Three lane roads ....

hope not because all the three laners around here were converted to two lanes and you have to cross the median to overtake anyway so where is the problem having a two way dedicated overtaking lane.......?

so having no hard shoulder on smart motorways is not as bad then ? ....

only now replaced by no hard shoulders on motorways ...

By "work" do you mean Darwinian selection program?

It happens that snipped-for-privacy@moo.uklinux.net formulated :

I often used to see three lanes where one side has a dotted line plus solid line separating them from the middle lane and the other just a dotted white line. Basically that means the first side can use the centre lane to overtake, but the other lane has priority use of the lane.

I don't know if it still true, but some of Leeds ring road was marked like that, as was part of the wide A64 near Scarborough.

The latter was wide enough to easily support four lanes, but had a dotted single line down the centre - the markings, meant that many of the slower drivers would drive close to the centre, making it risky and necessary to over take on the on coming side of the road.

Nightjar used his keyboard to write :

Quite common around here too.

The hell it does!

It means you can't cross from the side with the solid line.

Two solid line means you can't cross it from either side.

Or at ;least it does in the UK.

They do exist in places, e.g. A65 Settle by-pass

- with a strategically placed lay-by for the speed camera van just beyond the trees in the distance on the right.

Think again, or maybe look it up!

Not sure about that ... surely it means traffic from the other direction can't cross the solid line to into what would be the third lane for them?

A variation I've seen in the US is to have a normally 2 lane road, with a periodic 3rd overtaking lane also in a single, alternating direction.

Not being legal to cross, is marked by double white lines. Then the centre lane is for exclusive use of the other side of the road, but even then, there is an exception - you are allowed to cross a double white line, to pass a very slow moving vehicle 10 or 15mph (I think) and always providing it is safe to overtake, nothing coming the other way in the middle lane.

10mph and the white line rules are explained here..

no, a single line is not legal to cross if it's on your side, a double line is simply not legal to cross from either side (except when slowly overtaking slow traffic, or turning across the road)

yep, but you can't overtake a 10mph tractor at 60mph

Andy Burns was thinking very hard :

[1] A dotted line on your side, with a solid white line at the far side, can be crossed, if it is safe to do so.

If it is a three lane road, with just a dotted line separating the opposing traffic, from the centre lane, then they have priority use of the centre lane. If your side of the road is separated as described at [1], then you can overtake using the middle lane, providing it is safe to do so and there are no opposing vehicles likely to need used it.

It would be stupid to do so, but there is nothing in the regulations to prevent it, so I don't understand your "can't". You overtake a slow moving vehicle with extra care, but on the other hand you don't hang about.

Like this?

And on a bend!

Is the only one I know of.

You call that a bend?

A good near straight road, with long sight lines, I don't see any issue. Where sight lines decrease, cresting a slope, the RH side is prevented from using the middle lane by a double white line. A very safe road.

I can't see anything in the HC, RTA or TSRGD to confirm that.
