Greetings,

Portsmouth is now happily putting speed signs all over the tarmac of the M275 reducing its entire length to 60mph with 50mph on the sliproads. Am I right in saying that as its entire length is now permanantly being set at a limit of less than 70 it should no longer be classified as a motorway when the signs go up?

Nope. The national speed limit on motorways is 70mph. The fact that the M275 is having limits set lower than that doesn't stop it from being a motorway, with all the extra regulations that that implies.

Seems logical doesn't it but I can think of anther couple of places round my way where there is a lower than national limit on a motorway.

Theres a 50 limit on the M4 ( complete with gatsos ) near Port Talbot. I believe because its on an overhead section near houses its to reduce noise levels - nothing to do with safety

So the slip road to allow you to accelerate up to speed with the rest of the traffic has a lower limit than the road it joins...

Thats clever!

actually the speed limit there is to do with safety, all the slip roads on that bit are very short, so the limit is lower, so you don't emerge into fast moving traffic, whilst still going slowly.

In Norfolk you could build a sliproad a mile long and the slowsters will still amble up at 45mph then brake at the end....

Setting a lower limit on the sliproad (assuming it's the onslip) is clearly the work of somebody who doesn't understand how these things are supposed to work.

But why can these imbeciles get into positions where life and death decisions like these are routinely made like they're choosing the colour of the new conference room. And stranger still, how come the committees that surely review thise dumbarsed proposals don't see the stupidity and bounce them back?

Parts of the M4 and A102(M) have limits of less than 70MPH, but both are defined as motorways.

What makes you think motorway must = 70MPH ?

And the sneakiest speed camera in the country is on a 50mph section of the M11 IIRC

Do you know what their reasons are for that? Who makes the decision?

For the entire length of the motorway in question?

These are supposed to be long term temporary limits while Tipner gets bulldozed and rebuilt. They're not in force yet, even though the signs have been painted onto the tarmac-wait for the roundels to appear (quickly followed by the cameras).
However, some might say that the M275 isn't much more than one long sliproad anyway....

Southbound, just as the M11 reduces down to two lanes, as it is about to join the A406 North Circular.

I think it had the distinction of being the most profitable camera in the country.

I know it well (thankfully have never been caught by it.)

Difficult, as alot of people go through it at way over the limit, so it is reasonable to assume it is not active. However, this is a main route into East London, and the proportion of vehicles with duff registration details in this area is massive.

Hence, the Local Boyz carry on with impunity while everyone else is stuffed.

Off at a slight tangent here, but...

Q: When is a motorway not a motorway?
A: When it is a 3-lane dual carriageway. Only difference is green signs rather than blue signs, but otherwise identical apart from one crucial thing - learner drivers are allowed to drive on this. This is how I managed to acquire motroway training & experience before I had passed my test.

Not the answer you were looking for, but a valid answer to the question.

Err, not quite, because a 3 lane DC was never a motorway.....

There's a saying that goes something like "if it looks like a duck, swims like a duck, and quacks like a duck, then it is a duck".
In the same way, I was saying that a 3-lane carriageway with armco on either side, a hard shoulder, slip roads on and off and indistinguishable from a motorway in all respects other than green signs rather than blue, is a motorway in all but name.

Therefore,
Q: When is a motorway not a motorway?
A: When it is a 3-lane dual carriageway as mentioned above (and/or it quacks).
