Arapahoe County, CO – Drivers across the Denver metro are being warned to change winter habits after authorities say leaving vehicles running and unattended — known as “puffing” — is making cars easy targets for thieves.
According to the Arapahoe County Sheriff’s Office, running a vehicle without a driver present, even for a few minutes, is illegal in Colorado unless the car is started remotely and locked. Deputies say these situations often lead to quick thefts, especially during colder mornings when drivers warm up vehicles before work or school.
Officials stressed that many recent vehicle thefts happen in residential neighborhoods, apartment complexes, and driveways, not just parking lots or commercial areas. Thieves are often watching for exhaust smoke or unlocked doors, allowing them to jump into a running car and drive away in seconds.
The sheriff’s office shared several reminders for drivers:
- Stay with your vehicle if it is running
- Never leave keys or key fobs inside
- Lock your vehicle, even in your own driveway
Colorado law allows remote-start systems only if the vehicle remains locked and cannot be driven without the key or fob present. Violations can result in a ticket, and in many cases, a stolen vehicle.
Vehicle thefts typically spike during colder months across Arapahoe County, surrounding counties, and the Denver metro, as criminals take advantage of warming cars. Law enforcement officials say most of these thefts are preventable with simple precautions.
Residents are encouraged to report suspicious behavior and share safety reminders with family members and neighbors, especially during early morning hours.
