The violent crash happened in the 9400 block of Homestead Road at Tidwell.
Investigators said two officers were headed east on Tidwell with their lights and sirens on when the vehicle careened into the cruiser.
The patrol vehicle spun several times, striking three other cars.
Traffic cameras caught the moment officers began escorting an ambulance carrying the injured cop to the hospital.
John Cannon with HPD says the officer was transported with "non-life threatening injuries."
The passenger and driver of the other vehicle were taken to Memorial Hermann Hospital, also with non-life threatening injuries.
Police said alcohol does not seem to be a factor.
