Liberty Mutual ByMile®

Liberty Mutual’s new low-mileage driver program, ByMile, gives you the flexibility of only paying for the auto insurance you need. All the coverage of a traditional auto policy, but at a fraction of the price because your rates are customized based on the number of verified miles you drive.

Auto insurance for low-mileage drivers

The small ByMile device tracks the number of miles you drive, so your monthly bill will be based on how many miles you drove in a prior month. Your bill will change each month, but you will never be charged for more than 150 miles per day.
