Roundabout Rules by Country 2026 — The Right-of-Way Trap in 14 Countries

In most of Europe traffic already on the roundabout has priority — but 14 countries still have junctions where it does not. Which ones, and how to read the signs before you enter.

Quick Answer

In most countries you give way to traffic already on the roundabout. The key exceptions: France requires giving way to entering traffic at some older roundabouts marked 'Vous n'avez pas la priorité'. Australia, UK, Germany and the US follow the yield-to-circulating rule. Signalling on exit is required in Australia and the UK.

The roundabout seems simple: it is a circular junction where traffic flows in one direction. Yet roundabout rules generate more confusion among international drivers than almost any other aspect of driving law. Who has priority? Which lane should you be in? Can you change lanes on the roundabout itself? And why does France seem to operate differently from everywhere else? This guide answers all these questions, country by country.

The Standard Rule — Traffic on the Roundabout Has Priority

The modern rule applied in the vast majority of countries is: traffic already circulating on the roundabout has priority over traffic entering it. This is the rule in the UK, Germany, Netherlands, Belgium, Spain, Italy, Portugal, Scandinavia, Australia, New Zealand, South Africa, and most of the world.
In practical terms: when approaching a roundabout, you must give way to any vehicle already on the roundabout. You enter only when there is a safe gap. The “give way” markings at the roundabout entry confirm this — in the UK, they are dashed white lines; in Germany, they are “Vorfahrt achten” (yield) signs; in Australia, “Give Way” signs.

United Kingdom — Roundabout Capital of the World

Britain invented the modern roundabout. The UK has more roundabouts per capita than any other country — approximately 25,000 — and British drivers are generally very comfortable with them. Traffic on the roundabout has priority. Lane discipline on multi-lane roundabouts follows the Highway Code guidance:
  • Turning left (1st exit): approach in the left lane, signal left, stay in the left lane on the roundabout.
  • Going straight on (2nd exit): approach in the left lane (or right if signposted), signal left after passing the 1st exit.
  • Turning right (beyond 12 o’clock or last exit): approach in the right lane, signal right, remain in the right lane until ready to exit, then signal left.

The most common error on UK roundabouts is lane-changing mid-roundabout without signalling, which causes a significant proportion of minor collisions.

France — The Historical Exception

France is responsible for more international roundabout confusion than any other country. The traditional French driving rule of “priorité à droite” (priority to the right) gave priority to vehicles entering from the right — which at a roundabout meant vehicles entering the roundabout had priority over vehicles already on it. This was the opposite of the standard rule.
In 1984, France updated its traffic law to align roundabouts with the international standard: circulating traffic has priority. “Vous n’avez pas la priorité” or a give-way sign at the entry makes this clear. Modern roundabouts in France all follow this rule.
However, older roundabouts — particularly in smaller towns and villages — may still have old signage or the traditional rule, especially if the roundabout was built before 1984. The key is the signage: if there is a “cédez le passage” (give way) sign or dashed lines at the entry, you yield to circulating traffic. If there is no such sign, old priority rules may apply. Treat any unsigned roundabout in France with caution.

Germany — Clear and Consistent

Germany’s roundabouts are uniformly governed by the same rule: circulating traffic has priority. This is indicated by a “Vorfahrt achten” (yield) sign or a “Stoppzeichen” (stop sign) at the entry, plus yield line markings on the road. German roundabouts typically have a maximum speed of 30–50 km/h and a legal prohibition on overtaking within the roundabout.
Since 2000, many German roundabouts have been converted from traditional crossroads to mini-roundabouts, especially in urban areas. These operate on the same priority rules but are physically much smaller.

United States — Still Learning

Roundabouts are a relatively new feature of American road design, though their numbers have grown dramatically since the 2000s. The Federal Highway Administration actively promotes roundabouts for their safety benefits: they reduce severe injury crashes by approximately 75% compared to conventional intersections with signals.
US roundabouts follow the standard rule: yield to circulating traffic. “Yield” signs at the entry are standard. Despite this, driver confusion at roundabouts remains higher in the US than in countries with longer roundabout traditions. Pedestrian crosswalks at the entries of US roundabouts are a common interaction point that European drivers may find unusual.

Australia and New Zealand

Both countries follow the standard rule firmly: circulating traffic has priority, indicated by “Give Way” signs. Australia’s roundabout culture is well-established, particularly in Queensland and New South Wales, where many intersections have been converted from traffic lights to roundabouts.

New Zealand’s Highway Code is explicit: give way to all vehicles already on the roundabout. On multi-lane roundabouts, lane discipline follows similar conventions to the UK.

The Netherlands — Cyclist Priority

The Netherlands adds a layer of complexity that surprises many visitors: at many Dutch roundabouts, cyclists have priority over motor vehicles. The distinctive red cycle lanes crossing the entry and exit points of the roundabout are where you must give way — not just to other cars, but to any cyclist using the marked cycle path.
This applies at roundabouts with the specific cycle priority marking. Not all Dutch roundabouts have this rule — check the road markings. The cycling priority roundabout is becoming more common in other European countries, notably Germany and Denmark.

Mini-Roundabouts

Mini-roundabouts (the very small ones with a raised or painted central circle) operate on the same priority rules as full roundabouts, but drivers may straddle or drive over the central marking if necessary for larger vehicles. In the UK, mini-roundabouts are extremely common and drivers may encounter several in quick succession (the infamous “magic roundabout” in Swindon consists of five mini-roundabouts surrounding a central roundabout). The standard priority rule applies throughout.

General Tips for International Drivers

Observe local traffic before entering an unfamiliar roundabout — watch a complete circuit to identify lane usage and priority. Approach slowly if you are unsure. It is always safer to give way when in doubt, even if you technically have priority — the cost of yielding unnecessarily is much lower than a collision.

Finally, on multi-lane roundabouts in any country, be particularly aware of large vehicles (trucks, buses, coaches) that may need more space than their lane technically occupies. Give them room.

Get a roundabout wrong abroad — taking priority you don’t have, or stopping dead where the flow expects you to keep moving — and it can mean a fine or a collision claim against your hire car. Who actually pays a driving fine abroad covers how those tickets and the rental admin fees find their way to you.

Frequently Asked Questions

In most countries including the UK, Germany, Australia, and the US, you give way to traffic already on the roundabout (coming from your right in right-hand traffic countries). France historically required giving way to entering traffic in some cases, but now follows the standard rule at most roundabouts.

France historically applied the 'priorité à droite' (priority to the right) rule at some older roundabouts, meaning entering traffic had priority. However, since a 1984 rule change, modern roundabouts in France follow the standard rule — traffic on the roundabout has priority. Older roundabouts may still have different signage.

Lane changing on roundabouts is permitted but must be done with caution. Signal before changing lanes, check mirrors and blind spots, and be aware that multi-lane roundabouts are higher-risk areas for side collisions. In the UK, following lane discipline (left lane for exits up to and including 12 o'clock, right lane for exits past 12 o'clock) is advised by the Highway Code.
