Through my recent experience with an aggressive driver, I’ve come up with some solutions to prevent a terrifying incident like one that happened to my wife and me recently on River Road near Tacoma.
In most instances, driving the speed limit should spare you the wrath of an irrational driver. If you're being tailgated and the other driver is flashing lights, just change lanes and let him pass. Never pull over and stop your car. Never slow down; this will make things worse. Never speed up unless it’s your last resort.
Avoid eye contact at all times. Know your whereabouts, so if this event turns violent you can drive to a public area for help. This should discourage the other driver, and he'll back off.
In my case, the aggressive driver became violent. If this happens, I encourage you to use your cellphone and let the police know what’s happening and where you are headed. Never drive towards your home or a relative’s residence. If you follow these steps you should feel safe on the open road.
If you really fear for your life I only suggest one solution: Get to a public area as soon as you can. But don't drive so fast that you endanger other drivers.
