     If you haven't heard or seen anything about Road Rage in the last few months, you've probably been

avoiding the media. There have been countless stories about this new and scary phenomenon, considered

a type of aggressive driving. You have most likely encountered aggressive driving or

Road Rage recently if you drive at all.  

     While drunk driving remains a critical problem, the facts about aggressive driving are surely as

disturbing. For instance, according to the National Highway Transportation Safety Association, 41,907

people died on the highway last year. Of those deaths, the agency estimates that  about two-thirds were

caused at least in part by aggressive driving behavior.

     Why is this phenomenon occurring more than ever now, and why is it something that seemed

almost nonexistent a few short years ago? Experts have several theories, and all are probably

partially correct. One suggestion is sheer overcrowding. In the last decade, the number of cars on

theroads has increased by more than 11 percent, and the number of miles driven has increased by 35

percent. However, the number of new road miles has only increased by 1 percent. That means more cars

in the same amount of space; and the problem is magnified in urban areas. Also, people have less time

and more things to do. With people working and trying to fit extra chores and activities into the day,

stress levels have never been higher. Stress creates anxiety, which leads to short tempers. These factors,

when combined in certain situations, can spell Road Rage.

     You may think you are the last person who would drive aggressively, but you might be

surprised. For instance, have you ever yelled out loud at a slower driver, sounded the horn long

and hard at another car, or sped up to keep another driver from passing? If you recognize yourself in any

of these situations, watch out!

     Whether you are getting angry at other drivers, or another driver is visibly upset with you,  there are

things you can do to avoid any major conflict. If you are susceptible(easily influenced) to Road Rage, the

key is to discharge your emotion in a healthy way. If you are the  target of another driver's rage, do

everything possible to get away from the other driver safely,  including avoiding eye contact and getting

out of their way.
