Not listed on this AAA page with Hertz benefits, so it may have changed:

It's a bit of an odd benefit anyway, given that most AAA members would have a car and thus have liability insurance already. I understand the appeal of trying to keep a claim off your own insurance, makes perfect sense. But I can also see why they may have ended this benefit as it wouldn't be especially important to most members.
