When using a Stop Stick, one should always exercise extreme caution in which situation?

The correct answer focuses on the need for extreme caution when dealing with excessive speeds while using a Stop Stick. This is crucial because high-speed pursuits can escalate quickly and result in dangerous situations for both law enforcement officers and the public. The dynamics of a vehicle traveling at high speeds can change rapidly; deploying a Stop Stick in such circumstances could lead to loss of vehicle control, causing the suspect to crash or potentially injure bystanders. Thus, approaching the situation with caution in these scenarios is essential for ensuring safety.

The other scenarios, while they may also require caution, do not present the same level of immediate risk as excessive speeds. For example, when the suspect is calm, the situation might be more manageable. Similarly, the absence of pedestrians may reduce risk, and dealing with a suspect on a motorcycle, while it involves specific challenges, does not inherently pose the same level of danger as excessive vehicle speeds.
