A man with a gunshot wound who appeared to be driving to a hospital or clinic passed out behind the wheel of his car Tuesday morning, crashing into a school bus full of students, Texas authorities said.

Harris County Sheriff Ed Gonzalez said they responded to a crash involving a Spring Independent School District school bus before 7:30 a.m. near Rolling Creek.

He said the 10 students and driver aboard the bus at the time of the crash were uninjured. They were moved to a different bus and taken to Spring Early College Academy, according to Click 2 Houston.

The driver of the white BMW sedan had a gunshot wound that authorities believe was sustained during an altercation inside an apartment complex nearby.

Gonzalez said the driver, who has not been identified, was driving away from the apartment when he passed out and slammed into the left-front tire of the school bus.

He was taken to a nearby hospital in stable condition and is expected to survive.
