PARIS: France, which on Sunday reduces its speed limit on two-lane highways to 80 kilometres per hour from 90km/h, will join the tier of European countries where such limits are lowest.

Albania, the Baltic States, Croatia, the Czech Republic, Greece, Hungary, Italy, Luxembourg, Macedonia, Portugal, Slovakia, Slovenia and Spain all have a 90km/h limit on such roads, which often do not have a separating guardrail.

In other countries, the limit can be as low as 70km/h or as high as 100km/h.

Here is a panorama:

Countries in the fast lane

In Germany, the authorised speed on two-lane highways outside urban areas is 100km/h. On motorways there is no limit, but in reality the average speed comes down to around 120km/h due to roadworks.

In Austria, the limit is 100km/h on highways and 130km/h on motorways.

In Britain, the maximum speed on two-lane highways is 60 miles per hour (96.6km/h) and 70mph on motorways.

In Ireland, the speed is limited to 100km/h on all national roads, including those with two lanes, to 80km/h on secondary roads and to 120km/h on motorways.

In Poland, the limit is 140km/h on motorways and 90 or 100km/h on other roads.

The strictest nations

In Sweden, the maximum authorised speed is usually 70km/h outside towns, and 110 or 120km/h on motorways. Some regions have since 2017 introduced limits of 80km/h on two-lane highways.

In Belgium, the speed limit differs according to the country’s regions. The limit on two-lane highways was decreased to 70km/h in Flanders in January 2017 but remains 90km/h in Wallonia and in the capital Brussels.

Like France from Sunday, the maximum speed on two-lane highways is 80km/h in Bosnia, Cyprus, Denmark, Finland, Malta, the Netherlands, Norway and Switzerland.

Link between limits, fatalities

Some countries, such as Sweden, have both a very low number of road deaths — 2.6 dead per 100,000 inhabitants in 2015, according to Eurostat — and the European Union’s toughest speed limits.

But others, including Germany (4.2), Britain (2.8) and Ireland (3.5), are among the top of the class when it comes to road safety in Europe while at the same time allowing speeds of 100km/h on highways.

France stands near the European average with 5.2 deaths per 100,000 inhabitants.

The European countries with the highest number of road deaths are Romania (9.6) and Bulgaria (9.9). Their speed limits are at the European average of 90km/h on secondary roads in Bulgaria and 90 to 100km/h in Romania, with a limit of 130km/h on motorways in the two countries.

Their high accident rates are attributed in part to the poor quality of the road network and the fact that many drivers have older, run-down cars.

In Serbia, where there were 8.5 deaths per 100,000 inhabitants in 2016, the speed limit, which is not widely respected, is between 80 and 100km/h.

Despite the high number of road deaths, the limit on motorways was raised to 130km/h from 120 in April 2018, to come into line with limits in neighbouring countries.
