LA MESA, Calif. -- Three people were taken to a trauma center Friday morning after two vehicles crashed head-on in La Mesa.
The crash was reported around 10:30 a.m. along the 4200 block of Avocado Boulevard and involved a Cajon Valley School District Ford pickup truck, which was towing a utility trailer, and a 2011 Ford Fusion.
According to the California Highway Patrol, the vehicles were heading in opposite directions when a 55-year-old man driving the pickup made a sudden turn. The movement caused the truck to collide with the Ford Fusion, which was driven by a 23-year-old woman from El Cajon who was traveling with a female infant in a child safety seat.
Video from the scene showed the crash caused both vehicles to travel into a residential yard, causing a tree to topple onto a house.
CHP officials said the child safety seat had not been properly installed, causing the seat to fall facedown on the car's floorboards upon impact.
Officials with San Miguel Fire said all three victims had to be extracted from the vehicles and were taken to a trauma center for treatment of their injuries.
Both drivers suffered major but non-life-threatening injuries, CHP officials said. Details regarding the extent of the infant's injuries were not immediately known.
San Miguel Fire officials said the tree that fell on the house caused minor damage. The homeowner was not at the house at the time of the crash.
Authorities were investigating the cause of the crash and said neither alcohol nor drugs were considered to be a factor.
