Sgt. Sean Kelley says Lewis was a passenger in the back seat of a four-door sedan Wednesday night when a driver ran a stoplight, smashed into Lewis' vehicle and kept going.
The car was found a short distance away, but the driver had fled the scene.
Kelley says Lewis complained of pain in her head, back and neck and some bruising and was taken to a hospital.
He says the driver will be arrested on suspicion of felony hit and run when found.
The 37-year-old Lewis received a best supporting actress Oscar nomination for her role in the 1991 film "Cape Fear."
She appears in the soon-to-be released film "Conviction."
