Law

Well, jeepers, if you're a lawyer, you should know that the laws vary throughout the United States. There are states that don't have PIP.

Plus this is an international forum. I doubt that PIP is available in, say, Bhutan.

And before anyone rails about me answering a bot or a spammer, the question can certainly be a legit one. Plus I'm cranky this morning.

PIP is specific to the U.S. and as you've noted, the laws vary by jurisdiction.

For accidents that happen in Florida, PIP can covers other people who drive your car but with your permission. For those accidents that happen inside the U.S. or Canada, PIP only covers you and relatives who lives with your in the same house. But in this case, you must be driving your own vehicle.

If you have written permission of deicing someone Else's vehicle then PIP keeps you covered..

I'll keep that in mind. Never know when I might decide to deice someone else's car.
