Mississippi does not require smog or emission checks on any vehicle registered within the state. The state does require a general inspection, available at your local tire stores, auto shops, and car dealers for $5.

Mississippi meets all federal guidelines for air quality, so it has not yet made smog and emission checks mandatory for the vehicles of its residents. The Mississippi Department of Environmental Quality (MDEC) monitors nine counties within the state, especially the highly populated areas, to determine the air quality index.

Monitored counties include Adams, Bolivar, DeSoto, Hancock, Harrison, Hinds, Jackson, Lauderdale, Madison, and Warren.

How Can I Help?

Just because Mississippi meets all the federal standards for clean air doesn't mean that will always be the case. We should all do our part to protect the environment and cut pollution. Here's a list of helpful things to do:

• Drive less, especially in heavy traffic and on hot days. Carpool, telecommute, use public transportation, ride a bike, or walk; these will all help reduce the amount of harmful emissions released into the atmosphere.

• Save lawn maintenance for cooler days.

• Shop by phone, Internet, or mail.

• Reuse and recycle paper, glass, cardboard, and aluminum when you can.

• Turn off the lights when you leave a room.

• Drive responsibly: Maintain the speed limit, don't idle for too long or rev your motor, and avoid long drive-through lines.
