Actually "speed traps" aren't a valid form of capturing evidence.
Anyway they can, from speed traps to ... well, don't get me started.
From the CVC
where a speed trap is defined as
40804. (a) In any prosecution under this code upon a charge
involving the speed of a vehicle, an officer or other person shall be
incompetent as a witness if the testimony is based upon or obtained
from or by the maintenance or use of a speed trap.
(a) A "speed trap" is either of the following:
(1) A particular section of a highway measured as to distance and
with boundaries marked, designated, or otherwise determined in order
that the speed of a vehicle may be calculated by securing the time it
takes the vehicle to travel the known distance.
(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.
