Which procedure varies according to whether a traffic stop is low risk or high risk?

The position of the patrol car during a traffic stop is indeed influenced by whether the situation is assessed as low risk or high risk. In a low-risk scenario, the officer may position their patrol car in a standard or routine manner, allowing for easier communication with the driver and a clear line of sight for both parties.

However, in high-risk situations, the positioning becomes much more tactical. Officers may angle the patrol car to create a barrier or increase their own safety by positioning it to protect the officer from potential threats. This strategic placement can help mitigate risks in the event that the encounter escalates. Therefore, understanding the distinction in car positioning based on the risk level is crucial for ensuring the officer's safety and the effectiveness of the stop.

While other options like calling for backup, using lights and sirens, and recording the stop may also differ depending on the circumstances, the physical placement of the patrol car is directly impacted by the perceived level of risk associated with the traffic stop.
