There's no emissions test in MA after 15 years, just has to pass a safety inspection. Few shops do it right, I believe the proper inspection is supposed to take 45 minutes, most shops will have a sticker on your car in 5-10 minutes. Then I'm sure like the rest of the country, you hear stories of places where you can go for a few extra $$, they'll pass anything.Then it routinely passed (the semi tough I hear) Massachusetts state inspection from '09-'19
