A two-way left turn lane in the center of a roadway is used for what purpose?
-
A.
Making U-turns whenever traffic seems clear
-
B.
Emergency and construction vehicle access only
-
C.
Passing slower vehicles that are going your way
-
D.
Left turns at intersections or into or out of a drive mid-block Correct
The answer is "Left turns at intersections or into or out of a drive mid-block"
A two-way left turn lane is set aside for left turns at intersections and for turns into or out of a drive mid-block. Option C is the trap for drivers who see a wide painted center lane and treat it as a general-purpose passing lane.
The traps in the wrong answers
A. Making U-turns whenever traffic seems clear
The lane is set aside for left turns; a U-turn is legal only where visibility and local ordinances allow it. This answer reads the center turn lane as an anywhere, anytime U-turn zone and ignores the 500-foot visibility rule on curves and hills and municipal U-turn prohibitions.
B. Emergency and construction vehicle access only
The lane is open to any driver making a legal left turn. This answer confuses the center two-way left turn lane with the divided-highway median openings that are restricted to emergency and maintenance use.
C. Passing slower vehicles that are going your way
The center lane is set aside for left turns, not for passing. This answer borrows the 'faster traffic keeps left' habit from interstate driving and applies it to a center turn lane, which serves neither direction as a passing lane.
