In the state of Washington what happens when invalid auto insurance is given at the scene of a minor traffic accident?

We’re traveling to England in May – I’ve never bought travel insurance and want to know how we find good/reliable insurance? Thanks.

I have looked at a few insurance websites and they all seem to say the insurance must be obtained within 15 days of travel booking. Well, I paid for the trip in January and it’s for late July. I had no idea I’d need to get insurance my mid-February. Does anyone know of any travel insurance companies without this requirement?
Sorry, I forgot to add: I’m in the U.S.A.

Im thinking about getting veneers when I return home from my deployment, and tricare prime doesn’t cover cosmetic dentistry. What kid of health insurance do I need to actually get the procedure done?

I am a foreigner living in the US, so I could not buy any travel insurance that requires US residency. This summer, I will be traveling back to my home country on a business trip. I am for looking for a type of insurance that could cover my time both in my home country and during my round trip flight. Thank you very much!
