Based on the discussion, the transport ministry said, "Since no manufacturer knows which particular product will be registered as a cab or transport vehicle, the solution has to be at the end when the dealer dispatches the vehicle. The manufacturers have said there are ways out and passengers to disable the child locks before starting the journey.”
Recently, the Delhi government had issued a notice to commercial vehicle owners and drivers to use a sticker cautioning passengers to disable the child locks before starting the journey. This norm comes to effect late this month.
In a child lock system, the doors of vehicle are locked in a way that they open only from outside. As the name suggests, the feature was meant to protect kid passengers from accidental gate crashes by disabling the locks inside the cabin.
