A woman who drove into an intersection on a red light was struck by a milk tanker and sustained major injuries, the California Highway Patrol reported.

The collision happened around 10:30 a.m. Monday at the intersection of Geer and Keyes roads.

Maria Alay, 55, of Hughson was driving a 1993 Honda northbound on Geer Road. As she approached the intersection with Keyes Road the traffic signal for Geer traffic turned red, but Alay continued into the intersection, according to the CHP.

A 2016 Western semi-truck hauling a milk tanker driven by Jonathan Calderon, 27, of Turlock was traveling eastbound on Keyes Road.

Calderon saw the Honda enter the intersection and made an attempt to avoid striking it by veering the semi-truck sharply to the left, the CHP reported.

The front of the semi-truck struck the right of the Honda and overturned onto its side.

The Honda came to rest in the eastbound lane of Keyes Road. The damage to the Honda was significant and Alay was pinned inside it for approximately an hour. She sustained major injuries from the collision and was taken to Memorial Medical Center.

Calderon crawled out the window of the semi-truck and said he would seek his own medical aid. 

Between the overturned tanker and the spilled milk, Keyes Road was closed for about five hours, according to the CHP.

Alcohol and drugs were not considered to be factors in the collision.
