Input for agenda item 6 concerning definition and discussion on indirect plus and direct systems for CLIV-22. All references to indirect plus or direct sensing systems have been replaced by a CLIV warning system. Definitions for indirect plus or direct sensing would no longer be needed. A proposed CLIV warning system definition is presented for review, with a CLEPA proposal to modify the definition to include assessing if a child is left in a vehicle and triggering warning signals.
