What are some signs of an impaired driver?

The signs of an impaired driver often include erratic behavior that deviates from safe and typical driving patterns. Specifically, swerving indicates a lack of control over the vehicle, which can suggest that the driver is unable to maintain a straight path due to impairment. Erratic speed shows that the driver is either accelerating or decelerating unpredictably, which is not a normal behavior for sober drivers. Sudden stops can be a result of impaired judgment, where the driver may decide to stop the vehicle abruptly without a clear reason. These behaviors can signal to others on the road that the driver may be under the influence of drugs, alcohol, or is suffering from some other impairment. This combination of signs serves as a clear warning to other road users about the potential dangers posed by the impaired driver.
