DS II Question

Hey all:

I'm re-reading my DS II rules (I have a lead on some players in my area)
and
I had a question about damage.	What happens if a vehicle takes a second
"Damaged" result?  Is it KO-ed, are the stats halved again, or nothing? 
I
couldn't find anything in the rules to confirm this.

Later,
