State Farm dropped my road towing because I used it 3 times a year for the last 3 years, and raised price for 6 months from $68 a month to $80! Legal?

Auto insurance companies offer emergency roadside assistance services to their customers at a nominal fee presuming it will be used lightly. If the insurance company feels the service is being used excessively they do have the right to drop the roadside assistance coverage unless you can provide them with evidence that you have resolved the problem. An example is that if you had to get a jump start several times if you show you purchased a new battery, they may be willing to continue the coverage. The renewal premium does not have any connection to the dropping of the roadside assistance benefits. The losses for roadside assistance service are not able to be rated, and cannot be used as a rate adjustment for auto insurance premiums. It is probable that there was a rate change made by the insurance company recently and it affected you at the renewal. You should contact your agent to explain the rate increase for you auto insurance policy and see if there is some way you could reduce your pocket costs through the level of coverage adjustment, increased deductibles, or find additional discounts.
