What a lucky escape...the wooden post could have driven through her body

Massachusetts State Police shared this photo on Facebook on November 4, showing how a woman escaped injury when a wooden post flew through her windshield. The post reads:

This morning, just after 11:00 a.m., a 67-year-old woman from Holyoke was traveling north on Interstate 91 in Springfield when a 4x4 wood post came through her windshield. The wood post is believed to have fallen off off of another vehicle.
It was then run over by a tractor-trailer, sending it through the air and into the Subaru windshield. We are thankful the woman was not injured, but would like to remind all motorists to ensure all loads are properly secured. This incident could have had a fatal outcome.
