| The Sheppey Crossing pile-up involved 130 vehicles colliding in thick fog at high speed. Even worse, the crash took place on a bridge with no hard shoulder. Some commentators have said it was a miracle that no-one died. | The Sheppey Crossing pile-up involved 130 vehicles colliding in thick fog at high speed.

| The vehicles were travelling fast. The speed limit was 70mph for this dual carriageway bridge, higher even than bridges that are wider. The Dartford Crossing is four lanes rather than dual carriageway yet the speed limit is only 50mph. | |

| After the Sheppey accident, Kent Police's Assistant Chief Constable Rob Price said it was "a miracle" there were no life-threatening injuries. It is too early to say how no-one died, a police spokesman says. | After the Sheppey accident, Kent Police's Assistant Chief Constable Rob Price said it was "a miracle" there were no life-threatening injuries.

| One of the key factors in fatalities is whether there are heavy goods vehicles (HGV) that cannot stop in time, says Edmund King, president of the AA. After the Bromsgrove crash an HGV driver was convicted of dangerous driving. The sheer weight of a 44-tonne truck gives car passengers little chance when hit at speed. | One of the key factors in fatalities is whether there are heavy goods vehicles (HGV) that cannot stop in time, says Edmund King, president of the AA.

| Motoring journalist Quentin Willson thinks the word miracle is unnecessary. For him it's all about the design. "In the old days if you'd been in a Cortina you would have gone through the windscreen. The engine would have folded." Nowadays the chassis is much tougher and this is unlikely to happen, he says. | Motoring journalist Quentin Willson thinks the word miracle is unnecessary. For him it's all about the design.

| Car manufacturers have improved safety features in relation to this. A safety cage now envelopes the cabin, stopping passengers from being crushed. There are crushable zones around it to take away the energy from the crash. | Car manufacturers have improved safety features in relation to this.

| Previously, drivers would be at risk of having their legs or feet crushed as the cabin would give way and pedals come towards the driver, Avery says. Today that shouldn't happen as the interior will remain intact. | Previously, drivers would be at risk of having their legs or feet crushed as the cabin would give way and pedals come towards the driver, Avery says.

| Seatbelts have load limiters, which give a little, thus reducing the forces on the body at high speed braking. | Seatbelts have load limiters, which give a little, thus reducing the forces on the body at high speed braking. |
| There are more airbags. Side airbags protect the thorax and body. Curtain airbags fill the space where the window is and protect the head. Head restraints go forward to help protect against whiplash. | There are more airbags. Side airbags protect the thorax and body.

| The bridge was probably a contributory factor, increasing the scale of the pile-up, King says. Cars coming up to the apex may not have been able to see the density of the fog on the other side. | The bridge was probably a contributory factor, increasing the scale of the pile-up, King says.

| But the central reservation and side barriers on the bridge "did their job" King says. They prevented vehicles from plunging off the side or into oncoming traffic on the opposite carriageway. | But the central reservation and side barriers on the bridge "did their job" King says.

| In the future, the scale of multiple-vehicle pile ups will be radically cut by technology, Avery believes. At present only 1 or 2% of cars have AEB (autonomous emergency braking) - where the car brakes automatically or warns the driver at the sign of an obstacle ahead. | |
| "It's radar-based so that even when it's foggy it would have worked," he says. And soon it is likely to become a common feature. | "It's radar-based so that even when it's foggy it would have worked," he says. And soon it is likely to become a common feature. |
| Next year cars seeking a five-star safety rating will require AEB features. Also from 2014 it will become mandatory for lorries to be equipped with forward collision warnings. Crashes will still happen but there will be very few big pile-ups, Avery predicts. | Next year cars seeking a five-star safety rating will require AEB features.
