If driving a long vehicle making a left turn from a two-lane street, which turn lane should you use?

When making a left turn from a two-lane street in a long vehicle, it is important to use the appropriate turn lane to ensure safety and compliance with traffic regulations. Using the left turn lane “B” is correct because this lane is typically positioned to allow for a safer and more efficient turn. It keeps the long vehicle aligned with its intended direction, reducing the risk of encroaching into the adjacent lanes or conflicting with oncoming traffic.

Using left turn lane "A" could potentially cause the vehicle to cross over more lanes than necessary, increasing the chances of collision with other vehicles or pedestrians. While "C" suggests that either lane is acceptable, this overlooks the specific dynamics and turning radius of long vehicles, which require more space and careful navigation.

As for turning from the right lane, while it may seem feasible in some situations, it is not advisable as it can lead to unintended consequences like backing into traffic or getting stuck in confusing intersections. Overall, the designated left turn lane "B" is specifically designed for such maneuvers, making it the safest and most effective choice for long vehicles.
