The minister had previously announced that the Markusberg Tunnel on the A13 would become the site of a speed camera that tracks average speed over a set distance rather than flashing drivers at a particular location.

The section control system entered a pilot phase last year on a stretch of road between Waldhof and Gonderange with further sites to be added in the future.

“It is incredibly important to adhere to the speed limit of 90km/h in our tunnels,” said Bausch in answer to a parliamentary question published on Monday. “To monitor this, a section control radar is better suited than the classical model.”

Tunnels offer less opportunity to evade an accident, Bausch said, often leading to more serious collisions. In July, two people died with another three suffering serious injuries in an accident in the Gousselerbierg tunnel on the A7.

The minister did not say when the section control system would be installed but preliminary works are ongoing.
