What is the speed limit on a roundabout please?
Discussion
Only I'm being asked to give the speed limit in force at the site of a small accident.
As a visual guide, imagine a roundabout with a dual carriage way branching off at 12 o'clock and 6 o'clock and a country road crossing it from west to east.
Dual carriage way has a 60 limit both sides of the roundabout and similarly the country road has a 30 limit both sides with the accident actually happening on the roundabout itself between a car crossing west to east and a car crossing south to north.
Many thanks for any help you can give.

Multiply the different speed limits for all the exits, then add on their relative positions (24h clock, not 12h).
Seriously - it is likely to be the last speed sign you past before entering it - so if you are on a dual carriageway with a posted 60mph limit and there's nothing before the roundabout to change that speed limit, it is 60mph.
However, you do still have to take care on a roundabout, so can't just claim "limit is 60mph therefore I'm safe".

Depends on the limits either side, Street view would help.As a visual guide, imagine a roundabout with a dual carriage way branching off at 12 o'clock and 6 o'clock and a country road crossing it from west to east.

Google Earth picture may help. I should have thought there would be limit/change of limit sign fairly adjacent to either of the two roads crossing it.
Yeh, I would expect so, too. All the entrances/exits will be the same limit, and that's the limit that'll apply.This does NOT mean it's wise to try to achieve that limit around the r'a'b...

Ah-ha I see, are you saying that you think there would have been a meeting of speed limits on the approach to the roundabout? The DC would have stepped down to 30 as it approached the roundabout so as to be in-line with the country road it was about to meet at the roundabout?OK, I can check using street view.

Go to Google street view and approach and 'Drive' round the roundabout from each direction. Either the DC will have 30 signs before the roundabout or the side roads will have NSL (or 60) signs before the roundabout - that'll be the answer you're looking for.As a visual guide, imagine a roundabout with a dual carriage way branching off at 12 o'clock and 6 o'clock and a country road crossing it from west to east.

I'm not quite sure what the speed limit has got to do with it anyway, the car that didn't give way at the give way line is in the wrong!
The speed limit of the road you were travelling on applies.
Most roundabouts that I can think of have speed limits on the exits, to indicate the speed limit of the road your joining.
The roundabout in question might be different so I wouldn't say for sure.
ETA: I actually can now think of a roundabout that slows you to 30, 10 yards before it on one approach but all other exits are 30 roads.

Thank you everybody for your input.
When I was learning to drive 42 years ago my dad (a police officer at the time, not trafpol) told me that roundabouts were limited to 40mph.
Can't say I think about it very often but I guess I've been believing that without question or checking it in any way ever since
He's 83 now, I think I'll just let it lie.

But did he mean speed limits or driving ability limits? Can't say I think about it very often but I guess I've been believing that without question or checking it in any way ever since

If it's in relation to insurance liability speeding doesn't always mean they were the most negligent.
If someone pulled out into the path of a speeding vehicle they either looked at the vehicle, seen it was speeding and decided to pull out anyway, or else looked at the vehicle but not long enough to see what speed it was doing before pulling out.
