An investigation into the November 2010 death of bicyclist Lauren Perdriau Ward, who died in a collision with a big rig on Alpine Road, determined that the bicycle was hit from the rear and was upright during the collision, the California Highway Patrol announced Thursday.
Ward, 47, a Los Altos Hills resident, was riding west near Portola Valley at Interstate 280 when she was hit by a 26-wheeler and trapped beneath the vehicle, according to the CHP.
The CHP has determined the bicycle came into contact with the left front portion of the truck, which collided with the right rear portion of the bicycle, while the bike was still in an upright position, based on additional forensic testing and a subsequent accident reconstruction.
But investigators could not determine the relationship of both vehicles immediately preceding the collision and did not have enough information to determine whether Ward or the big-rig driver was most at fault, the CHP said.
Ward, a trained nurse, won state Sen. Joe Simitian's "There Oughta Be a Law" contest after suggesting a bill to add a bittering agent to antifreeze so that children and animals would not be accidentally poisoned.
