No, leaving your car running unattended is illegal in South Dakota under SDCL § 32-31-1.5, with exceptions for remote-start systems or emergencies. Violations may result in fines up to $100 under municipal ordinances like Rapid City’s 2024 enforcement updates, which align with state traffic safety initiatives targeting idle reduction.
Key Regulations for Leaving Your Car Running Unattended in South Dakota
- State Statute SDCL § 32-31-1.5 prohibits leaving a vehicle unattended while the engine is running, with penalties escalating for repeat offenses.
- Municipal Ordinances (e.g., Sioux Falls Municipal Code § 10-101) impose additional fines, often $50–$100, for violations within city limits.
- Exceptions include remote-start systems with the key fob within 30 feet or situations where the vehicle is locked and the engine is running for less than 5 minutes in extreme temperatures.
Local law enforcement agencies, including the South Dakota Highway Patrol, prioritize enforcement during winter months due to idle reduction campaigns. The 2026 state budget allocates $250,000 for idle-reduction education, signaling stricter future compliance measures. Always verify county-specific rules, as some jurisdictions (e.g., Aberdeen) impose harsher penalties.
