Yes, almost every car insurance company provides low mileage insurance to drivers. If the driver drives less than the national average mileage or the average mileage decided by the company then he or she can get a discount.
The discount amount and its conditions can vary from company to company. As a result; it is better to clear this with your company before purchasing the policy.
Low mileage insurance entirely depends on how much you are driving. If you are someone who works from home or uses public vehicles more than your private car then this can be beneficial for you.
But if you are dependent on your car for everything like; work, grocery shopping, Sunday outing, picking up your kids, etc. Then low mileage insurance can not help you to save money.
