§ 1139a. Bicycle control signals
(a) Bicycles shall obey bicycle-control signals. An individual operating a bicycle shall obey the instructions of a bicycle-control
signal, if present, instead of any traffic-control signal for motor vehicles.
(b) Bicycle-control signal legend.
(1) Green bicycle signal.
(A) An individual operating a bicycle facing a green bicycle signal may proceed straight
through the intersection or turn right or left unless a sign prohibits such a turn,
provided that:
(i) the individual operating the bicycle will not be in conflict with any simultaneous
motor vehicle movements at that location; or
(ii) the bicycle movement at that location is not modified by lane-use signs, turn-prohibition
signs, pavement markings, separate turn signal indications, or other traffic-control
devices.
(B) An individual operating a bicycle pursuant to a green bicycle signal, including when
turning right and left, shall yield the right-of-way to other individuals operating
bicycles and pedestrians that are in the intersection when the signal is exhibited.
(2) Steady yellow bicycle signal. An individual operating a bicycle facing a steady yellow bicycle signal is warned
that the steady green signal is being terminated and that the red signal will be exhibited
immediately following the steady yellow signal, at which time bicycle traffic traveling
in that direction shall not enter the intersection.
(3) Steady red bicycle signal.
(A) An individual operating a bicycle facing a steady red bicycle signal alone shall stop
at a clearly marked stop line, or if there is none, shall stop before entering the
crosswalk on the near side of the intersection.
(B) Except when a sign is in place prohibiting a turn, an individual operating a bicycle
facing a steady red bicycle signal may:
(i) cautiously enter the intersection to turn right; or
(ii) after stopping as required pursuant to subdivision (A) of this subdivision (b)(3),
turn left from a one-way street onto a one-way street.
(C) An individual making a turn pursuant to subdivision (B) of this subdivision (b)(3)
shall yield the right-of-way to pedestrians and other vehicles that are in the intersection.
(D) An individual operating a bicycle shall not turn right when facing a red arrow signal
unless a sign permitting such a turn is present.
(E) An individual operating a bicycle to the left of adjacent motor vehicle traffic approaching
the same intersection shall be prohibited from turning right when facing a steady
red bicycle signal and an individual operating a bicycle to the right of adjacent
motor vehicle traffic approaching the same intersection shall be prohibited from turning
left when facing a steady red bicycle signal. (Added 2025, No. 66, § 42, eff. July 1, 2025.)
