Pennsylvania House Bill 1502: Stop Loud and Excessive Exhaust Pollution (SLEEP) Act
Anyone who lives in Pennsylvania has likely heard it: the roar of dirt bikes, revving engines, or ATVs echoing through the streets late at night or early in the morning. This constant noise makes it hard for families to relax in their homes, enjoy their outdoor spaces, or even get a good night’s sleep.
Excessively loud vehicles don’t just disrupt our peace and quiet—they can also lower property values, increase air pollution, and burden local police with rising noise complaints and enforcement costs.
To address this issue, new legislation was introduced in 2025 called the Stop Loud and Excessive Exhaust Pollution (SLEEP) Act. This bill will:
- Ban the sale of aftermarket exhaust and muffler systems that make vehicles -- including cars, motorcycles, and ATVs -- louder than permitted by law
- Apply to vehicles made after 1978, whether the modified equipment was installed in Pennsylvania or another state
- Set modern noise testing standards using updated decibel limits and distance-based sound measurements
- Require law enforcement training on how to measure vehicle noise accurately and enforce the law
- Ensure vehicles with illegal exhaust systems fail inspection
- Require PennDOT to hold official vehicle inspection stations accountable if they repeatedly allow non-compliant vehicles to pass
- Impose penalties of up to $1,000 in fines, 30 days in jail, or both for violations
This bill was introduced in effort of restoring peace in our communities, giving law enforcement the tools they need to enforce the law, and making sure our streets are safer and quieter for everyone.
