The county’s traffic deaths in 2014 were twice as high as they were in 2013, and higher than any other year in the last decade. The increase in traffic fatalities also bucks the statewide trend, in which the number of deaths has stayed more or less flat in recent years, said Staci Hoff, director of research at the Washington Traffic Safety Commission.“There’s nothing out there that says why all of a sudden we took that jump,” said Marion Swendson, manager of Clark County’s Target Zero program, a statewide effort to eliminate all traffic deaths and serious-injury crashes by 2030.Last year’s fatal crashes happened for a variety of reasons, whether it was speed, a driver mistake, the driver having a medical problem or — the top cause — driving under the influence. For years motorists under the influence of drugs or alcohol have been the leading cause of local traffic deaths. In 2014, they accounted for at least 14 lives lost. Allegedly, two drivers in those cases were under the influence of pot, some had taken other drugs and most had been drinking.
