A Call to Action

You can help the TNRCC get the word to owners of smoking vehicles. The next time you see a car, truck or bus with dirty smoke coming from its exhaust make that call.

Is Your Call Important?

Yes! Since the program started in 1992, the TNRCC has sent more than 50,000 letters to smoking vehicle owners. More than half of them have repaired their vehicles. Repairs ranged from minor adjustments to major engine repairs.
