Truck drags driver trapped in car down California highway

A man traveling along a California freeway captured the shocking moment a car that was wedged onto the back of a big rig was dragged miles down the road.
Brian Steimke was driving down I-15 freeway on Wednesday afternoon when he witnessed the burgundy Nissan Maxima stuck under the truck.
As Steimke gets closer to the car, he notices the driver waving his hand out of the window in an attempt to get the truck driver's attention.
'He's not stopping,' the driver of the car shouted to Steimke.
The video, which was uploaded to Facebook, showed major damage to the passenger side of the car.
The windshield was also destroyed and the airbags had deployed as smoke spewed from the car while it was being dragged down the freeway.
As Steimke drives up and pulls over, another car could be seen braking in front of the truck, forcing him to stop.
Steimke then gets out of his vehicle and walks up to the truck driver.
'Why were you driving so far?' Steimke asked the man, who hasn't been identified.
The truck driver asked, 'so far?' not seeming to realize he was dragging the car for several miles.
Steimke explained to the man that the guy was wedged on the back of his truck, to which the truck driver responded: 'I didn't know.'
'What do you mean you didn't know it dude?' a surprised Steimke asked. 'He's on your truck!'
Steimke told the trucker that he needed to get out of the big rig before walking to check on the driver of the Nissan.
The badly damaged vehicle was propped against the rear tire of the truck.
It's unclear how the car managed to get wedged under the big rig and the driver of the Nissan hasn't been identified.
