A "highway" is defined thus:
360. "Highway" is a way or place of whatever nature, publicly
maintained and open to the use of the public for purposes of
vehicular travel. Highway includes street.
As for the violation, were you actually cited for CVC 22100(a)?
If so, here is that violation:
22100. Except as provided in Section 22100.5 or 22101, the driver
of any vehicle intending to turn upon a highway shall do so as
(a) Right Turns. Both the approach for a right-hand turn and a
right-hand turn shall be made as close as practicable to the
right-hand curb or edge of the roadway except:
(1) Upon a highway having three marked lanes for traffic moving in
one direction that terminates at an intersecting highway
accommodating traffic in both directions, the driver of a vehicle in
the middle lane may turn right into any lane lawfully available to
traffic moving in that direction upon the roadway being entered.
(2) If a right-hand turn is made from a one-way highway at an
intersection, a driver shall approach the turn as provided in this
subdivision and shall complete the turn in any lane lawfully
available to traffic moving in that direction upon the roadway being
(3) Upon a highway having an additional lane or lanes marked for a
right turn by appropriate signs or markings, the driver of a vehicle
may turn right from any lane designated and marked for that turning
As such, if you never made a right hand turn it would seem the incorrect section. What did he tell you that you did wrong? That might help us figure out what he intended to cite you for.
