This sign means
- two-way left turn lane ✓
- all traffic must turn left ahead
- this lane must turn left or right ahead
- left turns only at this intersection
Answer: A. two-way left turn lane
The sign means a two-way left-turn lane: a centre lane shared by drivers from both directions who are turning left.
Why this is the answer
The handbook describes two-way left-turn lanes as centre lanes that let left-turning vehicles from either direction turn without holding up traffic. Drivers going both ways share the lane when they want to turn left, including for a mid-block turn such as into a driveway. Because opposite-direction traffic may also use it, you should check that there is enough space before entering and watch for vehicles coming toward you. That matches the meaning of a two-way left-turn lane, not a lane that forces every driver to turn or restricts left turns to an intersection.
Why the other answers are wrong
- B. all traffic must turn left ahead — This is wrong because the lane is for left-turning vehicles from either direction, not a rule that all traffic ahead must turn left.
- C. this lane must turn left or right ahead — This is wrong because the handbook describes a lane used for left turns, not a lane where you must turn either left or right.
- D. left turns only at this intersection — This is wrong because the handbook says the lane can be used for a mid-block left turn, such as into a driveway, so left turns are not limited to an intersection.
Remember it
Picture a shared middle lane: left-turners from both sides borrow it, so check the other direction before you move in.
