What is a passive ignition cut off system?

A passive ignition cut-off system is a safety feature in vehicles designed to automatically disable the engine's ignition in the event of a collision or other emergency situations. This system typically uses sensors to detect sudden deceleration or impact, triggering the cut-off to prevent potential fires or further damage. Unlike active systems, which require driver intervention, passive systems operate automatically without any action needed from the driver. This enhances safety by ensuring the vehicle cannot be inadvertently restarted after an accident.
