DENISON, Texas (KXII) -- A head on collision in Denison sent nine people to the hospital, one with serious injuries.
The head-on collision was on Highway 75 and Loy Lake at around 11 a.m. Saturday.
"the vehicle that was Northbound on 75, and for some unknown reason as of yet, it crossed the median and struck head on with a South bound vehicle."
Lt. Mike Eppler with Denison Police says the collision caused two more cars to get into an accident.
One of them, a mini van, drove off the highway..down an embankment and rolled, hitting the back of another van driven by Denison City Manager Judson Rex.
He and his family were not hurt.
"A green van that was hit on the main lanes rolled down off of 75 just nicked our van and we were very fortunate that we didn't get hurt."
Nine people were taken to the hospital including an infant.
Police say all have minor injuries except one passenger from the car that veered into the South bound lanes.
That person was taken to the hospital in serious condition.
A helicopter was requested but canceled due to weather.
Sherman first responders assisted Denison with the accident.
"Lots of EMTs and ambulances and folks being pulled out of cars. Looked like a pretty bad accident."
Rexx says he and his family are still in shock that they didn't get in a serious accident.
"I'm not even sure what I did. I kind of swerved off because we saw the green van come off the hill and just swerved off the road to miss it."
The cause of the accident is under investigation.
