placement of traffic control devices near schools for the purpose of
protecting students going to and from school. Such devices may
include flashing signals. Such warrants shall be based upon, but
need not be limited to, the following items: pedestrian volumes,
vehicle volumes, width of the roadway, physical terrain, speed of
vehicle traffic, horizontal and vertical alignment of the roadway,
the distance to existing traffic control devices, proximity to the
school, and the degree of urban or rural environment of the area.
21373. The governing board of any school district may request the
appropriate city, county, city and county or state agency to install
traffic control devices in accordance with the warrants established
pursuant to Section 21372. Within 90 days thereafter, the city,
county, city and county or state agency involved shall undertake an
engineering and traffic survey to determine whether the requested
crossing protection meets the warrants established pursuant to
Section 21372. The city, county, city and county, or state agency
involved may require the requesting school district to pay an amount
not to exceed 50 percent of the cost of the survey. If it is
determined that such requested protection is warranted, it shall be
installed by the city, county, city and county or state agency
21374. A local authority may mark or paint the surface of any
street or highway under its jurisdiction, or of any state highway,
with the approval of the Department of Transportation, with lines,
arrows, or other suitable symbols for the purpose of directing
visitors and tourists to local points of interest. No such marking
shall be of a color or configuration which, as determined by the
Department of Transportation, would cause it to be confused with an
official traffic control device.
21375. (a) The Department of Transportation shall place and
maintain, or cause to be placed and maintained, directional signs on
freeways indicating the location of the freeway off ramp which may be
used to reach a public or private postsecondary education
