The key point to remember is that you are much safer in a moving vehicle, even a slow moving vehicle, than when in or around a stationary vehicle. So if you think you are being followed keep moving and consider the following strategies.
If you are able to, make three left (or three right) turns in a row. You have essentially just driven in a “square circle” as it were, and the likelihood that you are NOT being followed is now almost zero; anyone who is still following you after this route detection / evasion maneuver should be considered a serious threat. A less brazen person would probably terminate their pursuit knowing they have been spotted.
Now proceed at safe speeds to the closest busy road, preferably a well light boulevard or even a highway. Drive below the posted speed limit and turn on your hazard lights. This will draw attention to your vehicle.(In this situation you want to be pulled over by the police!) Slowing down also will allow you to get your bearings while operating the vehicle safely. While doing so initiate a 911 call. Try maintaining a consistent heading and make note of the cross streets. Most states require a hands free headset this making talking to the operator easier and safer.
Let the operator know you are being followed and then let the operator ask the questions. If you see a red light ahead, slow down and try time arriving at that intersection when the light is green so you don’t have to come to a full stop. If you have to come to a stop, leave a car length between you and the vehicle in front of you giving you space to maneuver if you have to. (You should make this a habit even if not being followed)
The operator will keep you on the line and he or she will direct a police car to intercept you.
This scenario is one reason it is always good to have more than half a tank of gas and to be always be generally aware of your location. A report in Seattle several years ago indicated that 25% of cell phone callers to 911 did not know enough about where they were making it almost impossible for emergency services to respond. Situational awareness is key.
In a situation like this it goes without saying you should not drive to work, home, your child’s school or any destination you frequent. This includes a friend’s house. If you will drive to a fire station or police station, let the operator know to which one you are heading so that a first responder can be curbside when you arrive. There have been cases where the person being followed has pulled into a busy grocery store lot in broad daylight and the perpetrator was brazen enough to still have tried to cut them off as they made their way on foot into the store.
