Two dead in six vehicle M6 crash
Two people have been killed and two more left seriously injured after a
six vehicle crash on the M6 motorway.
Cheshire Police said two articulated lorries and a transit van collided
on the northbound carriageway near junction 19 and Knutsford services.
They smashed through the central reservation colliding with another
articulated lorry, a van and a car.
A police spokeswoman said most of the motorway between junctions 19 and
18 is closed apart from two lanes northbound.
Drivers are warned to expect long tailbacks.
The two people who are seriously injured were taken to Leighton
Hospital, Crewe, while others were treated at the scene.
========================================================================
What a dreadful and tragic accident.

No idea. The upgrading of the A8 near me uses concrete central
barriers though not in the Y shape, just a thick barrier about 1 metre
high. Whether or not this will be on going or just for upgrades to
busy roads time will tell.

Following the fairly recent roadworks, there's new style concrete barriers
on the M1 north of the M1/M6 junction.

Possibly not, there's no certainty that a solid barrier would prevent
crossover accidents. Such accidents still occur in France and in Italy
where such barriers are common.

Mostly it's a safety thing. A solid concrete barrier causes a vehicle to
rebound into the traffic on the same carriageway, more often than not. It
also does not absorb energy from the impact hence vehicles bounced back
into the running lanes still have a lot of KE and carnage occurs on that
side of the motorway as a vehicle bounces and spins into the following
traffic.
Armco and wire rope barriers constrain the vehicle by deforming and
absorbing energy. They actually guide the vehicle was well as stopping it
from crossing the motorway, and they slow the vehicle progressively.
Unfortunately although Armco can constrain a 44 tonne vehicle, it's not so
hot at stopping two of them.

There's a section of the M25, near the M1, with them as well.

The big concrete ones? What happens when a vehicle goes across? Does it
smash the concrete or does it jump over?
I've seen the semi-circular tyre marks on the French ones where a
vehicle hits the barrier, goes up, and then down...

Thanks. I don't quite understand what you mean by that. Would you just
expand a wee bit?

I've seen both, large vehicles can smash right through. The barrier isn't
as solid as it looks. The important feature is the foot of the barrier. The
inverted Y shape is supposed to steer the front wheels of the vehicle and
constrain it to remain on the same carriageway or at least to strike the
barrier a glancing blow rather than 90 degrees.
I've also seen vehicles that have hopped over the barrier. I think that
this happens most often when on the motorway causes the front
end to lift, such as hitting a vehicle that is already stationary, or
hitting street furniture.
