They asked me that question on my test, it is in the Highway Code which you are tested on when taking a test and which your driving instructor takes you through. You are not expected to know as 'common knowledge', which is the case you are trying to make. You should be a member of PN staff they seem to able to duck and dodge and debate how many angels on a pin head, much better than trying to answer any questions that might be difficult because they relate to PN's poor services.

A dual carriageway by definition has a central reservation.

Correct. A dual carriageway can be anything from 1 to many lanes. The maximum speed limit, unless signed otherwise or a lower limit applies for the type of vehicle, is 60mph.

Note a motorway is not classified as a dual carriageway and special regulations apply. There is (I think) still one single carriageway stretch of motorway.

Strictly it has a central divide, may be little more than a raised kerb. Paint markings are insufficient.

Since when has the speed limit for a Category B vehicle been 60mph on a dual carriageway?

Sorry, my bad. You are quite correct, it's 70mph on dual carriageways and 60 on single carriageways.

It's been a long day...

As a side issue. I knew the single carriageway limit for goods vehicles >7.5 tonnes MLW had gone up to 50mph earlier this month (and to 60 on dual carriageways). I hadn't realised that was only the case in England & Wales. In Scotland it's still 40 on single and 50 on dual. Details here.

That's what I call a reservation . Paint markings do not, by definition, create two carriageways.

Ah, I did get slightly confused by the definition of "dual carriageway". However, in practice I know that if there is a central reservation then national speed restriction is 70mph and if not then it is 60mph. In practice it doesn't matter what you call it as long as you know the limits.

The point is that many people think, wrongly, that it is 60 when in fact it is 70. The driving instructor is NOT required to inform you, it is up to you as a driver to read and keep up to date with the highway code. How many drivers on this forum know the current highway code.

Again - ignorance is no defence. "I'm sorry officer my driving instructor didn't notify me about that" won't wash.

Read your terms and conditions and use a little common sense as it goes a long way.

You are right.

there is no ignorance. The Officer would say that the driving instructor told you that these were the limits and they are set out in the highway code and you would be told that you ne e d to regularly update yourself to keep within the law. I was told that, I was instructed, as to how to stay within the law. But if no one had bothered to tell me there was a Highway Code or that it was ignored now, then I would have to rely on 2common knowledge". Gladly if you are expected to know then you are so instructed. Same at work if you use equipment, you must be instructed in its use and if you are not and you injure yourself, your work is responsible because they have not shown you how to use the equipment. You are now trying to defend the indefensible. PN have to inform you if the re is a possible cost for a service BEFORE they perform it and if they do not inform you BEFORE then you are not liable to pay it. My last post on this offtopic rubbish you keep raising.

But what was really sneaky and unacceptable was that PN did not inform me when booking the appointment, they slipped it into an email sent AFTER the booking but BEFORE the appointment, thereby hoping that I, and others because they do this to others, would not notice.

They say a leopard does not change its spots, I thought that was not true of PN, but it clearly is. They have gone back to the sneaky, hiding things PN that I left because of last time, some years ago, and why I will leave again, when it suits me.
