To make a left turn at an intersection, what should Vehicle A do first?

• A. Accelerate before turning
• B. Move to the left lane before crossing
• C. Signal after starting the turn
• D. Yield to oncoming traffic

Answer: (B)

Before making a left turn at an intersection, it is crucial for Vehicle A to first move to the left lane if it is not already positioned there. This allows the driver to prepare adequately for the turn, ensuring that they are in the correct lane to execute the maneuver safely and effectively. Positioning the vehicle properly reduces the risk of accidents and blockage of traffic.

By moving into the left lane, the driver not only prepares themselves for the turn but also communicates their intention to other road users, facilitating a smoother flow of traffic. This is particularly important in busy intersections where other vehicles may be present.

In contrast, accelerating before turning can lead to a loss of control and is unsafe. Signaling after starting the turn does not provide adequate notice to other drivers and pedestrians regarding the driver's intentions. Yielding to oncoming traffic is essential when making a turn; however, the correct initial action is to ensure the vehicle is positioned appropriately to perform the turn safely.
