Whatever you call it, road rage can be deadly.

The term "road rage" refers to argumentative and sometimes violent behavior by drivers when annoyed by other road users' actions. It is believed to have been coined in the United States in the 1980s, and had spread to the U.K. by the next decade.

While the English "rōdo rēji" is understood by Japanese, the tabloids avoided use of this term in their reports of recent incidents, including a fatal accident on the Tomei Expressway last June 5. They instead have been described in the vernacular with a variety of different words.
