Typically insurance companies will offer insurance for terms of 6 or 12 months and not shorter periods of time. It could be possible to purchase this insurance and then cancel the policy when it is no longer needed. This may result in cancellation fees and need paperwork filed out properly to make sure the cancellation takes place.

You might have a problem getting auto insurance though if you do not have a Montana license since some companies will not write policies if you only have an international permit. If you have a Montana license and are looking for insurance you can contact us.

If this option does not work you can buy the insurance available at that the rental car agency offers.
