A baby girl is safe and healthy after she was rescued by Mill Valley (CA) Police and California Highway Patrol from active highway traffic on Saturday afternoon.

According to the CHP, the four-month-old child was being carried by her mother as the two walked into oncoming lanes of traffic along northbound Highway 101 in Marin, ABC7 reports.

Horrified drivers swerved around the pair to avoid a catastrophic crash, and many passers-by called 911 to report the incident.

After a thorough DUI investigation, the mother was arrested on charges of child endangerment and driving under the influence of a drug.
