Does anybody know how much liability does Hertz and Avis provide in the state of Florida or how to get that info?
There is an image of a chart in a post above with all the state minimums, for Florida it is 15/30/15 and that's what Hertz provides, Avis's website seems to indicate that they also provide up to the state minimum.
Take note, however, the liability Hertz provides is only secondary to any other liability coverage you may have, the same is true in every state except California where there is no coverage and Arizona, Maryland, Massachusetts, Michigan, Minnesota, New York, South Carolina, Virginia, and West Virginia where they provide primary liability.
Similarly for Avis, in California and Texas they do not provide any liability, in Missouri and Utah they only provide liability if the renter has no liability him/herself, in New York they provide primary and the other states are not specified but it seems to imply that they all have primary liability provided up to the state minimums.
