SAN ANTONIO -

Police said lack of sleep and alcohol contributed to three separate accidents on the roads early Friday morning.

The first crash occurred around 2:30 a.m. after a woman in her 30s said she fell asleep at the wheel. 

She struck a guardrail and rolled her vehicle onto the access road of Interstate 35 near Division. She was taken to the hospital with minor injuries. There was no word if she would be ticketed. 

Around the same time, a man in his 30s driving on the access road of Interstate 10 near The Dominion had to be cut out of his pickup truck after he crashed into a barrier. 

Police say the driver tried to take the entrance ramp, but missed and struck the barrier. The impact ripped a tire off his truck and caused it to flip on its side.

The driver had to be cut out of the truck and was taken to University Hospital in unknown condition. Police said he is suspected of driving while intoxicated. Two weapons were also found in the truck, but it was not clear if he had a permit for them. 

About 30 minutes later, police responded to the another accident on the Northwest Side at Interstate 10 and DeZavala Road. 

Police say a woman in her 20s was headed east on the highway when she struck the barricade after exiting DeZavala.

The impact of the crash knocked over the barricade and her truck landed on top. Police said she is facing DWI charges.
