Knowing the vehicle's turning radius is crucial for safely navigating tight turns. This awareness allows the driver to understand how much space is needed for the vehicle to make the turn without encroaching on adjacent lanes or obstacles. Each vehicle has a different turning radius based on its size and design, so being familiar with this characteristic helps the driver plan their maneuvers more effectively.

When drivers know their vehicle's turning radius, they can adjust their approach and position on the road before initiating a turn, ensuring they stay in their lane and avoid any potential hazards. This preventive measure can significantly reduce the risk of collisions and improve overall safety.

In contrast, increasing speed while turning can lead to loss of control, and using only mirrors may not provide a complete view of the surrounding environment. Relying solely on intuition can also be unreliable, as it may lead to poor judgment of space and vehicle capabilities. The best option promotes knowledge of the vehicle's specific handling characteristics, which is critical for safe navigation in tight spaces.
