Left On Green Arrow Only

Left turns are permitted only when the green arrow is showing.

Used at signalized intersections with protected-only left-turn phasing. Drivers in the left-turn lane may turn only while the green left-arrow is illuminated; a circular green ball does not authorize a left turn at this approach. Waiting in the intersection for a gap is not permitted.
