Somerset police say Vickie Maynard of Russell Springs may have hit a guardrail Sunday morning on Kentucky 80 Bypass before stopping on the side of the road.
Frank Adams, Jr. saw Maynard on the side of the road and stopped to help.
He says Maynard claimed a bomb was in her truck and accused him of taking her baby.
Later, Dawna Wade also pulled over to help.
Maynard eventually got into Wade's truck to keep warm.
When the police pulled up, they say Maynard put the truck into drive and pulled off, striking Wade.
Somerset police say they chased Maynard for a short time. When she pulled over, she drove off again, continuing the chase for another 4 or 5 miles through Somerset.
Police say she was eventually taken into custody without incident.
Wade was taken to a hospital for her injuries and later released.
A bomb was never found in Maynard's vehicle.
