St. Charles County, MO (July 17, 2026) – A 26-year-old woman and an infant were hurt in a two-vehicle crash on Interstate 70 westbound east of Zumbehl Road in St. Charles County on Tuesday morning, July 14. The collision was reported at 11:10 a.m.
A 2022 Toyota Camry driven by a 47-year-old St. Louis man merged from lane three into lane two, and the front of a 2021 Honda Pilot driven by the 26-year-old St. Charles woman struck the rear of the Camry. The Camry’s driver was not hurt in the wreck.
The woman sustained moderate injuries and was taken by ambulance to Mercy Hospital St. Louis. An infant riding in the Pilot also sustained minor injuries and was taken to the same hospital by a private vehicle. The accident remains under active review.
We hope both people hurt make full recoveries.
What Happens When an Infant Is Injured in a Highway Crash?
When a very young child is involved in a crash, medical teams prioritize rapid evaluation even when injuries initially appear minor. Infants cannot communicate symptoms the way older patients can, which makes thorough assessment especially important following any collision. Imaging and specialist evaluation are typically used to rule out internal injuries or head trauma that may not be immediately apparent from outward signs.
Age-appropriate restraint systems for infants are designed to distribute crash forces across the strongest parts of a baby’s body, reducing the risk of serious injury in a collision. A rear-facing infant seat, when properly installed and used, provides meaningful protection even in moderate-speed rear-end crashes. Medical teams note the type of restraint used when evaluating a young patient, as it helps them understand what forces the child may have been exposed to.
Lane-change crashes on interstates occur when a driver does not fully clear the adjacent lane before completing a merge. At highway speeds, even a brief overlap between vehicles can result in contact significant enough to cause injury, particularly when one vehicle strikes the rear corner of another. These crashes are reviewed for the following distance, mirror usage, and whether the merging driver signaled before changing lanes.
