Even if you refrain from drinking and driving, you cannot control what other motorists do. Accordingly, you may encounter an impaired driver on the road, which can be hazardous for you and others. Here are the steps to take to possibly prevent a drunk driver from causing an accident. 

Know what to look for 

There are certain signs that point to an inebriated driver. Weaving within the lane, or even out of the lane, wrongly signaling, driving well below the speed limit, driving without lights on, making illegal turns, almost hitting an object or another vehicle, and sudden stops are all indications that a driver may be inebriated by drugs or alcohol. 

Keep your distance 

If you notice the above signs, leave ample room between your vehicle and the suspected drunk driver. While you may want to pass and get as far away from the car as possible, it is best to remain behind it. Leave enough space so that you have enough time to stop in case the driver makes a sudden maneuver. 

Try to take down the license number 

It is important that you maintain control of your vehicle, but if it is safe to do so, try to read as much of the license plate number as possible. Even if you are only able to remember a few letters or digits, it could be enough for the police to apprehend the person. Also, take note of the make, model, and color of the vehicle if possible. 

Contact the police 

When you can, pull over in a safe place and call the police. Provide them as much information as you have about the vehicle and the plate number, as well as the location of the driver, including nearby cross streets. You may also be asked about the behavior of the driver and what made you believe he or she was impaired. Do not pursue the driver yourself. Not only will you endanger yourself, you may also endanger others.
