French State expands automated control system

Starting in 2026, the French government is preparing a new automated control system that goes beyond traditional traffic violations. This system will include measures such as eco-tolls, noise detection, and carpool lane enforcement, which could lead to more fines for drivers and transporters.

System targets more than just speed

The automated system, which has previously focused on speed and red light violations, will soon expand to include noise, carpooling, and green taxation. These changes, though subtle on paper, could significantly affect how drivers and transporters interact with the road network.

Centralized processing of fines

Currently, most automated radar data is sent to a centralized processing center in Rennes. There, officials review the information and issue fines to vehicle owners. With around 4,600 radars in use, the system already generates nearly 16 million fines annually.

Decentralized control for local decisions

A new aspect of the system is the decentralization of decision-making. Local authorities will now have the power to validate certain violations directly, rather than all decisions going through the Rennes center. This change is part of a broader initiative called the Decentralized Automated Control (CAD).

Eco-tolls in Alsace as first application

The first concrete use of CAD will be the implementation of eco-tolls on Alsace roads starting January 1, 2027. Heavy goods vehicles that fail to pay the toll will be fined remotely. This system is expected to expand to the entire Grand Est region by the end of 2027.

Noise radars and carpool lane enforcement

Noise radars, which measure noise levels and issue fines if thresholds are exceeded, are set to be approved by the end of 2026. Carpool lane enforcement will also be automated, allowing remote fines for vehicles not meeting occupancy requirements on those lanes.

New control for vehicle weight limits

The system will also include automated enforcement of weight limits for heavy goods vehicles. Two public tenders have already been awarded, marking the first step toward automatic sanctions for overloaded trucks.

No mention of low-emission zone radars

The government’s tender document does not mention specific radars for low-emission zones. However, it estimates that the new system will process a volume of fines similar to the current automated radar network, around 16 million annually.
