Wanted to know what you guys think on this discussion i was having with my dad about what lane to be in on this situation.
MS live map ( The exit with the building roof/petrol station is exit 2, exit 1 is off the map)

You cant quite see the whole roundabout on the ms live map, but it gives you a general idea.
My map is how it now looks (been slightly modified to fit in a bigger entrance to asda/walmart.

Basically its in bedhampton, portsmouth.
If your coming from the road below, road 1, what are the exits that RED car can safely take in the left lane.

Exit 2 - Asda (slip road) yes because its first exit and law say you have to be on the left lane, plus its more of an carpark entrance than a road.
Exit 3 - Yes as it the first exit really,

The problem being is the next exit, ive seen people go in both lanes, the inside and the outside, and travel next to each other then both try and take the exit 4

Exit 4 - inside lane only
exit 5 - inside lane only.

There are 2 lanes on exit 1, all others are 1 lane.
What are the rules here?
I say because it is a 1 lane exit and not 2 like a dual carriageway roundabout that the inside lane must be the lane, as the outside lane must turn off at the first 2 exits, otherwise you start to cross each other.
But its diffucult to say, as the inside lane isnt allow to turn off at the first 2 exits, is it allow to at the 3?

Hope this makes sense.

Are there any markings on the road? I would normally keep left if turning left or going straight on (4) if I didn't know the roundabout, using the right lane only to turn right or double back on myself.

Only road markings are that the roundabout has two lanes on it, and has lines.
No arrows at all. Basically same as the MS Live map.

Red 1-4, blue the rest.

can anyone find me official rules in this situation as i have always used inside lane. as the outside line has to cross dangerously into your lane to get that far round the roundabout.
 
The red car can take exits 2,3 or 4. The blue car should only take exits 5, 6, or 7.

If there had been a second lane off of exit 4 then the blue car would be ok to take exit 4 as well.

Thats how I'd do it anyway.

If the exit is past 12 o clock then you got in the right lane.

Thats the problem it lies right between 12 and 1, to the degree you can quite tell.

Here's what the highway code says:

there all 2 lane dual carriageway exits, this is a dual carriage way into a single lane, at around 12 oclock. with 2 possible exits before.
 
as far as i understand it , you can only go straight on in a right hand lane if the lane has 2 exits

highway code states im sure that for straight on its left only unless otherwise signposted.

I'm sticking to my guns and saying red car only for that exit. If it were two lanes then yeah both cars.

Ah sounds pretty crap then - quite a few similar roundabouts around here, of which the markings seem to change every few years.
 
Same rules as a duel carriageway, if you find yourself in the wrong lane you can change lane assuming there is space to do so and that you signal your intention. You are allowed to lane change as long as you do it safely. Of course being in the right lane to start with is best but there isn't really any hard and fast rules when it comes to exiting on the middle exits ie I mean if you aint going directly left or all the way round.

highway code has the answer
taken from here :

Its not quite as simple as that, the arrangement of the exits are very different, that map suggests that the 3rd exit is the inside, but the 3rd exit of this round about, is dangerously close to being nearly a direct line up, but with a little bit mroe round the roundabout.
Plus it has only 1 lane on the exit not 2.

It is as simple as that, on your drawn map the red car will take the outside lane for any of the first three exits 2,3, and 4. Even if exit 4 is not actually straight up but more between where you have drawn it and where 5 is then the rule still applies.
The blue car will take the inside lane around the roundabout then exit at either 5, or 6.
There is no other way to do it.
