What is the primary advantage of keeping the rear of the vehicle close to the curb while turning?

Keeping the rear of the vehicle close to the curb while turning primarily helps to prevent other drivers from passing on the right. This positioning creates a clear boundary for your vehicle and enhances safety by minimizing the risk of collisions with vehicles approaching from the right side. When you maintain a tight turn close to the curb, it also signals to other road users that you are about to make a turn, which aids in communication and situational awareness on the road. This is particularly important in urban settings where lane space may be limited, and there may be other road users, like cyclists and pedestrians, sharing the space.

The other options may relate to driving principles, but they do not directly address the benefits of keeping close to the curb. For example, while faster turns can be advantageous in certain situations, they do not account for the increased risk of accidents or loss of control. Fuel efficiency and visibility considerations are also not directly linked to the specific action of positioning the rear of the vehicle near the curb during a turn.
