Quad bike deaths focus of new Tas inquest

Tasmanian woman Vicki Mavis Percy, 64, was killed when the all-terrain-vehicle she was riding collided with two motorcycles.

Her 2014 death will be part of a coronial inquest opening in Hobart on Tuesday, investigating the deaths of seven quad bike riders across the island state during a three-year period ending in December 2015.

Coroner Simon Cooper is expected to spend nine days looking into the deaths of Ms Percy, Jay Randall Forsyth, Kendall Russell Bonney, Heather Dawn Richardson, Jan Severin Jensen, Roger Maxwell Larner and Jacob Graham Green.

Shortly after Ms Percy's death in the state's northwest, police said two motorcyclists had tried to overtake the turning ATV at the time of the crash.
