A three-lane road has a center lane bordered by an outside solid yellow line and an inside broken yellow line on each side. How may drivers use this center lane?
-
A.
Only as a merge lane for entering traffic
-
B.
Only to pass slower vehicles
-
C.
Only to make left turns Correct
-
D.
As a shared travel lane in either direction
The answer is "Only to make left turns"
The outside solid yellow line means the center lane cannot be used for passing; the inside broken yellow lines mean traffic from either direction may enter the center lane only to make left turns. B tempts a driver who reads any center lane as a passing lane and overlooks what the outer solid boundary is telling them.
The traps in the wrong answers
A. Only as a merge lane for entering traffic
Merge lanes are on entrance ramps and are marked differently; this is a left-turn lane. This answer imports highway on-ramp merging into a mid-block turn-lane setup.
B. Only to pass slower vehicles
The outside solid yellow line specifically forbids using the center lane for passing. This answer reads any center lane as a passing lane and ignores the outer solid boundary.
D. As a shared travel lane in either direction
The center lane is not a through-travel lane; it is a turn refuge only. This answer mistakes the two-way striping for shared open travel.
