

They check to see the levels of car emissions through the tailpipe
