SAE automation levels: a reminder
SAE levels: level 0 (no automation), level 1 (assistance, e.g. cruise control), level 2 (partial, e.g. Tesla Autopilot, VW Travel Assist), level 3 (conditional, the vehicle drives alone but the driver must be able to take over), level 4 (high, no driver in some conditions), level 5 (total).
Level 3 in France since 2023
The 2022 Mobility Orientation Act and decree n° 2023-234 officially authorised level 3 in France on 1 September 2023. The Mercedes S-Class and EQS are the first homologated vehicles with Drive Pilot. In 2026, BMW 7 Series and Mercedes E-Class join them.
When can level 3 be activated?
Very strict conditions
Only on motorways (not urban expressways), speed limited to 60 km/h (130 km/h allowed by Mercedes in some US and German cases, but 60 km/h in France in 2026), mild weather (no heavy rain, no thick fog), dense traffic (traffic jam), visible road markings.
Concrete use examples
A Paris-Lyon trip in a jam at 50 km/h: Drive Pilot can drive for 1–2 hours while you read, watch a film or work. Mercedes and BMW even legally allow displaying text on the central screen.
Liability: who is responsible in case of accident?
While level 3 is active
The manufacturer holds civil liability for any damage caused by a system failure. A new dedicated "manufacturer liability" insurance category is required (included in the Mercedes/BMW purchase price).
At handover
The vehicle warns the driver 10–15 seconds before handover (motorway exit, sudden rain, emergency slowdown). During this phase, liability switches to the driver.
Technical failure
A logbook records all parameters in real time. In case of accident, this log is transmitted to the authorities (CERT). The new legal procedure may take 12–18 months to determine liability.
Licence: no change
The classic B licence is enough. You need no specific training — in theory. In practice, Mercedes, BMW and other makers offer free 2-hour sessions to tame the system. Strongly recommended.
Current 2026 limits
The system deactivates automatically if: invalid markings, tunnel, toll, strong weather, camera/lidar/radar failure. In that case, takeover mandatory within 10 seconds — otherwise, auto slowdown and stop.
What about levels 4 and 5?
Level 4 (driverless in a defined perimeter) is not yet allowed for private users in France in 2026. Only autonomous taxi fleets under trial are homologated (Paris, Saint-Cloud, Vélizy, Toulouse). Level 5 (fully autonomous) remains a 2030–2035 horizon goal.
