Dutch Regulator Cuts How Far Over the Speed Limit Tesla's Driver Assistance May Go
The RDW, the Netherlands Vehicle Authority, said on Nov. 3, 2026, that it has approved changes to Tesla's FSD Supervised driver assistance system, renaming it Tesla Assisted Driving and cutting the speed margin a driver can set from +50% to a maximum of +10%.
That margin is the setting that decides how far above the posted speed limit the system may drive. The RDW describes it as a percentage by which the system may deviate from the applicable limit when safety or traffic flow calls for it. Under the old setting, a driver could let the car run half again as fast as the limit; the ceiling is now a tenth above it.
The regulator also said that the margin now defaults to a 0% deviation whenever the car is started, and that other speed-related functions are off by default. The new name is to appear on the in-car display, in the manual and in all other driver information. Both changes apply to Tesla models fitted with the system and with hardware version 4.0 or later, and the RDW said Tesla will deliver the update over the air.
The RDW granted the original type approval, a model's regulatory permit to be sold. It said the manufacturer asked it to assess a number of minor changes, which it then folded into the approval already granted. That approval stays valid under the same conditions and does not have to be amended or extended. The RDW also said the new name does not alter how the system works: it remains a driver assistance system that supports the driver, and the driver stays responsible for driving.
In its own account of the assessment, the RDW said it checked how the changes were implemented and how the system behaves as a result, and identified no adverse or unintended effects on the system's operation or on the car's driving behavior.
The RDW said it has informed the nine member states that have accepted the type approval: Belgium, Croatia, Czechia, Denmark, Estonia, Latvia, Lithuania, Slovakia and Slovenia.
