A Byron woman and her two sons were taken to the hospital after an ATV crash in Byron on the way to the school bus stop Monday morning, according to the Maine Department of Inland Fisheries & Wildlife. 

Elizabeth Wallace, 42, was taking her 12- and 13-year-old sons to the bus stop just before 7 a.m. on Dingle Hill Road on a 2003 Arctic Cat ATV, the department said. 

“At some point traveling down the steep, paved portion of the road, the ATV veered off the righthand side of the road into a ditch, and the machine flipped, tossing the 12-year-old son to the side of the road, and trapping the mother and 13-year-old son under the ATV,” the department said in a statement. 

The 12-year-old, according to the statement, went down the road and started knocking on doors to get help. The boy found three Massachusetts men renting a cabin nearby who came to help. By then, the 13-year-old had gotten out from under the ATV, but Wallace remained trapped.  

The men moved the ATV and called emergency personnel. 

Wallace, according to the statement, had injuries to her pelvis, back and head, while one boy had a possible back injury and the other had a possible head injury. All three were taken by ambulance to Central Maine Medical Center.  

None of them, the department said, were wearing helmets at the time of the crash.  

The cause remains under investigation.
