the place prohibits either turn.
(B) Vehicular traffic, including vehicles turning right or left,
shall yield the right-of-way to other vehicles and to
pedestrians lawfully within the intersection or an adjacent
sidewalk at the time the signal is exhibited.
(C) Vehicular traffic facing a green arrow signal, shown
alone or in combination with another indication, may
cautiously enter the intersection only to make the movement
indicated by the green arrow or other movement permitted
by other indications shown at the same time.

pedestrians lawfully within an adjacent crosswalk and to
other traffic lawfully using the intersection.

pedestrians facing a green signal, except when the sole green
signal is a turn arrow, may proceed across the roadway
within a marked or unmarked crosswalk.
(2) Steady yellow indication means the following:
(A) Vehicular traffic facing a steady circular yellow or
yellow arrow signal is warned that the related green
movement is being terminated and that a red indication will
be exhibited immediately thereafter.

control signal, is advised that there is insufficient time to
cross the roadway before a red indication is shown, and a
pedestrian may not start to cross the roadway at that time.
(3) Steady red indication means the following:
(A) Except as provided in clause (B), vehicular traffic facing
a steady circular red or red arrow signal shall stop at a
clearly marked stop line. However, if there is no clearly

intersection and shall remain standing until an indication to
proceed is shown.

adjacent crosswalk and to other traffic using the intersection.
(C) Unless otherwise directed by a pedestrian control signal
pedestrians facing a steady circular red or red arrow signal
may not enter the roadway.

following:
(A) Vehicular traffic facing an intersection having a signal
that displays no indication or conflicting indications, where
no other control is present, shall stop before entering the
intersection.

caution through the intersection and shall yield the
right-of-way to traffic within the intersection or approaching
so closely as to constitute an immediate hazard.
(5) This section applies to traffic control signals located at a

flashes, a person who drives a vehicle shall stop at a clearly
marked stop line before entering the crosswalk on the near
side of the intersection.

the intersecting roadway where the person has a view of
approaching traffic on the intersecting roadway before
entering the roadway.
(C) The right to proceed is subject to the rules applicable
after making a stop at a stop sign.
(2) Flashing yellow (caution signal) means that when a yellow
lens is illuminated with rapid intermittent flashes, a person who
drives a vehicle may proceed through the intersection or past
the signal only with caution.
