A regulatory Turn Lanes sign shows a left-turn arrow above the left lane and a combined left-turn and straight arrow above the lane beside it. What may drivers in the second lane from the left do?
-
A.
Straight through only; left turns are forbidden.
-
B.
Left or right turn allowed; straight is forbidden.
-
C.
Left turn only; continuing straight is forbidden.
-
D.
Left turn or straight through, at the driver's choice. Correct
The answer is "Left turn or straight through, at the driver's choice."
On the Turn Lanes sign, the left lane is turn-only while the adjoining lane may turn left or continue straight. The Left Lane Must Turn rule stretched one lane to the right shows up as choice C, treating any lane whose overhead sign shows a left arrow as turn-only.
The traps in the wrong answers
A. Straight through only; left turns are forbidden.
The left arrow above the adjoining lane keeps the left-turn option open. This answer splits the paired arrows between the two lanes, assigning the left arrow to the leftmost lane and leaving only the straight-ahead permission for the second.
B. Left or right turn allowed; straight is forbidden.
Turn Lanes does not authorize a right turn from the adjoining lane; the arrows shown are straight and left. This answer confuses Turn Lanes with the Must Turn sign, which is the one that lets a driver pick right or left instead of going straight.
C. Left turn only; continuing straight is forbidden.
Left Lane Must Turn applies only to the leftmost lane; the adjoining lane is not restricted to a left turn. This answer carries the Left Lane Must Turn rule one lane to the right, treating any lane whose overhead sign shows a left arrow as turn-only.
