When completing a turn onto a multiple lane street:

The correct choice emphasizes the importance of safely aligning your vehicle with the appropriate lane based on your intended direction of travel when turning onto a multiple lane street. Selecting the closest available lane in your desired direction ensures minimal disruption to traffic flow and enhances safety by reducing the potential for collisions with other vehicles. This practice allows you to position your vehicle effectively and comply with the flow of traffic, which is essential for maintaining safety on the road.

The other choices do not properly address the nuances of safe lane selection during a turn. Selecting the rightmost lane solely because it is the slowest lane can lead to confusion and may not be the best lane for your intended direction. Choosing the leftmost lane based on the assumption it is the fastest can result in improper lane changes and unsafe conditions, as that lane may not align with your desired path. Always choosing the center lane is overly simplistic and may not be appropriate based on road signs, traffic directions, or specific turn requirements, which can vary depending on the intersection. Therefore, the most logical and safe approach is to select the closest lane that corresponds to your direction of travel.
