What does a roll refer to in vehicle handling?

In vehicle handling, a roll refers to the weight shift to the outside tires during a turn. This phenomenon occurs when a vehicle corners and the centrifugal force pushes the vehicle's weight outward, causing the suspension to compress on the outside tires and extend on the inside tires. This helps in maintaining traction on the tires that are more loaded, providing better grip and stability during the turn.

Understanding this concept is crucial for safe driving because it emphasizes the importance of vehicle dynamics, particularly in cornering situations. Properly managing roll can lead to better handling characteristics and aid in preventing loss of control, which is vital for both safety and performance.
