A distracted driver caused a chain-reaction crash in Chula Vista Saturday that injured four people, including a pre-teen boy.

The male driver of a white truck told Chula Vista police that he became distracted while driving westbound on Orange Avenue just after noon, according to OnScene.TV.

He said he glanced away at a red light and as he looked back up, he slammed into a red Toyota. Four more vehicles that had been stopped at the light were also involved.

A 12-year-old boy in the red car suffered a compound wrist fracture. Authorities sent the victims to local hospitals for treatment.

Officers closed westbound Orange at Melrose Ave for more 90 minutes following the crash.
