The small appears to be blaming the black car but it’s the white car that attempts to overtake the van obviously without looking in the mirrors hitting the black car and causing the crash, whose fault was it?
No I can't see the speedo, but from the video it looks as if the camera car was near the 60 limit and the black car came past like a bat out of hell, way over the speed limit. I have been driving for 45 years without an accident, in the Uk and Saudi Arabia. I can judge speed from the video .Look at how fast the camera car is passing the white painted road lane markers it is a good indication of the speed. As it is a single carriageway road the limit will be 60mph maximum .
It doesn't really matter what speed the black car is doing, that's a matter for the police. It is difficult to tell if the white car indicated, but it's obvious the driver didn't use their mirror or look over their shoulder. Hope they have to be retested.
I have driven for 47 years, have my Boy Scouts estimating badge, have given co-ordinates and range for air support to our troops, and haven't got a clue to the speed of the black car. So, well done Eddie.
If you look at my first answer I said BOTH cars are at fault! I still stick with that.
The white car pulled out into the path of the black car , but the black car was so far over the speed limit that the white car driver may have thought it was a lot further back than it really was and they had time to pass safely.
If the black car were speeding the fact that he was breaking the law does not make him liable for the accident. Just supposing I have a mechanically-perfectly car from an MoT point of view but the MoT is 1 day overdue. If you pull out of a junction without looking and I run into you am I at fault? I don't think so.
