What are typical signs of a driver who may be impaired?

The signs of a driver who may be impaired often include erratic behaviors that indicate a lack of control and attention. Erratic speed, lane drifting, and sudden stops are key indicators of impairment. These behaviors can signal that a driver is struggling to maintain focus or control over their vehicle, which is commonly associated with alcohol or drug use.

In contrast, consistent speed and proper lane positioning suggest that a driver is attentive and in control, which is not indicative of impairment. Similarly, frequent signaling and smooth acceleration indicate that a driver is following traffic rules and operating their vehicle responsibly. Maintaining a safe following distance is further evidence of a driver who is aware of their surroundings and capable of responding appropriately to traffic conditions. Thus, option B accurately reflects the dangerous driving behaviors associated with impairment.
