No, leaving a car running unattended is illegal under Colorado Revised Statutes § 42-4-1205, with exceptions for remote areas or emergencies. Local ordinances, such as Denver’s municipal code, impose additional penalties, including fines up to $999. Recent 2026 legislative proposals aim to expand enforcement, particularly in high-theft urban zones.
Key Regulations for Leaving Your Car Running Unattended in Colorado
- State Statute Violation: CRS § 42-4-1205 prohibits operating a motor vehicle unattended with the engine running, unless the driver remains within 100 feet or the vehicle is locked and secured in a designated parking area.
- Local Ordinances: Municipalities like Denver, Boulder, and Colorado Springs enforce stricter rules, often requiring immediate ignition shutdown in public spaces or commercial districts.
- Penalties and Enforcement: Violations typically incur Class 2 misdemeanor charges, with fines escalating to $999 in Denver. Law enforcement prioritizes enforcement in high-auto-theft corridors, such as parts of Aurora and Commerce City.
Colorado’s Division of Motor Vehicles (DMV) and local law enforcement agencies collaborate on public awareness campaigns, emphasizing the risks of vehicle theft and carbon monoxide exposure. The 2026 legislative session may introduce mandatory idle-reduction zones in urban cores, further restricting engine operation without active supervision. Drivers should verify municipal codes, as penalties vary by jurisdiction.
