What is a common indicator of alcohol impairment during a traffic stop?

Erratic driving behavior is a well-documented indicator of alcohol impairment. When a driver is under the influence of alcohol, their ability to operate a vehicle safely is compromised. This can manifest in various ways, such as weaving in and out of lanes, sudden braking or acceleration, failing to adhere to traffic signals, or driving significantly below the speed limit. Law enforcement officers are trained to recognize these patterns of driving as potential signs of impairment, which can prompt further investigation during a traffic stop.

Other factors, such as speeding violations or excessive noise from the vehicle, may indicate reckless behavior or vehicle condition issues but are not specific indicators of alcohol impairment. Worn tires, while potentially dangerous, do not directly relate to the driver’s state of impairment. Therefore, erratic driving behavior is the most indicative sign that a driver may be under the influence of alcohol.
