Investigators say a woman in an SUV collided with Deputy Don Maxey at the intersection of Louetta and Kuykendahl.
They believe she was under the influence, but it's not yet clear if that means drugs or alcohol.
Captain Michael Koteras with the Harris County Sheriff's Office said they did find trace amounts of marijuana in her car.
Authorities also say one of the drivers likely ran a red light.
We're told Maxey was in and out of consciousness and appeared to be in a lot of pain.
Authorities say he also appeared to have internal injuries. He was loaded into an ambulance and transported to a local hospital.
He is expected to survive.
Maxey was in his personal vehicle at the time of the crash. He was on his way to work.
