The impact ripped the wing mirror off the truck and left Ashill with severe injuries - including a smashed pelvis, compound fracture to his right femur and bowel perforation.
He was on a Skype conversation with his wife Sarah when he was struck.
This week, speaking from her husband's hospital room in Columbus, Ohio, Sarah Ashill told the Weekend Herald how what started as a normal day quickly took a tragic turn - leaving Nick fighting for his life, bleeding heavily in a ditch and unable to move.

Sarah Ashill was in Cyprus at the time with the two youngest of the couple's four daughters.
"It was like the movies. I saw just the rolling of the grass," she said.
"I was like 'what's happening'. It went silent and then he yelled. When I heard that yell I knew that something was seriously wrong."
Ashill remains in hospital and his wife said his medical bills had already totalled more than $500,000.
That figure was set to increase during his rehabilitation.
