Centre line diagonal hatching, what do they mean?
Discussion
I've been noticing more and more of these recently and a drive down the A303 yesterday frustrated and stopped me from overtaking until i'd looked it up in the highway code, but i'm still none the wiser.
On the centre line of a single carrigeway road, there are two dashed lines, further apart than two solid white lines and filled in with a diagonal hatching. These are not just before a junction or leading up to a dual carrigeway or any sort of hazzard but just mile after mile of the same hatched area.
Can we overtake on these? Highway Code says -:
Rule 109 - Areas of white diagonal stripes, or chevrons painted on the road. These are to sepperate traffic lanes or to protect traffic turning right.
1. If the area is bordered by a solid white line, you should not enter it except in an emergency.
2. If the area is bordered by a broken white line, you should not enter the area unless it is necessary and you can see that it is safe to do so.
3. If the area is on a motorway and consists of a triangle bounded by continuous white lines marked by chevrons, you MUST NOT enter it except in an emergency.

They're there to separate the traffic flow and to make numpties think you can't overtake.
The key is the bounding line; if it's broken you can use the area, as per your text above.
These are placed a bit too often now, and the buggers don't sweep the chevroned area. Hence they get a build up of detritus that makes crossing them a little risky.

Unless its a solid line, just ignore it - its there to scare the numpties into slowing down and drving in the ditch (not a bad place for em IMHO)
There is so much of this stuff around, a lot of it in completely the wrong places, that I'm more and more starting to ignore road signs and markings ......
Anarchy due to overzealous safery...

It's a contrived way of disinclining motorists from overtaking.
If the lines are broken, and there is hatching in the middle - feel free to overtake so long as it's safe to do so.
There's a section like this of about 2 or 3 miles on the A4074 South from Oxford to Reading. The road is as safe as an NSL A-road could be and is on a shallow arc most of the way.
There are warning signs indicating to "stay in lane".

But if you read HC rule 109 it seems you can ignore even the solid line. It is only 'should not'.
Except on motorways.
And rule 107 seems to contradict rule 109.
When are they 'double white lines' and when is it an 'area of diagonal stripes' ??? I often see double white lines that then spread apart with very short stripes between.
I got flashed at by a numpy for overtaking him across these separation zones just a few months ago. Ferkin idiot. A large dose of road rage nearly ensued!!
IMHO I think they are probably a nightmare for cyclists because numpties feel disinclined to give them a wide berth because numpty would have to enter the cross-hatchings to do so.

A 'should not' is a 'do not'. To cross a solid white line will be endorsable. Motorway or not! The 'except in an emergency' is just that!

Little Yellow Book "KNOW YOUR ROAD SIGNS" pp 43-44 with pictures says:
As per HC
"Diagonal white lines (hatched markings) may be used to separate traffic lanes, to protect traffic turning right of along the offside or nearside edge of carriageway. When an area is bordered by a continuous line you MUST NOT enter the hatched area. Where the line is BROKEN, you SHOULD NOT enter the area unless it is SAFE to do so!"
Page 44 refers to the triangular bit per HC rule 109.
"On a motorway, part of the verge or hardshoulder between the main carriageway and a slip road where the traffic passes on either side in the same direction and where the traffic must not enter except in an emergency"
Seems pretty clear to me!
Though in the case of the unbroken line, could one enter the "forbiddden zone" if overtaking something travelling at 10mph or less?

In the "know your traffic signs" book (page 43 4th edition 1995) it says 'must not' but in the HC (1999 edition) rule 109 says 'should not'. This is all for diagonal stripes or chevrons bordered by a solid white line.
Not clear at all!!!
Und so mein Freund!
Zat ist vhy ve vere buying the "Know Your traffic Signs" Books!
Plus a few others besides the HC!
(HC is OK but unclear on some rules as you say! Hence the need to buy a supplemental to clarify!)
But it does say on the unbroken solid line "should not cross except in emergency" whereas the unbroken line is "should not cross unless necessary!"
This first would imply "must not unless emergency"
But we are not all linguists and experts in nuances of English to that degree!
Agree it is unclear and would give me a right headache if I were translating this as a professional job! Or even explaining this to another Auslaender!
Half this family are dual Nat Swiss/UK and have foreign driving licences. Englisch is not our L1 so we do look at other sources to clarify things!

Once you get beyond the general appreciation of the great unwashed all things that are beyond them mean nothing. Silly lines mean nothing, particularly when enclosed in an infinate field of total silliness mostly found near a somebody elses problem field or such other experimental phenomenon set up by local authorities engaged in the notorious 1990s Bistromathic experiments. It is believed the north Walians have invested heavily in developing mathematical models for road safety based on a unique and contravercial branch of Improbability and Bistromaths called Safetycamerapartnershipstatistics. Common academic sources have discredited this recently as "totalbollocks" Spokespersons for north Wales said recently Oh Dear Nonegreen is pissd again.

(a) to enable the vehicle to enter, from the side of the road on which it is proceeding, land or premises adjacent to the length of road on which the line is placed, or another road joining that road;
(b) in order to pass a stationary vehicle;
(c) owing to circumstances outside the control of the driver;
(d) in order to avoid an accident;
(e) in order to pass a road maintenance vehicle which is in use, is moving at a speed not exceeding 10 mph, and is displaying to the rear the sign shown in diagram 610 or 7403;
(f) in order to pass a pedal cycle moving at a speed not exceeding 10 mph;
(g) in order to pass a horse that is being ridden or led at a speed not exceeding 10 mph; or
(h) for the purposes of complying with any direction of a constable in uniform or a traffic warden.
(7) The warning conveyed by a road marking mentioned in paragraph (1) shall be that no vehicle while travelling next to a broken line placed on the left of a continuous line, as viewed in the direction of travel of the vehicle, should cross or straddle the first-mentioned line unless it is seen by the driver of the vehicle to be safe to do so.

To me the only thing that is doubtful is why whoever was responsible for writing the highway code, chose in one instance to use the word "should" when clearly the word "must" would have been more appropriate.
Yet in connection with what are essentially the same markings but related to a motorway not only did they choose to use "must", but put it in capitals, bold and red. ??

Flat in Fifth said:The "rule" in the HC appears to be that "MUST" is used where there is law and "SHOULD" where there is no law.

In modern English, "must" means to be obliged to, whilst "should" (in the 2nd or 3rd persons) expresses the future intention or will of the speaker (the HC in this case); so, "you must" is mandated, "you should" is advisory. Of course, in the Bible (eg. the Ten Commandments) and Ye Olde English, "thou shalt" is mandatory - with all sorts of dire punishments for failure to comply; in contracts, the word "shall" is generally taken to imply an obligation or restriction upon the party (but, of course, the validity of that is for the courts to decide
