(a) A motor vehicle, when operated upon a highway, shall be equipped with a horn in good working order and capable of emitting sound audible under normal conditions from a distance of not less than 200 feet, but no horn shall emit an unreasonably loud or harsh sound.

The backup device or alarm shall also be capable of operating automatically when the vehicle is in neutral or a forward gear but rolls backward.

(c) A refuse or garbage truck, except a vehicle, known as a rolloff vehicle, that is used for the express purpose of transporting waste containers such as open boxes or compactors, purchased after January 1, 2010, shall also be equipped with a functioning camera providing a video display for the driver that enhances or supplements the driver’s view behind the truck for the purpose of safely maneuvering the truck.

(d) (1) A construction vehicle with a gross vehicle weight rating (GVWR) in excess of 14,000 pounds that operates at, or transports construction or industrial materials to and from, a mine or construction site, or both, shall be equipped with an automatic backup audible alarm that sounds on backing and is capable of emitting sound audible under normal conditions from a distance of not less than 200 feet.

(a) The driver of a motor vehicle when reasonably necessary to insure safe operation shall give audible warning with his horn.

(Amended by Stats. 1977, Ch. 993.)

No vehicle, except an authorized emergency vehicle, shall be equipped with, nor shall any person use upon a vehicle any siren except that an authorized emergency vehicle shall be equipped with a siren meeting requirements established by the department.

(Amended by Stats. 1979, Ch. 723.)

27003.
  

An armored car may be equipped with a siren which may be used while resisting armed robbery. At all other times, the siren shall not be sounded.

(Enacted by Stats. 1959, Ch. 3.)

27007.
  

No driver of a vehicle shall operate, or permit the operation of, any sound amplification system which can be heard outside the vehicle from 50 or more feet when the vehicle is being operated upon a highway, unless that system is being operated to request assistance or warn of a hazardous situation.

This section does not apply to authorized emergency vehicles or vehicles operated by gas, electric, communications, or water utilities. This section does not apply to the sound systems of vehicles used for advertising, or in parades, political or other special events, except that the use of sound systems on those vehicles may be prohibited by a local authority by ordinance or resolution.
