So a little over a year ago, I posted this thread discussing insurance rates increasing as the insurance industry enters a hard market:

While the commercial auto insurance market has taken rate increases, they were not as high as I was suspecting (in some rare cases we have seen 20-25% increases, but it is between 6%-8% and in some cases remaining flat at renewal. The majority of rate increases on good/loss free operations are in the Physical Damage premium moreso than in the Liability portion.), however Hurricane Sandy could have an affect on this market due to the number of vehicles lost in the flood--250,000 vehicles are estimated to have been destroyed.

I do not assume that all of them were insured against physical damage loss, however I would suspect that a large portion of them were.
