A、The growing number of motor vehicles doesn’t mean more traffic crashes. B、All countries surveyed have great progress in preven

Road traffic crashes kill 1.25 million people each year worldwide. But the World Health Organization (WHO) says they are preventable.
    The report surveyed 180 countries, and it shows the number of annual deaths from traffic crashes is stabilizing. And that is good news as the number of motor vehicles grows worldwide.
    But the data also show that road crashes are the No. 1 cause of death among young people aged 15 to 29. Young adults around the world are the worst driving risks. Even in the U.S., drivers aged 15 to 24 account for about 30 percent of all driving-related accidents.
    The WHO report also finds a big gap in road safety and deaths between poor and rich countries. Poor countries have only 54 percent of the world’s vehicles. But those countries have some of the worst safety statistics in the report.
    "Africa has only two percent of the world’s vehicles, but has the highest death rate on the road." That is what Etienne Krug, the head of the WHO Department of Non-communicable Diseases, says. Sweden, the Netherlands and the United Kingdom are leaders in preventing traffic deaths. The highest death rates are in Africa and the Middle East.
