A Georgia judge has denied three of four Ford Motor Co. post-trial motions after a jury last year awarded $1.7 billion in damages against the auto maker, the largest verdict amount in the state’s history.

The lawsuit was filed by Kim and Adam Hill, the adult sons of South Georgia farmers Melvin and Voncile Hill, who died in 2014 when their Ford F-250 rolled over while on the way to Americus to pick up a tractor part when a tire blew out. The sons claimed their parents died because the roof crushed on them in what should have been a survivable accident.
