What is California Vehicle Code CVC 27150?
Operating vehicle without adequate muffler or exhaust system
Common scenarios
- You got a ticket after your muffler fell off while driving. You fixed it the next day and have the repair bill.
- Your muffler has a small hole causing extra noise, but you didn’t know it was a problem until the officer stopped you.
- You drive a vintage car with a special exhaust system, and the officer didn’t recognize it as legal.
Key facts
- Muffler must reduce noise: The law requires your muffler to keep your car’s noise at a normal level. Loud, unusual sounds can get you a ticket.
- Repairs can help your case: If you fix the muffler quickly and show proof, the court may reduce or dismiss the ticket.
- Not all exhausts are illegal: Some cars have special exhaust systems that meet legal standards, even if they sound different.

What is CVC 27150?
This law says your car must have a working muffler or exhaust system. The muffler helps keep your car quiet and controls pollution. If your muffler is missing, broken, or loud, you could get this ticket.
Why does this matter?
A loud or missing muffler can be annoying and harmful. It can bother neighbors and might mean your car is polluting too much. The law wants to keep roads safer and quieter.
What does "adequate muffler" mean?
It means your muffler or exhaust system must:
- Reduce noise to a normal level
- Not let smoke or fumes escape in a bad way
- Be in good working condition (not broken or missing parts)
What happens if you get this ticket?
You might have to pay a fine or fix your muffler and show proof. Sometimes, the court will give you time to repair your car.
What can you do?
- Check your muffler for holes, rust, or loud noises
- Get it fixed at a mechanic if needed
- Keep your repair receipts to show the court
Remember, this ticket is about safety and keeping noise down. Fixing it quickly is the best way to avoid bigger problems.
