Which of the following indicates a driver may be intoxicated?

The behavior of weaving within the lane and making sudden stops can indicate that a driver may be intoxicated. These actions suggest a lack of control over the vehicle, which is often a result of impaired judgment and coordination commonly associated with alcohol or drug consumption. Weaving may demonstrate that the driver is struggling to maintain a straight path, while sudden stops could imply difficulties in processing information or responding to traffic conditions, both of which are indicative of impairment. Observing these behaviors prompts law enforcement officers to suspect that a driver is not operating the vehicle safely and could warrant further investigation or a field sobriety test. Other choices, such as consistent speed or adherence to traffic rules, do not indicate impairment; rather, they showcase responsible driving behavior.
