ROCKLAND, Maine — A Knox County jury deliberated several hours over two days before agreeing that a Rockport man should be awarded $155,320 for injuries suffered when his motorcycle struck a trailer being hauled by a truck that turned in front of him.

The nine-member jury unanimously voted Thursday afternoon to award Anthony Johnson the damages.

Johnson had sued George C. Hall & Sons and James Hall of Owls Head over the crash that occurred the afternoon of July 2, 2012, on New County Road in Rockland.

Johnson had been traveling east when an oncoming truck and trailer driven by James Hall turned left across the road in front of the motorcycle to get to Belvidere Lane. Johnson’s bike struck the trailer and he was thrown 185 feet on impact, according to police.

He suffered a back fracture, a knee injury that led to a knee replacement, a right shoulder injury, a concussion and multiple cuts and bruises, according to the civil suit.

The jurors determined that damages totaled $238,950, but subtracted $83,630 for what they considered Johnson’s own negligence. There was some question about how fast Johnson was driving at the time.

Attorney James O’Connell III of Lewiston, who represented Johnson, said his client was happy with the outcome of the trial. He praised the jury for its deliberative consideration in what was a complex case.

“It’s been a long, difficult road for him,” O’Connell said.

The trial lasted nearly four days, which Justice Daniel Billings pointed out after the verdict was unusually long for Knox County cases.

The company and Hall were represented by attorney Jonathan Brogan of Portland.

Brogan said after the verdict that there would not be an appeal. He said insurance would cover the damages.

The crash occurred during heavy rain in the middle of a thunderstorm. Lightning struck a utility pole as Rockland Police Chief Bruce Boucher was standing under it while investigating the accident. He was unharmed.
