23130. (a) No person shall operate either a motor vehicle or combination of vehicles of a type subject to registration at any time or under any condition of grade, load, acceleration, or deceleration in such a manner as to exceed the following noise limit for the category of motor vehicle within the speed limits specified in this section:
(b) The noise limits established by this section shall be based on a distance of 50 feet from the center of the lane of travel within the speed limit specified in this section. The Department of the California Highway Patrol may provide for measuring at distances other than 50 feet from the center of the lane of travel. In such a case, the measurement shall be corrected so as to provide for measurements equivalent to the noise limit established by this section measured at 50 feet.
(c) The department shall adopt regulations establishing the test procedures and instrumentation to be utilized. These procedures shall allow, to the extent feasible, noise measurement and enforcement action to be accomplished in reasonably confined areas such as residential areas of urban cities.
(d) This section applies to the total noise from a vehicle or combination of vehicles and shall not be construed as limiting or precluding the enforcement of any other provisions of this code relating to motor vehicle exhaust noise.
(e) For the purpose of this section, a motortruck, truck tractor, or bus that is not equipped with an identification plate or marking bearing the manufacturer's name and manufacturer's gross vehicle weight rating shall be considered as having a manufacturer's gross vehicle weight rating of more than 10,000 pounds if the unladen weight is more than 5,000 pounds.
(f) No person shall have a cause of action relating to the provisions of this section against a manufacturer of a vehicle or a component part thereof on a theory based upon breach of express or implied warranty unless it is alleged and proved that such manufacturer did not comply with noise limit standards of the Vehicle Code applicable to manufacturers and in effect at the time such vehicle or component part was first sold for purposes other than resale.
