Intelligent Speed Adaptation (ISA) is an on-board system that helps the driver comply with speed limits. It uses GPS to connect the vehicle to a digital road map and either advise the driver of the limit (advisory ISA) or intervene with the controls to ensure adherence to the limit (mandatory ISA). Use this page to access the latest initiatives in ISA worldwide.
