According to Harris County Sheriff Ed Gonzalez, one vehicle was jumpstarting another in the middle of the roadway on Sralla Road at FM-1942 when a third vehicle struck them.
One person was taken to the hospital via Life Flight in critical condition and a second person was transported by ambulance in stable condition, Gonzalez said.
SkyEye video from above the scene showed two damaged vehicles in a ditch along the roadway, and a pickup truck with front-end damage nearby.
Gonzalez said the intersection would likely be closed for several hours.
