I would like to know the definitive answer to the following question;

I am approaching the roundabout from the east on the A316
I want to proceed along Eastern avenue in a westerly direction A39

I would like to know step by step, which lane to use on my approach, which lane to use after the give way, how I should proceed across the roundabout, which lane I should use to exit the roundabout and how I should indicate to continue my journey.

For the purpose of this exercise, I will insist that indication is used throughout (where necessary) in your answer. Answers containing "I never bother indicating at all" will be consigned to the bin smile
If someone could embed this image into the post I would appreciate it thumbup........too much of a fool to do it myself biggrin

Not part of the "why don't you indicate thread" !

Have to agree but for clarity, right hand lane on approach, Inside lane on the roundabout (closest to the roundabout) exit A39.

I guess you've been cut up/beeped at when doing this.

Approach roundabout, indicate right, move to right lane. Stay close to roundabout and as you pass first exit, indicate left and move to left and take exit.

You can generally think of roundabout lanes as being arranged roughly in a spiral type of fashion, though the markings are rarely drawn exactly like that, and this one appears to be no exception. So, I suppose: right hand lane on entry, indicate right, enter roundabout on inside lane. Use unmarked area to move from inside lane to outside lane. Indicate left at some point during this bit of the manoeuvre. Then turn off.

As with any roundabout, if you drive on it regularly, you may occasionally get honked at while doing what you should, and every now and again you may find yourself doing completely the wrong thing, for reasons unclear even to yourself. I wouldn't read too much into either occurrence.

Agreed, seems obvious, RH lane on approach, don't indicate until past the first exit of the roundabout...(Then indicate left, obvs)

I would do as suggested above whilst watching out for anyone who is in the outer lane who may be operating differently as there will always be some!


Same as there is always one who miss-spells there. smile

The road markings indicate that the right-hand approach lane could be used for A361 > A361, but the white line clearly directs the left lane to A361 only (see the satellite display on Google maps).

I'd use the left-hand lane for the A361 and the right-hand lane for the A39, but, as with any roundabout, I wouldn't move across towards the A39 exit without checking to my left.

Not until I find the A316 that you quote!

Assuming you mean this location, and the yellow route I have marked, then, subject to local traffic habits and volume, my default route would be as follows.

Approaching in the centre lane seems problematic to me, and there is the two-down-to-one on the exit. I assume the three lanes on the southern part of the roundabout is to keep the route from east to north clear.
Remember, you are not signalling to a formula, but to best indicate your intentions to other road users.

Is there some confusion? The link in the OP takes me to the roundabout where Eastern Avenue joins the A361.

Ok, the definitive answer then (not that it hasn't already basically been given).

As a driving instructor, this is what I would expect the DVSA to think as correct (unless the examiners at the local test centre are extremely odd):

The direction given would be along the lines of "At the next roundabout turn right, taking the second exit" - they might clarify that it is a right turn not following the road ahead.

They would then watch to ensure that the right hand lane was taken up safely on approach, and that following a mirror check and right signal was applied in good time on approach to the roundabout.

The candidate should enter the roundabout when safe and use the right hand lane on the roundabout, maintaining a right signal. As they pass the first exit, the examiner would watch for good observation and awareness on the left hand side including use of mirrors, and expects a left signal to be applied prior to moving across to the left to exit the roundabout.

Approaching the roundabout in the left lane and proceeding to the second exit would result in a serious (or possibly dangerous) fault, regardless of observation or signalling.

Approaching the roundabout in the right hand lane but treating as road ahead, so no signal given on approach, I would expect to see marked as a driver fault for signal necessary, unless the roundabout is essentially clear of traffic and no other road users were potentially affected by the lack of signal.

If the driver approaches in the left, realises their mistake, then takes the first exit instead, that would be fine.

No you can't.

Roundabout lanes are concentric (even if not actually marked), unless explicitly marked as a spiral. The difference is really important. On a spiral roundabout you generally (there are many variants...) stay in one lane after entering and that lane guides you off (therefore you shouldn't in theory come into conflict with other drivers). On a concentric roundabout you have to cross a lane to leave. Obviously in both cases, you are a spud if you don't maintain good observations and expect the unexpected and confused other drivers deciding to try and take you out.

“Approaching the roundabout in the left lane and proceeding to the second exit would result in a serious (or possibly dangerous) fault, regardless of observation or signalling.”

So that is why it is an option for horse-riders and cyclists, no?

He did say the lane markings might not reflect what actually needs to happen. The roundabout in question has gaps in the markings that you can spiral through.

Indeed, this particular roundabout is spiralled (or partly so), just disagreeing that in general you can treat roundabouts that way. You can't...

Certainly, and LGVs etc. in some situations, just not for car drivers on a driving test for cars... (at least where not specifically allowed by lane markings etc.)
