In NYS you also have to maintain liability insurance as long as registered, no lapses as MrCoupe said. The NYS DMV website describes a process where you have to remove the registration and inspection sticker's then remove plates and surrender at DMV --- then you can cancel insurance. I don't think insurance companies will cancel insurance without the DMV paperwork.
Here in NYS ...
the DMV offices are closed, so I can't surrender my plates therefore I can't cancel my liability insurance. Catch 22. I'm forced to pay for insurance I will not use.

Not the end of the world, worse things are happening. Just another SNAFU.
Something I thought about and had to figure out, hate to waste money.
My buddy works with Andrew Cuomo on a NYS task Force.
I'm throwing this situation over to him as an "idea".
Cuomo could issue short term direction to relax some of these rules.
That's where we are these days, extraordinary times require new modes of operation.
Kind of doubt they will relax this requirement.
Too much risk of people driving around without insurance.
Life is always a balance of one thing against another.
