51 cars involved and 10 deaths. But the original cause was a driver falling asleep and a large contributing factor to that was fog. So again it wasn't speed that was to blame but tiredness and inappropriate speed for the conditions. The reports said that the cars were travelling at 70mph so none of them were speeding but they were driving too fast for the conditions.
I hate quoting wikipedia but this was the first report I came to.....
"On 13 March 1991, a multiple-vehicle collision occurred during foggy conditions on the eastbound carriageway of the M4 motorway near Hungerford, Berkshire, between the Membury service station and junction 14.Ten people were killed in the pile-up, which involved 51 vehicles, making it one of the deadliest crashes in the history of Britain's motorway network.
[h=2]At 2:15 p.m. on 13 March 1991, a driver fell asleep at the wheel of his van and skidded into the central reservation. A car travelling behind the van changed lanes to avoid contact but other vehicles behind, which were travelling at speeds averaging 70 miles per hour, failed to avoid the crashed van and skidded into the other lanes of the carriageway. Others took evasive action by driving onto the hard shoulder and up the sides of the cutting. An articulated lorry then jack-knifed across all three lanes of the eastbound carriageway". [/h]
it was more in response to everyone travelling in the same direction and on fairly straight roads
And yes it happened at the speed limit - imagine if the cars were travelling faster - possibly more deaths.
Some people also made some awful choices whilst it was going on.
