A 26-year-old woman was killed in Halifax early Saturday morning after her SUV struck a tree, according to the Halifax Fire Department.

Caitlin Ledwell of Halifax was driving her 2011 Nissan Rogue about 100 miles per hour on South Street, before it ran off the road and struck a tree about 2 feet in diameter, said Fire Chief William Carrico.

When officials arrived at about 12:22 a.m., residents had pulled the victim from the wreckage. She was taken to Brockton Hospital, where she died, Carrico said.

The impact of the crash “split the car in half,” he said. “[The tree] was between the passenger’s and driver’s seats, one of the wheels was about 100 feet up the road, and the car exploded.”

Carrico said the road had been “in pretty bad condition” until recently, which prevented drivers from speeding.

But the surface was recently paved, and Carrico said he expected the number of accidents on the road to increase.

The road is mostly straight, except for a slight curve, Carrico said. “That’s where she wiped out,” he said.
