Just to be clear, when referring to the relevant portions of the California Vehicle Code and the Los Angeles County Code applicable to taco trucks, here is the actual text of the law:
Vending from Vehicles
22455. (a) The driver of any commercial vehicle engaged in vending upon a street may vend products on a street in a residence district only after bringing the vehicle to a complete stop and lawfully ( )1 parking adjacent to the curb, consistent with the requirements of Chapter 9 (commencing with Section 22500) and local ordinances adopted pursuant thereto.
(b) ( )2 Notwithstanding subdivision (a) of Section 114315 of the Health and Safety Code or any other provision of law, a local authority may, by ordinance or resolution, adopt additional requirements for the public safety regulating the type of vending and the time, place, and manner of vending from vehicles upon any street.
Amended Sec. 3, Ch. 139, Stats. 2008. Effective January 1, 2009.
The 2008 amendment added the italicized material, and at the point(s) indicated, deleted the following:
2. “A local authority may, by ordinance or resolution, adopt additional requirements for the public safety regulating any type of vending from vehicles upon any street.”
And the newly adopted Los Angeles County Code 7.62.070:
