A "car crash" is a particular kind of accident: a violent collision in which a car has slammed into something, or something (such as another vehicle) has slammed into it, usually at high speed, with considerable damage and/or injury resulting.
A Tustin car crash that occurred on Monday, March 21, 2011, involved a pedestrian and an elderly driver from Aliso Viejo. According to reports, the accident occurred during heavy rains just prior to noon at Red Hill Avenue and Interstate 5.
The pedestrian was killed in this crash, as she was dragged for over half a mile. She was hit at Red Hill Ave., but her body was dragged to Newport and Walnut Avenue, where, according to police, it became dislodged from the vehicle.
Yes, NTV, perhaps....and resulting in death, perhaps?
In AE, a collision between a motor vehicle and another vehicle, a pedestrian, or a fixed object such as a tree or telephone pole used to be (1960's and probably later) referred to universally as an "accident." However, some vehicle-safety activists objected that, especially when the driver was under the influence of alcohol or driving faster than the speed limit, such incidents were not accidental, but the foreseeable results of deliberate decisions to do drugs, drink too much, drink at all, drive too fast, etc. They crusaded for replacement of the word "accident" to describe such incidents, and the word became politically incorrect. Therefore, politically correct news media now use the word "crash" to describe what used to be called an "accident."
