Spotted a new one inside Portsmouth International Port. It took me a moment to realise because the signal head on the left made it look legitimate. But the one in the middle is quite something.

Switch to history view to see it was accompanied by an overhead signal too.

Near to the infamous Beverley Traffic Light Forest! I go past these left filter lights a lot and can't think of a scenario where they would ever need to change to red or amber. There's no pedestrian crossing here either.

Coming off the A30 Eastbound at Tolvaddon a new set of lights were installed after the junction redesign, coming off the right turn lane is operated by a changing set that works against the opposing traffic but the ahead only lane is separated by pavement and has separate lights that always show a green ahead arrow, my driving instructor mentioned once that he thought that the nearby fire station had some form of control over them but i highly doubt this as it is on the next junction and there would still be the factor of the traffic heading for the Westbound A30 & Tolvaddon.

Annoyingly if you move to the Left hand side of the road on street view it shows the old uncontrolled junction.

Shame they removed a lane too, really ...

I can see the benefit of separating with an island to bypass the signal control for straight-on traffic, I’m not convinced they couldn’t have done it without losing that lane

The extra lane could have been kept but traffic flows pretty well heading off Eastbound, but there is very little traffic turning right in to the village or on the way to the North Coast. My main irritation with this junction design is that traffic heading for the Fire Station or Roscroggan are expected to go through the ahead only lane and then cut across a lane (and possibly hatched markings) of traffic to turn right at the next junction! The Right lane in my opinion should be Ahead or Right, with clear signage indicating that traffic for Fire Station & Roscroggan should use lane 2.

The local fire crews have solved this issue by of course using the right turn lane to proceed ahead when green but anyone not local looking for Roscroggan would use the right hand lane (sign on slip road shows Roscroggan as second right) and either have to cut across or loop all the way back up to the Old A3047 or the services to loop around as all the lights are No U-Turn.

This section of road's junctions are notoriously badly designed, in fact I think I went to school with the child of the person (or one of the people) who designed it (I also think they know this pretty well by now).

This little arrangement on the A35 in Boscombe near Bournemouth removes any permanent green for straight ahead and replaces it with a tatty sign ("Signals for Right Turn Only").....

This is what I thought of when I saw the title of this thread. The left-turn filter has always been lit whenever I've been past on holidays to Brixham and I see no reason for it to ever not be. I've even looked to see if there are signals on the little side road immediately after the junction but it is one-way up the hill.

What about the M25?

While there is no explicit signage for which lane to use, the right-hand lane is NOT right-turn only.

If it was there would be an arrow on the road, a sign on the lights and probably a buildout forcing traffic to turn.

Presumably the designer assumed that people wanting the second right would use the right-hand lane anyway and wouldn't need explicit instructions.

Is the green aspect for that lane an arrow?

Right you are, that is not a legally enforceable right turn, that's just my poor choice of words, and yeah the locals are happy to go straight through but I just meant that the direction signs themselves don't list the destinations for the second right turn in the lane 2 box of the new sign (The green backed primary sign on the exit slip has been replaced by a non primary one which shows the two separate lanes but not which to use for the second exit, lane 1 is marked as the straight on lane so any sat nav followers would likely commit to this lane.

Unless the signals display an arrow pointing to the right, in which case an ahead movement would be an illegal contravention of the arrow.

That has to be one of the shallowest angles on a pair of diagonal arrows sited together!

But it is okay to go into oncoming traffic if you want.

These in Edinburgh are quite shallow.
