Intelligent speed adaptation (ISA) is designed to work much like cruise control to prevent the vehicle from traveling over the speed limit, or to warn the driver about the speed limit.

Where the ISA prevents the driver from travelling over a set speed limit, there may be a temporary override; this can be logged to find out if its use contributed to an accident.

ISA that warns the driver is required for new EU light duty vehicles starting in 2022. It can use both Advanced driver-assistance systems (ADAS) and geofencing.
