The Correct Answer and Explanation is :
The correct answer is:
Drivers may use this lane only to make a left turn.
Explanation:
Lane use control signals are often used to regulate traffic flow, particularly on roads with reversible lanes or heavy traffic. These signals inform drivers about which lanes are available or restricted for specific types of use.
A flashing yellow X in a lane use control signal means that the lane is open but only for specific purposes—usually for making left turns. This signal is common at intersections or areas where left turns are allowed but require caution. The flashing yellow X serves as a warning to proceed carefully and yield to oncoming traffic and pedestrians before making the turn.
Key Points:
- Purpose of the Signal:
The flashing yellow X indicates a conditional lane use. It allows drivers to use the lane only to make left turns, typically at intersections or driveways. - Contrast with Other Signals:
- A steady green arrow indicates full, unrestricted use of the lane in the direction indicated by the arrow.
- A steady yellow X warns that the lane is about to be closed (e.g., it will soon display a red X).
- A red X means the lane is closed to all traffic.
- Safety Considerations:
Drivers must be cautious while using a lane marked by a flashing yellow X. The signal often indicates potential conflicts, such as oncoming traffic or crossing pedestrians. Always yield the right of way where required and ensure the lane is clear before proceeding.
Understanding and adhering to lane use control signals like the flashing yellow X promotes safer and more efficient traffic flow, reducing the likelihood of accidents.
