Thank you for answering my questions.

Firstly, I'd like to acknowledge the advice that's come from this thread about driver-training.
We aim to please or try to ! Thank you, there are some really excellent people around here.

Just need to include, in that training, some specifics about ice and where, how, why and when it lurks.
We believe in intelligent research and guidance for all areas of Road Safety. The promotion of education, and encouragement of driver / road user responsibility, is very important for individuals achieving better road safety for themselves. Each journey that we undertake, helps us to build up important experiences that we can try to learn from.

Hang on ... you have already said it was 'very cold' there must have been signs of that ?
samandben wrote:
There was soft ice, easily removed from the windscreen just before setting off. As said, weather station records showed Air temperature @ 0 to 2C, and we knew that it was cold outside. I aim to find out if there were any media-warnings to drivers prior to the journey. My wife (passenger) said that there were no indications of icy conditions during the journey.
But we have established that there were indications they were just not considered. Equally if there are media or other notifications, unless they are well known about, and people actually refer to them, there is no point to them existing !

She's frightened about car travel (since being in our car which was knocked into a ditch on the M1) and insists that she would have called a halt to the journey had she have been concerned.
It is only the responsibility of the driver to assess a road and conditions, if a passenger observers something, then they should of course inform the driver, for them to deal with it appropriately. There are many things that can be done to help scared passengers (for another topic).
Did your daughter check any of the weather stations or the media, for any updates that you mentioned earlier ?

Have you got a precise location so that we can ascertain the location more precisely please (through Google Earth etc) ?

Well she doesn't sound like she was on ice then .... on ice/ Unable to turn the wheel, generally means that the car has friction i.e. tarmac not ice

Agree. Been trying to figure out what snatched the wheel away. Police-report said black-ice caused the accident. I reckon that the car hit melted ice+surface water first..... gained grip, lost grip. The front wheels went their own way (left) and induced the counter-clockwise spin due to car momentum. Or, she did react initially turning into the skid at it's start, and the tyres gripped through molten ice..........all conjecture from me
Usually to dig through the ice the wheels will have to be in the same position for some moments (eg spinning wheels) - she may have also aquaplaned first or gone over ice first then as the car was re-gripping she unable then to control it. She might also have hit the throttle and gone into a secondary skid, hard to know with out more info - but she may not remember well or enough or even not recall clearly .... many people cannot believe what they may have done but skidding has fairly specific 'routes' but the more info know the better diagnosis. Sometimes the initial cause is mechanical too so it can get very involved.

OR if she cam OFF TOO suddenly that to (with some steering on - corner mentioned) can cause a skid too..

oversteer - & Lift off oversteer - see above.

Can she recall if this was like being driven - going quickly ? was the 'whole' process a slowing process or all 'at speed'?

Just describes it as a smooth, round and round sensation
So she span several times ?
safespeedv2 wrote:
Which verge did she go off - the inside of the bend or the outside of the bend ? Which was R or L bend ?
samandsam wrote:
Ran backwards down the nearside/ left verge. The inside of the bend.
Does she recall if the front of the car went onto the leftside verge first and then the rear of the car swung around onto the verge and then she proceeded going backwards down (what was) her near side verge. (The near side being the passenger side of the car and the driver's side being the off-side.)
(the nearside being nearest to the curb.)

If a major route was it a trunk route ?

'Detrunked' in 2002. Major A road
Ah right OK - major trunk routes are typically gritted as a priority.
safespeedv2 wrote:
Seems strange if only gritted the day before esp for a major A road.
samandben wrote:
Why is that strange, please?
Because all major trunk routes are gritted more frequently - varies of course but I would suspect in very icy conditions every 6 hrs or so depending on the ice state, but the aim is to keep major trunk roads clear of ice - for all emergency vehicles ...

If there is a drop in temperature then mist forms and potential ice.
samandben wrote:
Is this documented, please? If yes can you refer me, please?
Well
MIST (
HERE) but in principal, warmed air meets colder air, so droplets form and fall causing mist or rain (etc eg hail) but if fine and land on shrubbery = mist and frost if weather gets colder and icy ..., then if in a local area only then in shaded areas of road ways or bridges etc., etc ...

This, for me, is the most important issue. Is it passed on formally, eg which section of the Highway Code, please? Only my scientific training made me aware of the shading effect and then only during my research since thee accident!
Well much is in the highway code - see sections from 226 (Adverse Weather conditions and 229, 230 and 231. or
HEREThen you can talk to people who are into learning more about driving, read some of the many books on how to drive better and better car control. Go on courses to learn how to recognise conditions that may become a problem etc .....

Yes, that sort of speed, without incident, for 20+ miles, but completely inappropriate for that isolated, extraordinary stretch of perhaps 300 metres. As above, IMO, we're back at the crux of this subject. Sorry for being pedantic, but could you point me at the part(s) of the Highway Code which warns / advises about such micro-environments, please?
We are happy to analyse that is fine. But the point here is that there might from what you write that just because some method of driving is OK for 20 miles that when 'something' comes up you want a marker or something to *tell you* there is a problem, but there was never a time in that trip where the driver should never stop *thinking* about ice and any localised road condition problems. To always be prepared for changes and always ready for different problems during every mile traveled will
help to keep us safer. There are no guarantees, we have to do everything we can to be as aware and capable as possible, ensuring good attitude and excellent observations, NONE of us are perfect and we are all still learning.
