Which behavior might indicate that a driver is impaired?

Driving behavior that involves weaving from side to side can be a clear indication that a driver may be impaired. When a driver is unable to maintain a steady course within their lane, it often suggests a lack of coordination or control, which are common effects of impairment due to substances like alcohol or drugs.

Impaired drivers may struggle to keep their car centered in the lane, leading to erratic movements and potentially dangerous situations for themselves and other road users. This behavior can be a critical factor for law enforcement and other drivers in identifying someone who may need assistance or intervention.

In contrast, behaviors such as consistently driving at the speed limit, using turn signals frequently, or maintaining a straight path suggest safe and responsible driving practices. These actions typically indicate that a driver is attentive and in control, which is the opposite of the erratic driving patterns associated with impairment.
