VISTA–An off-duty deputy sheriff on his way to work Monday was involved in a traffic collision in Vista, Sheriff’s department reports.

The incident occurred just after 5 p.m. at the intersection of East Vista Way and Arcadia Avenue. The driver of a Chevy Cobalt driving westbound on Arcadia Avenue ran a stale red light while making a left turn, causing the collision with the deputy who was travelling southbound through the intersection. The impact caused the deputy’s Ford truck to careen into a block wall at an adjacent mobile home park. Both drivers were transported to Palomar Hospital with moderate to serious injuries.

Witnesses said the other driver suddenly entered the intersection into the path of the deputy’s vehicle. Alcohol was not a factor in this collision.
