A 55-year-old Hughson woman sustained major injuries in a Monday morning crash between her passenger car and a milk tanker truck at Keyes and Geer roads.

The crash occurred at approximately 10:35 a.m.

Hughson Fire Department personnel worked about an hour to free Maria Alay, 55, from the wreckage of her 1993 Honda which was going northbound on Geer Road at the time of the crash. When she was freed she was rushed by MediFlight to Memorial Medical Center in Modesto.

Investigating officers from the California Highway Patrol said that Alay approached the intersection of Keyes and Geer roads at 55 miles per hour and went through a red light. She struck an eastbound tractor-trailer rig pulling a trailer loaded with milk. The truck driver, Jonathan Calderon, 27, of Turlock, was traveling at approximately 50 miles per hour when he saw Alay’s Honda and veered sharply to the left. The front of the tractor struck the right side of the Honda and overturned onto Keyes Road east of Geer Road. The Honda came to rest in the eastbound lane of Keyes Road.

Calderon was able to crawl out of a window of the semi immediately following the crash. An unknown amount of milk leaked from the trailer.

Keyes Road was shut down for approximately five hours between Geer and Berkeley roads so personnel could upright the semi-truck and clean up the spilled milk.

Alcohol was not believed to be a factor in this collision and no prosecution will be sought.
