No, Missouri law generally prohibits leaving a vehicle unattended with the engine running, as outlined in §304.012 RSMo, to curb theft and carbon monoxide risks. Local ordinances, such as those enforced by the Kansas City Police Department’s Auto Theft Unit, further restrict this practice in high-theft zones. Violations may result in fines up to $200 under municipal codes, though enforcement varies by jurisdiction.
Key Regulations for Leaving Your Car Running Unattended in Missouri
- State Statute §304.012 RSMo: Explicitly deems it unlawful to leave a motor vehicle unattended while the engine is running, with exceptions for remote start systems under §307.377.
- Local Ordinances: Cities like St. Louis and Columbia impose additional penalties, including towing and fines, under municipal codes targeting idling in residential or commercial districts.
- 2026 Compliance Shifts: The Missouri Department of Natural Resources plans stricter enforcement of anti-idling rules in 2026, aligning with EPA guidelines to reduce emissions in urban areas.
Violations are typically classified as infractions, though repeat offenses may escalate to misdemeanors. Remote-start systems must comply with §307.377, requiring the vehicle to be locked and the driver within 50 feet. Law enforcement agencies prioritize enforcement in high-crime neighborhoods where “puffing” (idling to warm engines) is prevalent.
