But Riggers .. all too often .. sigh.. these paint jobs of the broken hatchings. .. they just paint jobs.
They narrow the carriageway. Create congestion.
I have photo of what was an NSL dual carriageway (A57 on approach to Warburton Toll Bridge as taken by Mad Doc's sister Ju-Ju. (She one steady driver by the way. She never ever goes above any speed limit. She IAM trained like rest of us.. but she just drives without exceeding any limit regardless. How she does it? She sets her cruiser und her origin to blip if she ever go over. She say these help her get the discipline as each time her origin bleeped .. she reigned in. Now she used to "feel of the speed" more acutely. Which ist yet another example as to how to use the toys available to us really. But she not enjoy fast or fast fairground rides either.

)
But anyway .. back to her photo of A57 which she condemn as "engineered congestion to justify some charging" I have not got this uploaded to our hoster as yet. I will ask her to do so. She better photographer und scanner than Jazz who ist "come day /go day" on this skill.

But I have seen her photo. L2 ist hatched with solid white forcing all into one lane. No reason for this at all. It lead to congestion in the area as road space removed. Before this Ju-Ju said there was courteosu zip-merging which meant traffic actually did move, albeit at no more than 20 mph in "peak morning" towards the lights at the junction with the quaint toll bridge.l
Another example... we have a few here .. in Penrith/Kendal/Carlisle - but I think more a 'burb problem than a rural market town problem really.

But in the Manchester burbs.. the in-laws tell me that A575 Walkden to border with Farnworth has these hatchings with pedestrian traffic islands. They say more minor scuffles occur there.
They then re-engineered the next section.. revertin back to wide carriageway. They also re-engineered the wide traffic lights where two girls were killed in the drunken DJ incident which Mad Doc reported on at the time it happen. But.. less incidents reported since they returned to sensible road markings und carriage widths here

Or at least none reported in press or heard about by the local riff raff belonging to Ted's family
A575? It really now a question of good COAST skills per the in-laws because of now bizarre road engineering experiment. It not actually work.
They are broken hatchings.. but pedestrian islands prevent overtakes or cause incident when drivers do pass a stopped bus there.
If broken lines, clear und zero reason not to overtake something.. then go for it as/when safe und legal to do so.
