Idaho Car Insurance Requirements

Minimum Coverage Requirements

Idaho requires drivers to carry minimum liability insurance of 25/50/15 — meaning $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $15,000 for property damage. PIP coverage is not required in Idaho, though it may be available as an optional add-on. These are the legal minimums; most insurance professionals recommend carrying significantly higher limits to protect personal assets in a serious accident. A common recommendation is at least 100/300/100, which provides substantially more protection without a proportionally large premium increase.

Average Car Insurance Costs in Idaho

Drivers in Idaho typically pay approximately $960 per year ($80/month) for car insurance, based on 2026 industry average data.

Drivers with clean records may see rates well below the state average, while those with violations, claims, or high-risk profiles may pay substantially more.

State Regulations and Key Rules

Idaho is an at-fault state with one of the lowest average car insurance premiums in the nation. Uninsured motorist coverage must be offered but can be rejected. The state's rural character and low traffic density contribute to lower rates.

What Makes Idaho Unique

Idaho consistently ranks among the cheapest states for car insurance, largely due to low population density, fewer accidents, and lower vehicle theft rates.

Uninsured Drivers in Idaho

Approximately 8.8% of drivers in Idaho are estimated to be uninsured. Carrying uninsured and underinsured motorist coverage provides important protection against the financial impact of an accident with an uninsured or underinsured driver. Uninsured motorist (UM) coverage pays for your medical expenses and vehicle damage if you are hit by a driver without insurance or with insufficient coverage. Underinsured motorist (UIM) coverage fills the gap when the at-fault driver's policy limits are too low to cover your losses.

Risk Factors Specific to Idaho

Deer and elk collisions are among the most frequent comprehensive claims in Idaho, particularly in northern and eastern regions. Mountain pass closures and black ice are significant winter hazards. Wildfire smoke in summer can reduce visibility.

How to Save on Car Insurance in Idaho

Idaho's already-low rates can be pushed lower with multi-policy bundling and good driver discounts. Many rural Idaho drivers benefit from paying annually rather than monthly to avoid installment fees. Comprehensive coverage for deer collisions is highly recommended statewide.

• Compare quotes from at least 3–5 insurers annually — rates for identical coverage can vary by hundreds of dollars.
• State minimums are typically insufficient for serious accidents — consider liability limits of at least 100/300/100.
• Ask about bundling discounts if you also need home or renters insurance.
• Consider telematics or usage-based insurance if you drive fewer miles than average or primarily drive during off-peak hours.
• Review your coverage annually, especially after major life changes: moving, buying a new vehicle, or adding a teen driver.
