Learn the telltale signs of drunk driving, which number to call to report a drunk driver, and how to report the event to authorities.
Spot the Signs of Drunk Driving
There are telltale signs that the driver of a vehicle is impaired. While these behaviors do not guarantee that a driver is drunk, they still indicate the driver is a safety threat and should be reported to the police.¹
Signs of drunk driving:
Swerving or slowing below the speed limit
Erratic braking and acceleration
Sudden, abrupt turns
Driving down the center of a road, straddling lanes
Driving on the wrong side of the road
Stopping inappropriately in traffic
Failure to respond to traffic signals
If you do spot a driver showing signs of impairment, make sure you’re safely out of their path of travel before calling 911. The last thing you need is to become involved in a traffic accident while trying to report the driver.²
How to Report a Drunk Driver
To report a drunk driver, call 911. Give the operator as complete a description of the vehicle as possible. Local police or highway patrol can’t pull over the drunk driver if they don’t know who they’re looking for.
Details to Provide When Reporting a Drunk Driver
Gather these details for the dispatcher before calling 911 to report a vehicle for erratic driving:
License plate number
Make, model, and color of the car
Location of the vehicle, including street names or intersections
If you’re not driving, taking a picture of the vehicle and the license plate number with your phone may be helpful. If you’ve got a dash cam that can capture those details, even better.
Be prepared to describe why you have a reasonable suspicion the driver is drunk, including any unsafe driving behaviors you witnessed.

What happens if you report a drunk driver?
Because drunk driving isillegal, when you report a drunk driver, law enforcement will attempt to find the vehicle and assess whether the driver is impaired. If they have reasonable suspicion of alcohol or drug use, police conduct a field sobriety test. If the motorist fails the field sobriety test, they will be arrested and their vehicle impounded.
Can I anonymously report a drunk driver?
In order to prevent drunk driving deaths and other fatalities, police encourage drivers to report any behavior on the road that seems unsafe. You’re not required to provide your name if you’d prefer to anonymously report a drunk driver or aggressive driving.
Can you report a drunk driver after the fact?
While it’s best to report a drunk driver immediately so law enforcement can get them off the road and prevent crashes, it’s also important that you stay safe. That may mean you need to wait until you arrive home to report a drunk driver.
