It's bad for the environment. It's a huge risk. And, it's illegal in the City of Thornton. With colder temperatures on the way, lots of people may be ready to start a familiar routine--starting up their vehicles and letting them warm up before driving them. Known as 'puffers', these unoccupied idling vehicles provide a perfect opportunity for car theives.

The Police Department sees a significant increase in stolen vehicles during the winter--many of the cars taken were already running and warm for the car thief. City residents need to know that it is illegal to leave your vehicles running unattended.

Air pollution is already at its worse during the winter. Just add to that many vehicles just sitting and idling, and you can see how the problem of puffers just compounds our air pollution problem. So get out your gloves and cushions when you get into that cold car. You'll be helping the environment, protecting your car and obeying the law while you warm up your vehicle.
