(2) A particular section of a highway with a prima facie speed
limit that is provided by this code or by local ordinance under
subparagraph (A) of paragraph (2) of subdivision (a) of Section
22352, or established under Section 22354, 22357, 22358, or 22358.3,
if that prima facie speed limit is not justified by an engineering
and traffic survey conducted within five years prior to the date of
the alleged violation, and enforcement of the speed limit involves
the use of radar or any other electronic device that measures the
speed of moving objects. This paragraph does not apply to a local
street, road, or school zone.

defined by the latest functional usage and federal-aid system maps
submitted to the federal Highway Administration, except that when
these maps have not been submitted, or when the street or road is not
shown on the maps, a "local street or road" means a street or road
that primarily provides access to abutting residential property and
meets the following three conditions:
(A) Roadway width of not more than 40 feet.
(B) Not more than one-half of a mile of uninterrupted length.
Interruptions shall include official traffic control signals as
defined in Section 445.
