At the roundabout on the road between Wilwerdange and Wemperhardt, a female driver was forced to brake and slow down because of the lorry in front of her.
The van behind her failed to notice her braking manoeuvre and crashed into the back of the vehicle.
After colliding with the car, the van driver turned around and drove through the roundabout against traffic. He then drove off in an unknown direction. The police are seeking the white van.
Any witnesses who saw the collision or have further information should contact the Troisvierges police station at 24487-1000.
