There are some regional carriers that can provide short-term car insurance. This is used when someone is borrowing a friends car, or for a long term rental.
I do not recommend purchasing a six month policy then cancelling it after one month. The reason I don't recommend this is that insurance companies want to know if you canceled a policy early on applications. If you are applying for insurance in the future and answer honestly (which you should do), then it will cause your rates to go up, or could cause the underwriters to decline your risk.

I hope this helps.
