    Driving in the center lane for several blocks to accelerate and merge into fast-moving traffic or pass slower vehicles ahead.
  3. C
    Stopping completely in the center lane to yield to oncoming traffic even when no vehicles are approaching from the opposite direction.
  4. D
    Continuing straight through an upcoming intersection while remaining inside the designated center lane.

Answer

Entering the center lane for a brief distance to prepare for and execute a left turn into a driveway or side street.
The option stating that drivers may enter the lane for a brief distance to prepare for and execute a left turn into a driveway or side street correctly states the legal purpose of a shared center turn lane under regulatory sign enforcement.

Step-by-Step Solution

1
Identify the type and regulatory meaning of the sign.
The white rectangular sign reading 'CENTER LANE LEFT TURN ONLY' is a mandatory regulatory sign governing lane usage.
Regulatory signs inform drivers of specific laws and mandatory lane operational rules.
2
Evaluate the permissible legal uses of a shared center left-turn lane.
Drivers may only enter this lane to make a left turn into or from an intersection, alley, or private driveway, typically within a maximum recommended distance (e.g., 200 feet).
Using the lane for passing, through-travel, or long-distance driving violates regulatory lane restrictions and creates collision risks with opposing traffic.
