No, leaving a car running unattended is illegal nationwide under Mexico’s Ley General de Movilidad y Seguridad Vial (LGMSV), with penalties ranging from fines to vehicle impoundment. Local ordinances in Mexico City and Monterrey further restrict idling in high-risk zones, enforced by Secretaría de Movilidad (SEMOVI) and Secretaría de Seguridad Pública, respectively. Violations escalate under the 2026 LGMSV amendments, which mandate anti-idling tech in new vehicles.
Key Regulations for Leaving Your Car Running Unattended in Mexico
- Federal Ban (LGMSV Art. 45): Prohibits leaving vehicles unattended while running, citing fuel waste and theft risks. Violators face fines up to 5,000 UDI (≈$3,500 MXN) or 30-day impoundment.
- Local Restrictions in Mexico City: SEMOVI enforces Reglamento de Tránsito (Art. 7.12), banning idling in residential areas and near schools. Repeat offenses trigger vehicle immobilization.
- State-Level Variations: Monterrey’s Reglamento de Tránsito Municipal (Art. 124) imposes stricter penalties, including mandatory driver education courses for first-time offenders.
