Smoking Vehicle Program

The Smoking Vehicle Program is a program run by Mecklenburg County Air Quality (MCAQ) in accordance with North Carolina General Statute 20-128.1. This program helps prevent excess pollution in our community. Residents may report vehicles that are observed emitting excessive visible emissions within Mecklenburg County. MCAQ then notifies the owner of the reported vehicle of the resident report. If necessary, the vehicle should be repaired or adjusted so it does not smoke.

Why are smoking vehicles a problem?

Chemicals in the smoke contribute to the larger air quality problem in Mecklenburg County and the surrounding region. This smoke causes irritation of the eyes, nose, throat and lungs, especially for children, older adults and people with chronic lung disease.

When smoke is coming from the tailpipe of a motor vehicle, it indicates some type of mechanical problem. Catching these problems early can prevent expensive repairs down the road. A vehicle that is not properly maintained also costs more to operate due to increased fuel and oil costs.

Help Stop Smoking Cars!

Report smoking vehicles to Mecklenburg County Air Quality (MCAQ) to improve local air quality, help people with respiratory (breathing) problems breathe a little easier, and notify your fellow drivers of potential mechanical problems.

North Carolina General Statute 20-128.1 - "Control of Visible Emissions," prohibits gasoline and diesel powered vehicles from emitting visible smoke for longer than 5 seconds.
