There is probably not a day that goes by when you see someone taking unnecessary driving risks. If you are like most individuals, this can make you quite uncomfortable—maybe even angry at times. Without a doubt, aggressive driving is a serious and growing problem. It is rude, often illegal, and always dangerous. Speeding, tailgating, frequent and sudden lane changes, failure to yield right-of-way and disregarding traffic signals—these aggressive behaviors are contributing factors in more than 50 percent of all collisions.
