Not sure about that. Please detail what those indications were.
The fact that is was cold and icy enough for her to have to clear her windscreen, and that location was in an urban area, she then traveled out of town. Urban areas are always 'warmer' so by traveling out into the more rural areas it is 'known' that there will be a drop in temperature and pockets of potentially very cold / freezing areas e.g. especially one's that are in the shade and do not receive much or any direct sunshine, that helps to warm up the ground and air temperature. She could probably 'see' her breath in the air, which is also an indicator that it is very cold.

It is only the responsibility of the driver to assess a road and conditions

IMHO, there are innate and subliminal senses of responsibility and awareness in the majority of drivers. Certainly, my Daughter is responsible, and her driving record suggests a good state of awareness. However, isn't it the relative level of sensibility that's the most important aspect?
I was referring to the thought that the passenger (your wife) might influence the driver to the point of canceling the trip - I appreciate that you see this as that the passenger 'felt' safe but she was not receiving much feed back from the car controls. The driver is far better placed to make these judgments more accurately.
The Lizard Brain mentality is a fascinating area of people's behaviour - the survival instincts and learned 'innate' behaviours in our more modern world.
Responsibility is something that can be coupled with good attitude, good attitude tells us that we can always, do and learn better, so that our abilities and skills can be improved. I was not specifically saying anything about your daughter, it is principals that we are exploring here.

Did your daughter check any of the weather stations or the media, for any updates that you mentioned earlier ?
samandben wrote:
I need to ask her.
My point here is that whilst we can check the weather it is rare that we all go to the trouble of check more precise data. I have called the gritting 'office' to find which roads they have gritted and when, to know how much time I may need to allow for my journey (allowing to travel very slowly), as well as keeping a very close eye on the weather on TV and online to also give me all the info that I can 'normally' find.

Have done this. [quote"samandben"]How will that help you, please?[/quote]
Well the more info that we can 'see' the better we can see what might be done, by engineering the road better to the specific bend, where the ice might have been. The road warnings that might be 'there' but not observed, e.g. hedges that might have frosted grass on one bank that is in the sun's shade. Overall to help ascertain where if any, improvements might be required and to try to understand the accident processes. If you are not happy with this then I totally respect that decision.

Does she recall if the front of the car went onto the leftside verge first
samandben wrote:
Wife confirms that first the car span anticlockwise into the other lane then returned, smoothly spinning, to the correct lane. Finally meeting the nearside verge, correct side, going backwards until the collision.
After the first 'spin' that took them onto the oncoming lane was the second set of spinning, in a clockwise direction ? She didn't hit the opposite roadside verge ?

...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
samandben wrote:
Every 6 hours? Can you tell me where that info comes from, please?
This is just my experience (and calls to local authorities) in my local area, but the routes are so long up here by the time they have gone one way they need to go back and start again and especially, if they are also removing snow, a little quicker if they are 'just gritting' but then they travel down more roads on a set priority rota. You can call and ask your local authority which are the priority routes, they are usually the one's to important locations eg Hospitals / Emergency Services / MOD etc ... then schools, and so on ...

But that morning was cold enough for some indicators (windscreen ice, in urban area), that there night be a problem ...? Then every shaded area, bridge, 'open countryside' areas, tree covered roads, shaded road sections, farm entrances, curved up/down hill bends (water goes across at angle), corner (slow in 'fast' out to ensure good obs during approach and whilst apexing bend for confirmed 'clear road' driving conditions). All these points and more need to be considered on every drive, in summer for mud, loose grit, damp patches, and in winter, damp leafy, icy conditions ...

Mmmm, compare the lack of descriptiveness in their ..'be prepared for the road conditions to change over relatively short distances' ...and.....'Drive extremely carefully when the roads are icy.

http://www.iam.org.uk/pressroom/driving ... ngtip1.htm) Yet neither source educates the reader about the fact that Black Ice is likely to be invisible. Or how to recognise it when it's not. Isn't that an encouragement to try to decide when to continue taking a risk?
Well the HC is being overall specific as a rule and the IAM are being 'informative'.
Are you saying that people are unaware that Black Ice is 'black' / invisible ? Surely we have all stepped onto ice we hadn't 'seen' at some point in our lives ? Surely we know ice is not always easy to see? The HC is trying to say go carefully, they cannot possibly ever be, so specific that they can describe every circumstance, can they? So they select words the cover and overall rule to give good advice, and every word 'counts'. What do you not think that it covers?
The IAM article didn't say it was black/invisible ... just "Black ice occurs in patches, so it is very easy to be lulled into a false sense of security after driving for some miles along a road that seems normal."
IAM link.Do you prefer this because it is a little more descriptive?

I applaud.............. 'DO NOT drive in these conditions unless your journey is essential' . That is now precisely the advice I am giving to nearest and dearest.
For sure I will travel less and many do if the roads are potentially icy and then I'll travel at the best times that I can (chk grit lorry times and routes etc) to try to always ensure that I keep myself safe. I cannot say that I have ever got enough experience to always cope with every scenario, but I try to give myself the best experiences that I can, use caution and obtain the best skills possible and I am always on the look out to learn more. I do analyse things though and will do so, thoroughly before I might decide to add that snippet or advice into my 'Driver's Toolkit' of skills and knowledge.
