Hesperia FAQ
Can Hesperia pass a stricter vehicle exhaust law than the state?
Vehicle equipment standards are largely preempted by the California Vehicle Code (Veh. Code 21), so Hesperia cannot lower the 95 dBA cap. Hesperia (via the Sheriff's Station) enforces CVC 27150/27151 locally and uses Chapter 8.32 against persistent stationary vehicle noise.
What happens after a loud-exhaust ticket in Hesperia?
Drivers are typically ordered to a state-certified Bureau of Automotive Repair Referee Center. The Referee verifies the exhaust meets CVC 27150 - often through a 95 dBA SAE test - before the correctable citation can be signed off and dismissed.
