Might have something to do with traffic priority. With a lot of traffic turning left on such roundabout they don't have to wait before they canturn and go, but are given priority.

In what extend this helps? I don't know...

Yep, that's a trend in the Netherlands as well, especially on rural provincial highways where there are roundabouts every few kilometers nowadays. Highly annoying, especially for trucks. It can take a truck up to 800 meters to accelerate to 80 km/h again.

Italy is not exception.

I think there is a general traffic rule (in the World) at the intersection when there is no signals&traffic lights: RIGHT OF WAY FROM THE RIGHT SIDE
In UK and similar countries it is from the left.

priority to the right has also been abused as a traffic calming measure. It's not uncommon to have a through route having to give way to a minor road, which isn't very logical from a driver point of view. This is also where most accidents occur with priority issues.

This general rule exists in Italy too but since virtually all intersections have signs, it has little practical usage, except between two dirt roads in the countryside.
Even intersections with traffic lights have give way signs to be used when lights are out of service.

Same in Spain. There is a rule in our driving code that says that vehicles coming from the right have priority in an intersection, but all intersections have either a Stop or a give way sign.

Probably those rules are left-overs from the first part of the XX century, before the mass motorization, when road signs didn't exist anywhere like today.

They still apply at all those intersections with 5+ branches, were only 2 have full priority and the rest must rely on the "right rule".

In UK and similar countries it is from the left.
In Ireland it seems to be from the right too, despite driving on the left.

I think original source of the rule for the right side priority came from knights riding horses and is based on human's anatomy (heart on the left, usually stronger right arm) rather than on where people drive.

I read on there that it's priority on the right the UK as well, although it's an unheard of rule.

Giving way to traffic from the right is something you learn for driving theory in the UK and it applies to most roundabouts. Essentially, joining traffic gives way to traffic already on the roundabout.

I didn't study for the theory test. You do give way to the right on roundabouts, but roundabouts aren't 'normal' unsignalled junctions.

EDIT: I guess I did study it, I read the highway code over and over when I was little

Yes, I had to ask that someone before I started driving in Australia (it's the same there).

And once again, another roundabout is being built in Huesca. And with this one we have... well, we have so many that I lost the count! . But the funniest fact is that this one is located in a bridge! More then.

The worst about roundabouts is people treating a roundabout as a stop sign or going over them @ 15 km/h...

If people would just use them as intended they wouldn't slow down car traffic ( ignoring trucks) at all.


Most roundabouts in cities in NL can easily be taken at 45-50 km/h yet people slow down dramatically for them.

https://maps.google.nl/?ll=51.957463...71.23,,0,-1.58
For example, I drive that route daily, I leave an extra large gap with the car in front to hopefully not have to brake yet still end up having to slam my brake even though that roundabout can easily be done @ 40 km/h with the average car.
With cutting the inside a bit even 60 km/h is doable . Yes it's not extremely comfortable but even with 4 different types ditchfinder tyres on an ages old 1993 car in the wet 50 km/h will not make it skid if you go straight on the roundabout...


I'm all for roundabouts replacing traffic lights in low-medium traffic situations.
I'm very against roundabouts replacing regular right of way intersections outside of cities.

I like roundabouts personally, they keep traffic moving better than some crappy traffic lights which are bound to slow you down!

I wish The Netherlands used FAR more bypasses though for regular intersections with traffic lights and roundabouts! There is often more than enough space, especially on N roads!
