When making a turn, which wheel must pivot more sharply?

In the context of making a turn, the inside wheel must pivot more sharply because it has a shorter turning radius compared to the outside wheel. As a vehicle turns, the wheels on the inside of the turn travel a shorter distance than those on the outside. This is particularly significant in larger vehicles, where understanding pivot points is crucial for effective turning.

When a vehicle executes a turn, the inside wheels essentially pivot around a focal point that is located on the inner part of the turn's arc. This pivoting motion allows the vehicle to negotiate the turn without excessive steering input and helps prevent the rear of the vehicle from swinging out, maintaining overall control. Meanwhile, the outside wheels also maneuver but have a larger radius, which means they don't pivot as sharply as the inside wheels.

This concept is particularly important for drivers of larger vehicles, such as buses and trucks, since failing to account for the sharper turning needs of the inside wheels can lead to accidents, including collisions with obstacles or other vehicles. Understanding this principle contributes to better maneuvering skills and enhances safe driving practices.
