What is critical speed defined as?

Critical speed is defined as the maximum speed at which a vehicle can safely navigate a turn without losing traction or stability. This concept is essential for fire service vehicle operators, as it directly impacts their ability to respond quickly and safely during emergencies. Understanding critical speed allows operators to make informed decisions while maneuvering their vehicles under various conditions, such as wet or icy roads, and ensures they maintain control.

In a situation where a vehicle exceeds this critical speed while taking a turn, it can lead to skidding or rolling over, compromising not only the safety of the operator but also that of other road users and the successful execution of the emergency response. Recognizing the importance of this speed in relation to vehicle dynamics is crucial for maintaining safety while still adhering to the urgent nature of fire service operations.
