Key Regulations for Leaving Your Car Running Unattended in South Carolina

  • State Statute § 56-5-2970: Prohibits leaving a vehicle unattended while running unless the driver is in immediate proximity (e.g., within 10 feet) or uses a remote start system in a private driveway. Violations are classified as a non-criminal offense.
  • Local Ordinances: Municipalities like Columbia and Greenville impose additional restrictions, particularly near high-traffic zones (e.g., schools, hospitals) or during air quality alerts issued by the S.C. Department of Health and Environmental Control (DHEC).
  • 2026 Compliance Shifts: Proposed amendments to § 56-5-2970 aim to expand enforcement to include idling in commercial parking lots, aligning with EPA anti-idling guidelines. Public hearings are scheduled for Q1 2025.

Enforcement typically falls under local law enforcement agencies, with penalties escalating for repeat offenses. Exemptions exist for emergency vehicles or vehicles with active anti-theft systems.
