📋 Tender Overview
The two radars installed at the end of October 2025 on both sides of the A3 motorway to monitor the third lane intended for carpooling will begin a test phase from Monday December 1, 2025. As a reminder, as part of the project to widen the A3 motorway, a first step was taken in March 2025 with the opening of the first section to 2x3 lanes and the introduction of the first carpooling lane in Luxembourg, connecting the area from Berchem to the Gasperich cross. On a first portion, the left lane is exclusively reserved for carpooling and buses. Also, only vehicles with at least two people on board can use it. From Monday, the radars, each oriented towards one direction of traffic, will monitor vehicles traveling in the carpool lane. They are equipped with cameras to recognize silhouettes, in compliance with current legislation regarding data protection (GDPR), and to determine the number of people in the vehicle. During this test phase, no taxed warnings will be issued by the automated control and sanction system. The start of the repressive phase will be communicated by the competent authorities in due time.
