ATLANTA, Nov. 22, 2016 /PRNewswire/ -- The Sunday after Thanksgiving is traditionally one of the busiest travel days of the year and one that sees a dramatic rise in the amount of accidents on our roadways. To remind Americans about the importance of driving safely, Road Safe America (RSA), a non-profit dedicated to reducing collisions between tractor-trailers and passenger vehicles, is encouraging all motorists to observe Drive Safer Sunday on November 27. U.S. Senators Johnny Isakson, R- Ga., and David Perdue, R- Ga. were joined by Sen. Chris Coons, D- Del., in introducing a Drive Safer Sunday resolution in the Senate which passed on November 18th. The observance, now in its 12 th year, is championed by Steve Owings and his wife, Susan, who founded RSA in 2003 after their son, Cullum, was killed when his car - stopped in an interstate traffic jam - was crushed from behind by a speeding tractor-trailer on cruise control going well above the posted speed limit.¿The crash occurred on the Sunday after Thanksgiving in 2002 as Cullum returned to college after spending the week at home in Atlanta with his family and friends. "The Sunday after Thanksgiving will always be a painful day for our family," said Steve Owings. "We hope that by raising awareness of the dangers of holiday travel, many lives will be spared and other families will not have to deal with needless, tragic loss." Each year, more than 1,000 people are killed and nearly 25,000 people are injured in accidents involving speeding tractor trailers. And while the biggest tractor-trailers only account for one percent of vehicles on American roads, they are involved in a staggering 18 percent of fatal, multi-vehicle crashes. In fact, the number of crashes involving heavy commercial trucks has increased 44 percent since 2009.
