Please enter your ZIP Code to access Smog Check and Car Inspection specific to your state:

Growing concern over clean air has spurred state governments to impose vehicle emission checks. Some states require mandatory emissions testing, while others don't require them at all. To keep you legally compliant, DMV.org focuses this section on the smog and emission rules specific to your state.

If your state does require a smog and emission check, DMV.org will provide the exact steps to take on how to be tested.

Not only will you find whether the test is annual or biannual, but also help finding emissions test locations, how much you can expect to be charged, and what to do if your vehicle fails. Plus, if your state provides exemptions for older cars we'll list them, too.

And because many state Motor Vehicle departments test in tandem with state environmental commissions, you'll also find phone numbers and website links to contact, just in case you need some technical advice.

At DMV.org, you'll find everything you need to clear the air on this sometimes confusing issue.
