If you own a car, one way to get car insurance for less than six months is to buy car insurance and cancel it early. You can typically cancel your policy before the six-month mark and get a refund for the unused months. A three-month policy in Montana costs an average of $304.
Rental car insurance might be the best option for drivers renting a car in Montana or non-owners who need to drive around Montana.
MoneyGeek also looked into other scenarios that might require drivers to get temporary car insurance, like if you need to purchase non-owner insurance for license reinstatement or if you work for a ridesharing company.
