EuroTest has now tested Europe's motorway road work zones for the third time, making this test a permanent part of the international test programme involving 16 motoring clubs. The focus this time round was on 50 motorway road work zones in eleven European countries: Eight in Germany, seven in Austria, five in both Italy and Switzerland, four in France, the Netherlands and Spain, three in Croatia as well as two in both Denmark and Slovenia. And then there was the special situation in the UK where three road work zones were checked during the day and then again at night. The reason for this is that many road work zones on mainland Britain are changed completely at night, so that work can be intensified during low-traffic times. Due to this, it is not possible to compare the results of day and night measurements – extra testing at night was necessary. All of the sites tested were long-term road work zones on main European travel routes. The shortest road work zone was one kilometre long, the longest around 20 kilometres.
