What driving behavior is commonly associated with impaired drivers?

Impaired drivers often exhibit erratic behaviors due to a lack of coordination, slowed reaction times, and impaired judgment. Sudden stops and swerving are common signs of impairment as they stem from an inability to maintain control over the vehicle. For instance, an impaired driver might misjudge distances or misinterpret other drivers' actions, resulting in abrupt maneuvers to avoid obstacles or correct a course. These behaviors can pose serious risks to the driver and others on the road, highlighting the dangers of impaired driving.

While maintaining a consistent speed typically indicates a driver who is focused and in control, behaviors like frequent lane changes and driving in reverse can occur for various reasons unrelated to impairment, such as navigating through traffic or looking for a turn. However, when these actions are performed erratically or without clear purpose, they become more characteristic of impairment.
