What is a possible indicator of a driver’s lack of response during a stop?

A lack of response from a driver during a stop can indicate a potential impairment or other issues that may affect the driver’s cognitive or physical abilities. When a driver shows no response, it may suggest they are not processing information correctly or are unresponsive to the presence of law enforcement. This behavior could point to various issues, including intoxication, medical emergencies, or other impairments that affect their ability to react appropriately in a high-stress situation.

In contrast, other behaviors such as instantly pulling over, quick compliance, or pointing to the side of the road demonstrate a more engaged and aware driver. These actions indicate an acknowledgment of law enforcement's presence and typically signify that the driver is capable of understanding and responding to instructions. Hence, the absence of any response becomes a crucial indicator of potential intoxication or other issues that warrant further investigation.
