State Vehicle Inspection Rules in Plain English
Vehicle inspection rules differ a lot from state to state: how often, what is tested, what it costs and who needs an emissions test. These guides summarize each state's official rules.

This site is not run by any state DMV, state police or environmental agency, and it is not affiliated with any repair shop or inspection station, including any business with a similar name.

How to prepare for any inspection
- Note the month on your sticker and book early. Check how close to the due date the state lets you inspect.
- Make sure the check engine light is off. A lit light is a common reason for an emissions failure.
- Check every light, the horn, wipers, tires and mirrors yourself first. Cheap fixes are easy to do before the visit.
- Ask the station about its fee and what happens if the vehicle fails. Rules for retests and reinspection windows differ by state.
Frequently asked questions
Where does the information on this site come from?
From the official websites of each state's DMV, state police or environmental agency, and from the state statutes where a fee is set by law. Every page lists its sources. We do not use figures from third-party sites.
Why is my state not listed?
We publish a state only after checking its rules on an official source. Some official sites block automated access, and in some states the rules have recently changed or sources disagree. More states will be added as they are verified.
Is this the official inspection program?
No. This is an independent guide. For official decisions, contact the state agency listed in the sources at the bottom of each page.
