What is a cue that may indicate a driver is under the influence during a traffic stop?

The indication of a slow response during a traffic stop can be a significant cue that a driver may be under the influence of alcohol or drugs. This behavior suggests that the driver is having difficulty processing information, which is often associated with impaired cognitive functions. When an officer approaches a vehicle and the driver takes an unusually long time to respond to questions or instructions, it raises suspicion that their faculties may be compromised.

In driving scenarios, a driver's ability to react promptly is crucial for safety, and any delays can signal potential impairment. Noticing this cue, alongside other signs of impairment, helps officers form a reasonable suspicion to investigate further. Suspicion can also be heightened if the slow response is coupled with other behaviors commonly associated with intoxication.

Other options, such as consistent lane position and polite interaction, would generally demonstrate that a driver is managing their driving behavior effectively and does not exhibit signs of impairment. No sudden stops may not provide clear evidence of intoxication either, as various factors can contribute to stopping patterns that are not necessarily related to alcohol or drug use.
