What does "Dial" refer to in the 4 Apex Approach Rule?

The term "Dial" in the 4 Apex Approach Rule specifically refers to turning the steering wheel to match the necessary angle for the maneuver being executed. To successfully navigate curves or turns, operators must adjust their steering input effectively to align the vehicle's path with the intended trajectory. This ensures that the vehicle maintains control and stability, particularly at higher speeds, while also allowing for a smoother cornering process.

Choosing the correct steering angle is crucial because it helps in avoiding oversteering or understeering, both of which can lead to a loss of control. By 'dialing' in the steering, the operator can respond appropriately to the dynamics of the vehicle in relation to the roadway and surrounding obstacles. It emphasizes the importance of precise steering control in emergency vehicle operations, which can significantly impact safety and performance during high-stress situations.
