A 2-year-old was thrown from a vehicle during a traffic crash on Interstate 12 near Essen Lane at 8:50 a.m. Monday, authorities said.

Seven others, four of whom were children, also were injured in the crash, East Baton Rouge Parish Emergency Medical Services spokesman Mike Chustz said. All eight were taken to medical facilities for treatment.

One of the children was in critical condition, another was in very serious condition and the two others were in stable condition, Chustz said. All four adults were in stable condition.

Baton Rouge Police Department spokesman Sgt. Don Stone said three vehicles were involved in the crash.

The vehicle holding the children was traveling north on the Essen Lane entrance ramp to I-12 when the vehicle failed to maneuver a curve, crossed a grassy area and hit two vehicles traveling east on I-12, Stone said.

It is unclear whether the children were restrained, Stone said. Investigators with the Police Department’s Traffic Homicide Division are investigating the crash.
