2:58 PM PT -- Police tell us the driver of the car was found pinned in his seat under the crushed roof and so was the female passenger. We're told the fire department had to saw off the roof to free them.
We're also told the driver was airlifted across town to UCLA Medical Center. His condition and Kevin's is unknown at this point. We've reached out to Kevin's rep, but no word back yet.
One of Kevin Hart's classic cars ended up in a ditch in the Malibu Hills after veering off the road ... TMZ has learned, and looking at the damage ... it's a miracle he and 2 other people in the vehicle survived.
The accident happened just before 1 AM Sunday on the winding and treacherous Mulholland Highway. Crash scene video, obtained by TMZ, shows Kevin's Plymouth Barracuda deep in a gully about 10 feet off the road.
The car smashed through wooden fencing along the roadside, and you can see the roof was completely crushed by the impact.
Cops have confirmed the vehicle belongs to Kevin, but they tell us he was not driving at the time of the accident. There were 2 other people were in the car, including the driver -- and cops say Kevin and the driver both suffered "major back injuries."
The third person is a woman who did not require hospital treatment. Police say the driver had not been drinking.
Kevin was first out of the vehicle and according to a witness, a member of his security team showed up in an SUV and picked him up. Kevin lives nearby and cops say he went home "to get medical attention." He was eventually treated at a hospital.
Earlier, on Saturday ... Kevin posted a video of himself in his vintage ride, as someone yelled at him for laying down too much rubber on the street as he spun out his tires.
