Can driving while angry be just as dangerous as driving under the influence of alcohol?

It can be if you let your anger overrule your good sense. Anger can cloud your perceptions, it can cause you to be more aggressive, and it can cause you to take it out on innocent bystanders. If you are not in control, the vehicle is not controlled. It can actually get worse. If the level of anger goes up you could become even more violent.
It is true that driving under the influence of anger can be just as dangerous as drinking and driving. Driving under the influence of anger is also known as road rage.
