UPDATE: 4-Car Crash on Foothill Sends Two People to Hospital

Two people were transported to the hospital Friday with injuries from a three-car collision that stopped traffic on Foothill Boulevard.

The collision at 727 West Foothill, which was reported just after 4:30 p.m., happened when a car struck another from behind as it was attempting to turn, Monrovia Police Lt. Nels Ortlund said.

"That collision began a chain reaction," Ortlund said.

The car that was hit barreled into oncoming traffic, where it collided with another car. That car then hit another, bringing the total cars involved to four.

There was no indication that any driver was under the influence of alcohol, Ortlund said. The initial collision may have been caused because one of the driver's vision was disrupted, he said.

"It appears as though there’s a possibility of the strong glare of the sun…got in their eyes," Ortlund said.

Two people were transported to Arcadia Methodist hospital as a result of the collision. They complained of neck and back injuries, Ortlund said.

Shattered glass was scattered throughout the street and a black sedan remained at the scene with significant damage to the rear end of the vehicle just after 5 p.m.
