The video depicts a man hanging off the back of a lorry on the motorway, as he searches for an entry point in the canvas. Another person is visible on top of the lorry. The man eventually clambers inside the lorry without further incident.
The lorry's route passed in front of the new national stadium, before taking the exit towards the A3 in the direction of Metz, Saarbrücken and Livange. It appeared to be travelling on the A6, in the direction Belgium - Luxembourg. The driver had activated the hazard warning lights.
The clip was posted on Friday.
