The final fatal accident victim on Maine roads in 2011 was a 63-year-old woman from Nova Scotia.

Aizih Gao of Halifax was in the back seat of a car driven by her daughter, Xiao Lin Deng, 40, also of Halifax, on Saturday afternoon.

While attempting to pass another vehicle on Interstate 95 in Edinburg, north of Old Town, Deng lost control of the car, which skidded across both northbound lanes and struck a tree off the breakdown lane, according to state police.

Gao died upon arrival at Penobscot Valley Hospital in Lincoln. No one else in the car was injured.

The likely cause of the crash was driving too fast for conditions, according to State Trooper Tucker Bonnevie.
