The average speed radar measures the speed of drivers over a particular distance, unlike a normal speeding camera, which snaps speeding drivers in one location.

The Markusberg tunnel is located near Schengen in direction of Germany. One driver last month raced through the tunnel at 194km/h, the transport ministry confirmed to Delano, more than twice the legal limit.

There were eight so-called “délits de grande vitesse” in December at which the speed limit is exceeded by at least 50% or a minimum of 20km/h.

A ministry spokesperson said the numbers are “alarming”. Research shows that the risk of being killed or seriously injured in an accident is higher in tunnels than on the motorway.

The Markusberg average speed radar marks the second such device in Luxembourg with the first located on the N11 between Waldhof in Gonderange. In the first three months of being operational, the radar caught nearly 1,500 speeding drivers, a fraction of the offences caught on the A13 in just one month.

Luxembourg introduced fixed speed cameras in 2016. There are currently 24 such devices scattered across the country. In July this year, the grand duchy added to its arsenal of speed cameras by adding a red light camera at Place de l’Etoile, which captures drivers running the red light at the intersection that crosses paths with the tram. During its first month, the camera , including regular speeding tickets.

Last year, 26 people , up from 22 in 2019, even though the overall number of accidents diminished by 20%--although the March to May pandemic lockdown could be behind this decrease.

Speeding and driving under the influence of drugs and alcohol were among the leading causes of fatal and serious accidents.
