As the song says, "Oooooooooooo-ok-la-ho-ma, where the winds come sweeping down the plains ... " And sweep they do!

And because of, or maybe in spite of, these sweeping winds, the air quality in Oklahoma still remains excellent. The presence of traffic, oil fields, industry, and other sources of chemical emissions have, so far, not compromised the quality of the air in Oklahoma.

Emissions Controls

Because of that good air quality, Oklahoma is one of the few remaining states that does not require emissions checks for motor vehicles―any motor vehicles, including new, used, custom-made, antique, restoration, or just plain old.

If you need to register a vehicle in Oklahoma, you do not need to get a smog check, regardless of the age of the vehicle.

Restoration Paradise

That's good news for antique and older car lovers. You may bring any vehicle you choose into Oklahoma, unlike other states (California is one) that do not permit people to bring older cars into the state. That's not the case in Oklahoma, at least for the time being. So, if you want to bring a restoration project car with you to Oklahoma, as long as you have your registration paperwork in order, Oklahoma will permit you to do so.

Never Say Never

Oklahoma, being every bit as concerned about the environment and air quality as any other state, keeps a close eye on the sky. If emissions begin to make an appreciable dent in the air quality, expect to see the introduction of emissions controls for factories, refineries, farms, cotton gins, automobiles, and any other potentially polluters.

Annual Inspections

There are no annual vehicle emissions or safety inspections in Oklahoma, although, according to one official at the Oklahoma Tax Commission, mandatory automotive safety inspections are not too far away.

In the meantime, enjoy the freedom from mandatory emissions and safety inspections.
