Is Leaving Your Car Running Unattended Legal in Vermont After the 2026 Law Changes?

No. Vermont law prohibits leaving a vehicle unattended with its engine running, except under narrowly defined exceptions. The Vermont Department of Motor Vehicles (DMV) enforces 23 V.S.A. § 1128, which criminalizes idling to reduce air pollution and prevent theft risks. Violations carry fines up to $100, with stricter penalties in municipalities like Burlington, where local ordinances impose additional restrictions. Enforcement has intensified ahead of the 2026 statewide emissions compliance deadlines.

Key Regulations for Leaving Your Car Running Unattended in Vermont

  • 23 V.S.A. § 1128: Prohibits idling for more than five consecutive minutes unless the vehicle is in motion or actively warming in extreme cold (below 20°F for diesel, 10°F for gasoline). Exceptions include emergency vehicles or traffic conditions requiring idling.
  • Local Ordinances: Cities like Burlington and Montpelier enforce stricter limits (e.g., Burlington’s 2023 ordinance reduces the allowable idling window to three minutes). Violations may result in municipal fines up to $250.
  • Commercial Fleet Rules: Businesses operating vehicles over 8,500 lbs must comply with Vermont’s 2024 Idle Reduction Program, mandating engine shutdown after five minutes unless exempt (e.g., refrigeration units). Non-compliance triggers DMV audits and potential fleet registration suspensions.
