Smog Check in Mississippi
Mississippi Vehicle Safety Inspections
In Mississippi, your vehicle is not required to pass an emissions test or smog check, but it does need to pass an annual safety inspection before you can renew its registration.
The Mississippi Department of Public Safety (DPS) administers the Motor Vehicle Inspection Program to ensure that vehicles remain safe enough to operate on public roadways.
On this page you'll find a basic overview of the Mississippi motor vehicle safety inspection program and which agency to contact for more information.
Mississippi does not currently require vehicles to have a smog or emissions test. However, vehicles are subject to safety inspections by the Department of Public Safety's Motor Vehicle Inspections division.
Before your vehicle registration is about to expire, your local county clerk's office may provide you with information about your safety inspection requirements.
Typically, you'll be able to take your vehicle to a Mississippi Department of Public Safety (DPS) inspection station or an authorized third-party inspection station located throughout the state.
For more information about vehicle safety inspections and inspection locations, please contact your local county tax collector or the Mississippi Department of Public Safety (DPS) by calling one of the following numbers:
- (601) 987-1243.
- (601) 987-1252.
Before your vehicle can be inspected, you may need to provide proof of your current vehicle registration, ownership, and car insurance.
Once the safety inspection is complete and your vehicle has passed, you should be issued a motor vehicle safety inspection certificate and sticker, which you may need to affix to your vehicle.
Mississippi Vehicle Safety Inspection Details
While your Mississippi safety inspection will not test your vehicle's smog and emissions outputs, it will check to insure that your vehicle's basic mechanical and cosmetic components are safe and functioning properly.
The licensed inspection technician will typically inspect:
- The body, fenders, and bumpers of your vehicle.
- The vehicle's windshields, mirrors, lights, and reflectors.
- Your vehicle's steering controls and brakes.
- Your vehicle's wheels and tires.
Your safety inspection technician may also need to visually verify your vehicle's vehicle identification number (VIN) to check that it matches your car insurance and registration certificate.
If you pass the safety inspection, you should receive a safety inspection certificate and you should be able to renew your registration with your local county clerk without any issues.
If you fail the safety inspection, you may be provided instructions on what you need to do to repair the issue and take the test again.
If your vehicle fails the test, you may want to contact the Mississippi Department of Public Safety (DPS) Motor Vehicle Inspections Program before you agree to paying for any repairs. There may be extensions, waivers, and exemptions available to you that will allow you to renew your vehicle registration before you are able to repair the issue.
