The World Health Organization announced that car crashes are the leading cause of death worldwide for people between 10 and 24, adding that most such fatalities occur in developing countries with poor road safety conditions.

“The lack of safety on our roads has become an important obstacle to health and development,” said WHO’s director-general, Dr. Margaret Chan. “Our children and young adults are among the most vulnerable.”

“Road traffic crashes are not ‘accidents,'” Chan said. “We need to challenge the notion that they are unavoidable.”
