Idaho requires all drivers to carry minimum liability insurance of 25/50/15 (Bodily Injury per person / Bodily Injury per accident / Property Damage):
Idaho is a tort state with relatively affordable auto insurance rates, consistently ranking among the lower-cost states in the country. The state's low population density, modest litigation rates, and rural character all contribute to a favorable claims environment. Required minimums of 25/50/15 are low by national standards, and the competitive market allows drivers willing to shop around to find very reasonable rates for robust coverage.
Rural driving in Idaho carries its own set of risks that urban-centric insurance shoppers may underestimate. Long distances between towns mean that accidents can occur far from emergency services, potentially increasing injury severity. Deer and other wildlife collisions are common on state and federal highways, making comprehensive coverage valuable even for older vehicles. In northern Idaho and mountain communities, winter driving conditions create elevated accident frequency during the extended snow season.
