A driver is hospitalized after he collided with an 18-wheeler.

The accident happened Friday around 11 p.m. on the Katy Freeway near Fry Road.

According to deputies, a man was driving a Lexus on Fry Road when he didn't see a slower moving 18-wheeler preparing to make a turn and slammed into the back end of the truck.

The Lexus driver was flown to Hermann Memorial Hospital in serious condition.
