The mandatory insurance is for your liability if you damage other people’s property. (If you have financed the car, you likely also have to insure your own car against collision and other damages, but that’s a condition of the financing, not a law.) We were hit from behind in a car that we did not carry collision insurance on. The at-fault driver is responsible for the repairs and they have mandated insurance to cover that.
