Grand Junction drivers should be aware that Colorado’s anti‑idling statute, often called the “puffer law,” prohibits leaving a vehicle running and unattended for more than five minutes within a sixty‑minute period. The law, codified at Colorado Revised Statute 42‑4‑1206, is intended to curb vehicle theft and reduce unnecessary emissions.

How the law works

If an officer observes a car idling unattended for longer than the five‑minute limit, the driver can be cited. The standard fine starts at $50 and can increase if the violation continues. Many residents report seeing cars running in neighborhood driveways early in the morning, and the law gives law‑enforcement a clear tool to address the practice.

Legal ways to warm up your car

Colorado’s cold winters make a warm vehicle a comfort, but the law does allow for remote‑start systems. These systems start the engine while the vehicle remains locked, keeping it within the legal definition of unattended. Remote‑start technology is increasingly offered as a factory option in 2025 models and can be added aftermarket for a fee.

Exceptions and private property

The statute primarily applies to public roadways and streets. If a vehicle is parked on a private driveway, the enforcement may differ, though local ordinances can still apply. Drivers should check with their municipality for any additional rules.

Why the law matters to families

Beyond theft prevention, the anti‑idling rule supports cleaner air for families and aligns with community values of responsibility and stewardship. Parents can teach children the importance of respecting the law while still staying warm using remote‑start technology.
