Yes, Wyoming law permits leaving a car running unattended, but local ordinances and safety codes impose critical restrictions. The state lacks a blanket prohibition, yet municipalities like Cheyenne and Jackson enforce anti-idling rules under their municipal codes. Violations may result in fines up to $750 under local air quality ordinances, particularly during ozone action days. Insurance implications and theft liability further complicate compliance.
Key Regulations for Leaving Your Car Running Unattended in Wyoming
- Cheyenne Municipal Code § 8.16.050 prohibits idling for more than 5 minutes within city limits, with exceptions for emergency vehicles and extreme temperatures. Violators face fines escalating from $100 for first offenses.
- Jackson Hole Air Quality Ordinance (2024) bans idling near schools, hospitals, and within 100 feet of residences during high-pollution alerts. Enforcement is managed by the Teton County Health Department.
- Wyoming Statute § 31-5-207 requires drivers to remove keys from unattended vehicles, creating liability for theft or accidents if this standard is violated.
Local enforcement varies; Laramie’s 2026 draft ordinance proposes stricter penalties, including mandatory anti-idling signage near public facilities. Insurance providers may deny claims if a running vehicle is stolen due to negligence. Always verify municipal codes before idling, as non-compliance risks both legal and financial repercussions.
