A closer look at car insurance in Idaho
Idaho's rock-bottom pricing makes full coverage easy to justify — the gap to a minimum policy is small. The 25/50/15 minimum is low relative to modern repair and medical costs, so higher liability limits are inexpensive insurance here. With credit and location still creating differences between carriers, a quick comparison can shave even more off an already-low Idaho rate.
Bottom line
Idaho is one of the most affordable states for car insurance. Because full coverage costs so little more than the minimum, most drivers should carry it — and compare a few carriers to push the rate lower still.
