What is the rule for emergency vehicles in a roundabout?

Go around again.

Emergency vehicles ALWAYS have the right away, wherever they are encountered, and in my opinion no passenger vehicle should be SO much of a rush as not to give it to them.

P.S. This is one of my many soapboxes.

I think @Tropical_Willie has the right of it. No rule of the road to cover that; either someone lets you in to the right lane for your turn or you go around until you can move over.

I’m sure there are places that have idiosyncratic rules about this, but my understanding is that most places treat a roundabout like any other intersection (and so the normal rules for intersections apply). The standard rules are illustrated in this video.

Upon further reflection, I’m modifying my comment above to say that there may well be places where NOT yielding to emergency vehicles isn’t illegal. But even so, would not common sense and societal ethics dictate the wisdom, empathy, kindness and safety of doing so? Shouldn’t the “rule of the road” always reflect that?

@Pachy With all due respect, I don’t think you are understanding the question. I believe there is no question about people moving over for an emergency vehicle, the OP’s question is about people get back in the right lane for exiting after moving over.

Emergency vehicles always have the right-of-way. Go around again if you can’t make your exit.

I agree. Just go roundabout again.
The words will make you out ‘n’ out
I spend the day your way
Call it morning driving through the sound and
In and out the valley

The majority of intersections in the city I live in are roundabouts.

The main rule in most places I’ve been regarding roundabouts is the traffic that is in the circle has the right of way. The circles here have two lanes and it is legal and expected that people will exit the roundabout from the inside lane. A lot of people get tripped up by that. Another rules here is no passing or changing lanes in the circle. You are expected to enter the circle in the appropriate lane for exiting the circle. This is not always the case in all cities.

When an emergency vehicle is coming to a roundabout it’s probably better for traffic to get out of the round about and then pull right. In a very large circle that is probably unrealistic. Also, no one should enter the roundabout as the emergency vehicle approaches. That’s pretty important! If no one is coming in, the traffic circle clears pretty quickly usually.

Often, people pull right while still inside of the roundabout, or just stop in the lane they are in, and that is what I think you are talking about, the aftermath of cars all jumbled up inside the circle. Probably, there is no good solution. Everyone just has to drive slowly and be courteous until it straightens out. For large multi lane circles you might have to circle round again to get to the outside lane to exit if your roundabouts require that. As I said, where I live the inside lanes exit also, so it is a nonissue.

I would check your local laws.

I was in a local city recently that had a bunch of roundabouts near the college, to aid the flow of traffic. I really liked how, when going straight, you didn’t have to stop. You just enter (as long as nobody’s coming) and stick to the right and then keep going straight off the circle. Very nice flow.

@jca That is the idea of roundabouts, impove the traffic and not stop a moving vehicle when there is no other vehicle at the intersection.
I’ve visited a couple of towns where the town fathers (mothers too) decided to install roundabouts at several intersections and promptly put in stop signs at all the entrances to the roundabouts. SMH
