DCAS and UN-R-171: The dictionary for understanding Tesla's certification

Tesla's European rollout of its Full Self-Driving (FSD) Supervised software hinges on a key regulatory decision by Dutch authorities on April 10, 2026. The approval depends on compliance with the complex UN-R-171 regulation, which governs automated lane-keeping systems. This decision is critical for enabling the widespread release of the feature to Tesla owners in Europe.
