CHP Bulletin on Enforcement of Exhaust Noise and Systems



EXCESSIVE NOISE ENFORCEMENT
PASSENGER VEHICLES, LIGHT TRUCKS AND MOTORCYCLES


The California Highway Patrol (CHP), Commercial Vehicle Section (CVS), has received many inquiries about excessive noise emitted by passenger vehicles, light trucks and motorcycles.Enforcement personnel and the public have inquired regarding enforcement of the Vehicle Code (VC) sections pertaining to excessive noise emitted by these vehicles.

Excessive noise is primarily a nuisance issue rather than a safety concern, and determination of excessive noise is subjective. For this reason, enforcement personnel are to exercise sound professional judgment in making a determination of violation. The following guidelines and attached question and answer sheet (Attachment A) provide guidance to enforcement personnel regarding appropriate enforcement procedures.

Enforcement Guidelines

The only drivers who should be cited are those whose vehicles:
  1. are not equipped with a muffler;
  2. clearly emit an offensive, harsh, excessive noise, or;
  3. have a clearly defective exhaust system (holes, leaks, etc.);

Clearing Citations

When clearing excessive noise citations issued by the CHP or allied agencies, personnel are to consider exhaust systems in compliance if they incorporate a reasonably effective muffler do not omit an offensive, harsh, excessive noise, and appear to be in good repair.

-1- AAIB 98-100



--------------------------------------------------------------------------------


ATTACHMENT A






Q1 Doesn't the VC require a muffler on every vehicle?



Yes. Section 27150 requires that every motor vehicle subject to registration be equipped with an adequate muffler- There are no exceptions -- all vehicles must be equipped with a muffler as defined in Section 425 VC. A turbocharger is not considered a muffler.

Q2 Aren't all exhaust system modifications prohibited?



No. Section 27151 VC prohibits the modification of the exhaust system to amplify or increase the noise emitted by the vehicle, making the vehicle not in compliance with Section 27150 VC or exceeding the noise limits established Sections 27201-27206 VC. Sectlon 27151 VC does not prohibit all modifications to an exhaust system. It also does not prohibit all modifications that increase the noise level of the exhaust system over that of the original, factory-installed exhaust system (as it did until 1980). It only prohibits modificatlons that result in a noise level higher than those specified in Sections 27201-27206 VC. Accurately determining compliance with Sections 27201-27206 VC for enforcement purposes is generally impractical. Enforcement personnel must make an informed professional evaluation to determine if excessive noise statutes arc being violated.


Q3 Do I have to actually listen to a vehicle to cite it for a violation of either Section 27150 or 27151?



Yes. Drivers of vehicles should not be cited for violation of either Section 27150 or 27151 VC unless the officer has personally listened to the vehicle in operation. This can be either under actual driving conditions or with the vehicle stationary and the engine running. Even if the officer has inspected the exhaust system and does not see a muffler present, the officer should listen to the vehicle. The purpose of this is to be sure that the exhaust system does not incorporate internally baffled pipes or other components that meet the definition of a muffler. There are no specifications which state required configurations or minimum dimensions for mufflers. A vehicle that does not visually appear to be equipped with a muffler, but does not emit excessive noise, should be deemed to comply with Sections 27150 and 27151 VC.


Q4 Does an aftermarket, replacement or modified tailpipe or muffler tip constitute a violation of Section 27151 VC?


No. Section 27151 VC prohibits the modification of exhaust systems to amplify or increase noise. The officer would have to establish that the modification increased the noise emitted by the vehicle by listening to the exhaust. In general, exhaust system piping, tubing, fittings, cosmetic tips or other passive devices placed behind the muffler have minimal impact on exhaust system sound levels.


Q5 Since Section 27150 requires that the muffler prevent excessive and unusual noise, can the driver of a vehicle be cited for violation of Section 27150 if it emits a sound different than the original factory installed mufffer?



No. The prohibition against unusual noise refers to noises that are unusual for motor vehicles. Noise that may be unusual for a particular make or model of vehicle, but which is not necessarily unusual for other motor vehicles, should not be considered in violation, provided the noise is not excessive.


Q6 Aren't all modified exhaust systems unlawful under pollution control laws?


No. Current pollution control laws regarding aftermarket exhaust systems are quite complex, but do permit the installation of a variety of aftermarket and "exempt" systems. Due to the complexity of modern pollution control systems and the laws governing them, the CHP does not provide technical training in this area. Enforcement of pollution control laws is the responsibility of the Bureau of Automotive Repair through the "Smog Check" program.


Q7 What are the noise levels specified in Sections 27201-27206 VC? Can these be used to cite loud vehicles?



No. Section 27200 VC prohibits the sale of new motor vehicles that exceed the noise limits specified in these Sections. The specified noise limits (80 dB(A) (decibels)) for all new cars, pickup trucks, vans and motorcycles apply only to new motor vehicles, under full throttle acceleration tests, measured 50 feet from the test vehicle, as specified in Sections 1040-1044, 1046 and 1047, Title 13, California Code of Regulations (13 CCR). These noise levels and the specified test methods apply to manufacturers and new car dealers only, for new vehicle certification purposes, and may not be used for enforcement purposes against vehicles being operated on public roadways. The CHP is not aware of any significant violation of Section 27200 VC by vehicle manufacturers or dealers.


Q8 What are the noise levels specified in Sections 23130 and 23130.5 VC and how can they be enforced?


Sections 23130 and 33130.5 VC specify noise standards for vehicles operating on the highway (in-use vehicles), and are intended for use in actual traffic conditions. The limits of Section 23130 apply under all conditions of grade, load, acceleration, and deceleration. The lower limits of Section 23130.5 apply only to relatively level roadways and under conditions of relatively constant speed. They specifically do not apply to areas of congested traffic that require noticeable acceleration or deceleration, or within 200 feet of an official traffic control device or change in grade. Although these sections were intended for use in actual traffic conditions, the complexities of of noise testing require the testing be conducted in a relatively large open area free of other vehicles and large sound-reflecting objects. This makes in-use vehicle noise testing in most developed areas impractical, where noise complaints are most likely to occur. The CHP does not curently provide either the instrumentation or training necessary to conduct vehicle noise testing. Enforcement using Section 27150 or 27151 VC is usually more appropriate and effective.


Q9 What is the exhaust noise test specified in13 CCR? Can this be used for enforcement?



Sections 1030-1036, 13 CCR, were intended to be used by Licensed Muffler Certification Stations as a means of determining if an exhaust system met the requirements of the Muffler Certification Program (when those programs were operational). They specify testing procedures for motor vehicles exhaust noise alone (as opposed to total vehicle noise). This procedure specifies a limit of 95 dB(A) measured 20 inches from the exhaust pipe outlet with the engine operating in neutral, typically at a speed of 3000-5000 rpm. (For comparison, a modern rotary lawn mower with a 5 horsepower Briggs & Stratton engine typically emits approximately 93 dB(A) at the same distance at full speed under no load.) It applies only to passenger vehicles. It does not apply to motorcycles or to vehicles over 6000 pounds gross weight.


Q10 Can this test be used in enforcement?



Not readily. Although much simpler than the test methods specified in Sections 23130 and 23130.5 VC, this test method still requires some technical expertise and a means to determine both the speed (rpm) of the engine under test (tachometer) and the rpm at which maximum horsepower of the engine is developed (information which may not always be readily available), as well as a sound level meter. It is not intended for roadside noise testing. The CHP does not currently provide either the instrumentation or training necessary to conduct exhaust noise testing. This test is useful, however, for determining if an aftermarket or performance exhaust system complies with VC requirements. It should be noted that the 95 dB(A) level, because it is intended as a simple "go-no-go" type of test, may permit exhaust noise somewhat higher than those permitted under Sections 27201 27206 VC. An exhaust system that complies with the requirements of Section 1036(d)(1), 13 CCR, is deemed to comply with Sections 27150 and 27151 VC.


Q11 What happened to the Muffler Certification and the Licensed Muffler Certification Station Programs?


Funding for both programs was terminated in 1979. There are currently no Official Muffler Certification Stations, no listing of certified mufflers, and no formal mechanism in place to conduct objective vehicle or exhaust noise testing.


Q12 Can local authorities enact or enforce more strict ordinances regarding vehicle noise?



No. Section 21 VC makes the VC applicable and uniform throughout the state, and prohibits local authorities from enacting or enforcing any ordinance on the matters covered by the VC unless expressly authorized to do so. In-use vehicle noise is addressed in Sections 23130 and 23130.5 VC. There is no provision in the VC that permits local authorities to adopt additional noise limitations. Consequently, citations issued under such ordinances are invalid.


Q13 Some aftermarket exhaust systems include documentation that the system has been tested and found to meet the requirements of Section 1036(d)(l), 13 CCR. Are those legal?



The CHP does not have the resources to independently verify manufacturer's claims, but is aware that some aftermarket exhaust systems do meet the noise levels specified in Section 1036(d)(l), 13 CCR. An officer may consider such documentation in evaluating an exhaust system for excessive noise, both during the issuance of a citation and when clearing a citation pursuant to Section 40610(b)VC.


Q14 What type of enforcement action should be taken against vehicles emitting excessive noise?


Providing none of the disqualifying conditions listed in Section 40610(b) are present, the use of the CHP 281, "Notice to Correct," or checking the Dismissable Violation "Yes" box on the CHP 215, "Notice to Appear (Arrest Citation)," would be appropriate for these violations.

Info on "Correctable" vs "Non-Correctable" equipment violations.
http://www.bikersrights.com/states/c...a/CJCKnox.html


OVERVIEW:
Helmet tickets and most recently exhaust systems and tinted windows tickets have been changed to "Non-Correctable" equipment violations by the California Judicial Council (CJC) through misuse of the "Bail and Pentalies Schedule."

The CJC is authorized by the California Constitution, Article VI § 6 to make review and some changes, but with VERY definite limitations [excerpt] :

"... the [Judicial] council shall survey judicial business and make recommendations to the courts, make recommendations annually to the Governor and Legislature, adopt rules for court administration, practice and procedure, not inconsistent with statute..."


Changing a law from a correctable equipment violation to non-correctable one is inconsistent with the law. The CJC has overstepped its authority before and were sued and lost in Superior Court. In California Court Reporters Assn vs. CJC (39 Cal.App.4th 15 - 1994), Alameda Superior Court Judge Reardon, states:

"The Judicial Council argues that as it and the Legislature both derive their powers from the state Constitution, the two institutions are coequals. We find this argument to be specious."

Specious - A specious argument is not simply a false argument, but one that has the ring of truth.

By overstepping their authority, the CJC is violating the Separation of Powers between the Judicial and Exectutive Branches and worse, changing laws without the representative knowledge of the Legislature and People.

Below is the beginning of correspondence with the California Legislature. Posting of the CJC's reply will follow as soon as it's received...



Tuesday, August 22, 2000

Assembly Member Wally Knox
State Capitol Room 6025
Sacramento, CA 95814

Dear ,

Please find attached my ticket for an alleged 27151 violation checked as correctable by the CHP, the L.A. Valley Court non-correctable bail notice I received , a Fullerton Court correctable Bail Notice for a similar exhaust violation per your request.

When I read that my bail was $77 without mention of correctability, I called the LA Valley Court Clerk who advised me very definitely that 27151 was no longer correctable per the 2000 Bail Schedule. I have seen a copy of the 2000 Bail Schedule and see that 27151 is listed as non-correctable, but according to the law, it is definitely correctable.

Contrary to Mr. Tucker of the California Judicial Council's interpretation of VC 40303.5 sub-section (d), my read of it only serves to prove that 27151 is clearly a correctable violation. Regardless of his or the CJC's opinion or "feelings" about this or any law, the CJC cannot modify any law inconsistent with it's spirit or Legislative intent. To do so is beyond the Judicial Branch's Constitutional power and authority.

40303.5. Whenever any person is arrested for any of the following offenses, the arresting officer shall permit the arrested person to execute a notice containing a promise to correct the violation in accordance with the provisions of Section 40610 unless the arresting officer finds that any of the disqualifying conditions specified in subdivision (b) of Section 40610 exist:

Any registration infraction set forth in Division 3 (commencing with Section 4000).
Any driver's license infraction set forth in Division 6 (commencing with Section 12500), and subdivision (a) of Section 12951, relating to possession of driver's license.
Section 21201, relating to bicycle equipment.
Any infraction involving equipment set forth in Division 12 (commencing with Section 24000), Division 13 (commencing with Section 29000), Division 14.8 (commencing with Section 34500), Division 16 (commencing with Section 36000), Division 16.5 (commencing with Section 38000), and Division 16.7 (commencing with Section 39000).
In the opening the language "shall" means "must" unless the person is disqualified per 40610.b.

These disqualifying conditions are threefold:

Evidence of fraud or persistent neglect.
The violation presents an immediate safety hazard.
The violator does not agree to, or cannot, promptly correct the violation.
In the absence of any of the disqualifying conditions, the officer "shall" permit the arrested person to execute a notice containing a promise to correct the violation, which CHP Officer Riley did per the law.

In 40303.5 subsection "d", the Code also states:

(d) Any infraction involving equipment in Division 12 (commencing with Section 24000)
Division 12 ranges from 24000 to 28150. My ticket, 27151, is for an alleged exhaust system violation, which is certainly a piece of equipment, and the statute number falls well within Division 12. I see absolutely no confusion in the language. It is very clear. 27151 is equipment always has been part of Division 12 and clearly a correctable violation.

After being on the books for over 30 years, it seems strange indeed that the CJC would suddenly need to interpret what they feel the Legislators "really meant" in a few fairly innocuous equipment laws. If the Legislature didn't want 27151 to be correctable, I'm certain they would have written it that way or amended it over the subsequent 30 odd years.

In addition to changing 27151, the CJC also changed VC 27803 (the helmet law) from correctable to non-correctable a few years ago. And just like 27151, VC 27803 is listed as equipment and part of Division 12 and was intended to be correctable.

California Judicial Council

In addition to what the Vehicle Code says, I have done some research on the CJC and it's authority regarding existing statutes. Per the California Consitution (Article VI. §6), the CJC does have the authority to review the Bail Schedule, but as I understand it, any revision must be in harmony ("not inconsistent") with the law and Legislative Intent.

California Constitution, Article VI, § 6 - Judicial Council

To improve the administration of justice the council shall survey judicial business and make recommendations to the courts, make recommendations annually to the Governor and Legislature, adopt rules for court administration, practice and procedure, not inconsistent with statute, and perform other functions prescribed by statute.

"not inconsistent with statute" is part and parcel of the CJC's authority and their limitations. In California Court Reporters Association vs. California Judicial Council (39 Cal.App.4th 15 - 1994), Alameda Superior Court Judge Reardon, defines "not inconsistent" to mean:

Construing the relevant constitutional language, the trial court defined the term "not inconsistent" as "not ... merely inharmonious or unsymmetrical, but connot[ing] impossibility of concurrent operative effect, or contradictory in the sense that the provisions cannot co-exist .... ["] " 'Inconsistent' means mutually repugnant or contradictory; contrary, the one to the other, so that both cannot stand.

Correctable and non-correctable are clearly contradictory states and cannot co-exist which clearly illustrates that making 27151 and 27803 "non-correctable" would be totally inconsistent with the existing law and quite beyond the CJC's authority.

Further, the Superior Court addresses the extent of the CJC's authority to make rules. Take particular note of the second and third sentences. It appears that the CJC has attempted to test its boundaries before:

II. A. [4] Preliminarily, we must determine the relative value to be assigned to the Judicial Council's rules and the Legislature's enactment of statutes before we turn to the merits of our inquiry. The Judicial Council argues that as it and the Legislature both derive their powers from the state Constitution, the two institutions are coequals. We find this argument to be specious. The Constitution reserves to the Legislature and the people of this state the higher right to provide rules of procedure. The Judicial Council's right is secondary-a right to adopt rules only when the higher authority of the Legislature and the people has not been exercised. (Stockton Theatres, Inc. v. Palermo (1956) 47 Cal.2d 469, 476-477 [304 P.2d 7]

Reviewing the Bail Schedule is one thing. Changing a correctable violation to non-correctable is a major contradictory revision that must go through an accountable representative Legislative process, rather than an internal private Judicial process; hidden from the Legislature's and People's view in violation of the California Constitution and case law.

I would like the CJC to send us a copy of the 1999 and 2000 Bail and Penalty Schedule for side by side comparison. It should further support that 27151 was not always "non-correctable" as Mr. Tucker of the CJC would have us believe.

Given the above, I think we need to ask on what authority did the CJC change both VC 27151 and VC 27803 from correctable equipment violations to non-correctable ones. Further, if the CJC will not back down, I would like an opinion Attorney General Lockyer. Having served in the Legislature, I would bet he could shed the proper and binding light on all this.

Thank you very much for your concern and help.

Sincerely,
(signature)

Q9 What is the exhaust noise test specified in13 CCR? Can this be used for enforcement?



Sections 1030-1036, 13 CCR, were intended to be used by Licensed Muffler Certification Stations as a means of determining if an exhaust system met the requirements of the Muffler Certification Program (when those programs were operational). They specify testing procedures for motor vehicles exhaust noise alone (as opposed to total vehicle noise). This procedure specifies a limit of 95 dB(A) measured 20 inches from the exhaust pipe outlet with the engine operating in neutral, typically at a speed of 3000-5000 rpm. (For comparison, a modern rotary lawn mower with a 5 horsepower Briggs & Stratton engine typically emits approximately 93 dB(A) at the same distance at full speed under no load.) It applies only to passenger vehicles. It does not apply to motorcycles or to vehicles over 6000 pounds gross weight.

I'm assuming you're talking about the Mustang car? Mustangs, porky Mercedes, and most SUV's are under 6k lbs (most cars weigh around 3k-4.5k lbs)
