Traffic Trap

And that 40 sign doesn't help...

Exactly, and why have they put it on the right hand side?

I also once took the right hand side, but realised my mistake at the last moment before oncoming traffic. Quickly reversed into the left hand side. Spotted this on StreeView, so I'm not the only one...

So that you can see it if there is a HGV in front of you. And, of course, there is a post there anyway for the oncoming traffic to see their limit.

Because it's part of a "gate" and, as per regs, there's one either side.

I don't quite see how the confusion can arise. To get where the RH car is you have to cross the central white line while in a two way road - see Driving 101. Is there something further back (or the general road layout of the area) that makes people think it's a dual carriageway then?

Hard to tell when there is an enormous sign just before the view shown, that shows that the road goes to the left and joins a big roundabout.

Northern way, Reading. https://www.google.co.uk/maps/@51.4254462,-0.9826627,3a,75y,33.45h,79.72t/data=!3m6!1e1!3m4!1sSn5oJdRLRBxydx40e4B3Ng!2e0!7i13312!8i6656

And then there's a 'Keep Left' arrow at the 'fork'.

Would it not comply if the 40 sign was moved to the same location as the keep left bollard? That would make it much more obvious IMHO.

The other way to make it clearer would be to use a cross-hatching marking on the lane divider.

It looks confusing to me; if you were unfamiliar with the area, and struggling with navigation, it doesn't look obvious what you should do at all.

Your view would make it a much more obvious candidate for some additional paint on the centre line, either hatching or double white lines.

Yep, could happily go on an island and I agree it would probably help the initial situation, it just seems there isn't much of an island to put it on which is probably how it ended up where it is.

FWIW, I loathe these speed limit changes on a junction. Many other, more important things to be concentrating on with the worst case side effect of getting done by a camera on the road you're joining.

I'm curious; which bit? It's a S/C road joining a large roundabout, not disimilar to any number of m'way junctions. Being on the "corner" of the roundabout does make the flow onto it a sharp left turn while the oncomming flow is a straight line, which could, at a push, make it seem like a left off-slip, but there's still got to be the working assumption of being on a D/C to cross the white lines.

Being on StreetView with the wide angle and somewhat birds eye view doesn't help view it as you'd see it from a car though.

I said that the markings are officially correct, but with a high proaility that a mistake will be made. I once nearly took the right branch, then I spotted the car on StreetView doing exactly the same. Call me the weakest link if you like. We all have weak moments...
