I believe someone on here said that Missouri had no emission laws on pre-198x cars, since mine's a 76 model I know I'd be exempt, but I'd like to see whatever gov website has that information. I did a quick google search but it just came up with a bunch of new emission laws for St. Louis.

 

All states have emissions laws that are set on a federal level (EPA). Each state has a choice in how it enforces the federal law. In rural areas there may be no inspections at all. The EPA measures pollution levels in cities and if they are too high they are labeled a "non-attainment area". Once a city has that label they must implement emissions testing or the state looses federal highway funding.

 

From the Missouri DOR website:

Safety and Emissions Inspections
Safety Inspections: Missouri law requires all motor vehicles to pass a vehicle safety inspection performed by an authorized inspection station, unless exempt.

Emissions Inspections: If the vehicle is registered to operate in St. Louis City, St. Louis County, St. Charles County, Franklin County, or Jefferson County, the vehicle is also subject to an emissions inspection. (See below for exemptions from the emissions inspection requirement.)

The inspection station will issue a Certificate of Inspection and Approval that must be presented to an office of the Department of Revenue when the motor vehicle is registered. Vehicle safety and emissions inspections should not be made more than 60 days prior to the date the owner submits an application for title and license or registration renewal.

Thanks but I remember someone on here saying vehicles older than 1980something were exempt from the law, and I am wanting to know where that info came from just to be sure.

Edit: Thanks Tony you posted that as I was posting my message.

 

That's what's nice about Lincoln County. Nothing to worry about.
