Which of the following indicates a potential intoxicated driver?

Each of the behaviors listed in the options serves as a potential indicator of an intoxicated driver.

Sudden lane changes can signify a lack of control or impaired judgment, prompting a driver to unpredictably maneuver through traffic. This erratic driving pattern is often observed when someone is under the influence, as their perception of safety and distance can be compromised.

Weaving in and out of traffic is another common sign of intoxication. This behavior may indicate that the driver is having difficulty maintaining a straight path or spatial awareness, which are both critical for safe driving. Intoxicants can severely affect motor skills and reaction times, leading to this type of driving pattern.

Driving exceptionally slow might also suggest an intoxicated driver. While slower speeds can sometimes indicate caution, they can also result from impaired judgment where a driver may be overly cautious or not able to accurately gauge the appropriate speed for road conditions.

Given that all these driving behaviors can be linked to impaired abilities, the choice that encompasses all these signs is the most comprehensive and accurate indicator of a potential intoxicated driver.
