In recent years, the California government has taken steps to reduce noise pollution from vehicles. The new regulations aim to reduce disturbances in public and residential areas. However, these may have negative impacts on vehicles and accidents. With noise limits becoming stricter, drivers might get distracted by other vehicle’s modifications.
California’s exhaust noise laws, particularly Assembly Bill 2496, require vehicle owners to fix noise violations immediately. If you are ticketed for excessive noise, you must fix the issue before driving your vehicle again. These regulations may require you to make costly repairs. If you do not understand the laws, you may face unexpected fines, legal issues, and accidents.
As noise regulations become stricter, the risk of distractions from vehicle noise increases. For example, a driver might be distracted by the loud noise of another vehicle’s modified exhaust. Given the risks, if you are involved in a noise-related accident, it is important to be prepared. Hire an attorney from the Oaks Law Firm and consult with them.

What is the “Noisy Vehicles” law?
California Vehicle Code § 27151, also known as the ‘Noisy Vehicles’ Law, was introduced to reduce noise pollution from motor vehicles by regulating exhaust noise levels. The law requires all vehicles operating on the road to be loud only to a limit of 95 decibels. This is the same as a lawn mower’s noise. The law was aimed to maintain peace in the busy urban areas of CA.
The law applies to all vehicles, including passenger cars and light trucks weighing 6,000 pounds or less. Under this law, it is mandatory to have exhaust systems that only produce a sound of up to 95 decibels. If your vehicle makes a louder noise, you have to undergo modifications. Any modifications to the exhaust that increase noise beyond this limit are illegal.
Law enforcement officers use sound level meters to measure noise. If it is found you are louder, you might be ticketed and fined. They conduct these noise checks at traffic stops and patrols as these areas are particularly noisy. Repeat offenders face more severe consequences, such as higher fines or vehicle impoundment.
How does noise impact car accidents?
Noisy vehicles pose a serious threat because they can distract drivers on the road and potentially cause accidents. Studies have shown that even moderate noise levels can impair a driver’s ability to stay focused. This auditory distraction can slow drivers’ reactions. When drivers cannot filter out these distractions, the risk of a collision increases.
The dangers of loud vehicles may extend to pedestrians on the road as well. In busy urban areas or high-traffic zones, the sounds of engines and honking can distract pedestrians from paying attention to the traffic signals and approaching vehicles. This creates a risky environment where both drivers and pedestrians are less focused.
High-traffic areas are linked to high traffic rates, and noise plays a major role in it. Research shows that areas with a higher accident rate tend to have vehicles with loud noises. The noise does not only act as a nuisance but reduces attention and increases stress levels.
Thus, by implementing the Noisy Vehicles law, California can become a safer place with fewer road accidents.
Arguments against the effectiveness of the law
There have been arguments about the effectiveness of the “Noisy Vehicles” law, especially from car enthusiasts. People have questioned the direct link between noise and safety. Critics of the law have shown scepticism about whether the “Noisy Vehicles” law will be effective in reducing road accidents.
A 2011 study found little correlation between noise levels and an increase in vehicle-pedestrian crashes. However, it is undeniable that a quiet and peaceful environment can indeed promote better concentration.
