State troopers confirmed they are investigating a serious car wreck on Highway 93 in the Mission Valley.

It happened sometime before five Wednesday.

Troopers say a car pulled out from a side road onto the highway and was hit by another car.

Investigators say the driver of the car that pulled into traffic was ejected and that two children in that same car were injured.

We do not know their conditions. But troopers say neither was in a child seat or was wearing a seat belt.
