To Report an Impaired Driver

It happens every day. Drunk drivers get on the roads, endangering our friends and loved ones. Sometimes, we witness these drivers weaving in and out of lanes or traveling in the wrong direction. Often we find ourselves asking - What do I do?

First and foremost, stay as far away from the other vehicle.

Second, do not try to pass or signal the driver to pull over.

Third, without compromising your on safety, attempt to notice the license plate along with details about the vehicle i.e. make, model and color.

Finally, pull over, and call 911. Those in Colorado can also call *CSP (*277) to report an impaired driver.
