Can i get a car insurance policy for a month ONLY?

my friends and i are planning a road trip across the country and back. my friends grandma just got a new car and has her old car just sitting in her driveway. we want to take it because its a four door car but it has no insurance policy.
is there anyway to get coverage for the month we are gone ONLY and not for the whole year or 6 months, or 3 months.

thanks
