Insurance rates have been on a steady rise for the past 12 plus months, primarily due to the cost of repair & replacement. Auto parts have been on the rise since 2020 & have not leveled off, likewise with building materials. Issues with supply & demand are part of the reason for prices on the constant rise not to mention increased labor rates. Employers are having to pay more to attract employees as well as keep those they have, especially in the construction sector. This is a sick cycle that we are stuck in no doubt. It seems to me that most insurance companies have been raising rates, some not as drastic as others, so my recommendation to you would be to shop for apples to apples coverage as well as possibly consider some coverage changes to your existing coverage, specifically to the deductibles on the physical damage coverage on the vehicles. Consider higher "Broad Form" Collision deductibles, with broad form collision, as long as you are not at fault, the deductible does not apply. Consider higher comprehensive deductibles, perhaps with a waiver of glass deductible option if you are prone to windshield loss. Another thing to look at is the vehicle that your 17 y/o is assigned to drive. I would recommend putting that driver on your lowest rated vehicle, preferably, on one that requires liability only as youthful drivers on vehicles with "full coverage" is extremely costly.
