A mother and her three young children were transported to the hospital after the SUV in which they were traveling rolled into a ditch near the intersection of Old Hardin Road and Calamity Jane Boulevard.
According to Montana Highway Patrol Trooper Justin Moran, the wreck occurred at about 10 p.m. on Saturday as the woman was traveling northbound on Calamity Jane Boulevard and "failed to negotiate a turn in the road."
She overcorrected to the left, into the southbound lane, then to right, back into the northbound lane, where the vehicle went off the road and into a ditch, rolling onto its top.
Emergency crews responded with two ambulances, two Montana Highway Patrol troopers, a sheriff's truck and a Lockwood fire engine.
The mother and her three children were transported to St. Vincent Healthcare with what appeared to be non-life-threatening injuries.
Moran said that the children's father, who arrived after the crash, was unable to provide the children's dates of birth, but Moran speculated that none were older than 13.
The road was partially blocked as a wrecker worked to remove the SUV from the ditch.
Alcohol is believed to be a factor, Moran said. But he said it's too early to tell what sort of citation would be given, as the investigation is ongoing.
