Cal State Fullerton's women's soccer coach is pushing for more college sports teams to implement helmet rules for athletes on e-bikes and e-scooters after a box truck hit and seriously injured two of his players who were riding e-scooters in September. Lauren Turner and Ashlyn Gwynn, both sophomores on the soccer team, were riding e-scooters to a men's soccer game around 7 p.m. Saturday, Sept. 27, when a box truck struck them near Associated Road and Yorba Linda Boulevard, police said.
