OLYMPIA — AAA warns teens to be careful on the road heading into summer, the deadliest season for young drivers, although local officials say teen traffic deaths are on the decline. Seven of the top 10 deadliest days of the year for teen drivers and passengers nationwide fall between May and August, a AAA report said. June 10 is among those days, and five of the other days are next month: July 2, 4, 9, 15 and 23. AAA reports that more than 7,300 teens died in auto accidents between the Memorial Day and Labor Day holidays from 2005 to 2009.Yet in Clark County, teen traffic fatalities are fairly rare. Five teens died in traffic accidents in Clark County between the Memorial Day and Labor Day holidays from 2005 to 2009, said Kristal Rust, a research analyst for the Washington Traffic Safety Commission. In total, 12 teens died in Clark County from traffic crashes during those five years. Those numbers do not include the four Ridgefield teens killed in an August 2009 crash near Clatskanie, Ore.Throughout the state, 105 teens died in traffic accidents between the Memorial Day and Labor Day holidays in that five-year span, accounting for 34 percent of teen traffic deaths in the state for those years.“Because the number of teen driver and passenger deaths in Clark County is relatively small, the monthly average is less than one (teen death),” Rust said.
