State Requirements

Idaho operates under a tort-based liability system where the at-fault driver is financially responsible for damages. Drivers must carry proof of insurance at all times and present it upon request by law enforcement or after an accident. The Idaho Department of Insurance enforces these requirements through an electronic verification system that flags uninsured vehicles for registration suspension.

Idaho cityscape and street view
25/50 ($25,000 per person, $50,000 per accident)
Bodily Injury Liability
Covers medical expenses, lost wages, and legal costs when you injure someone in an at-fault accident. Idaho's minimum of $25,000 per person is frequently insufficient — a single emergency room visit and ambulance transport can exceed this limit. Idaho law allows injured parties to sue for damages beyond your policy limits, putting your personal assets at risk.
$15,000 per accident
Property Damage Liability
Pays for damage to another person's vehicle or property when you cause an accident. The state minimum of $15,000 falls short when you total a newer vehicle — the average new car price in Idaho exceeds $40,000. Rural Idaho drivers who strike livestock, fencing, or irrigation equipment face particularly high property damage claims that quickly exceed minimum limits.
Not required (must be offered)
Uninsured/Underinsured Motorist Coverage
Protects you when hit by a driver with no insurance or insufficient coverage to pay your damages. Idaho law requires insurers to offer this coverage at the same limits as your liability policy, but you may reject it in writing. With approximately 7% of Idaho drivers uninsured — concentrated in rural counties — this coverage addresses a measurable gap in the state's insurance compliance.
Not required
Personal Injury Protection
Covers your medical expenses and lost wages regardless of fault. Idaho does not mandate PIP, unlike no-fault states. Drivers without health insurance or with high-deductible plans should consider adding this coverage, particularly those who commute on Idaho's rural highways where medical response times average 15–25 minutes.

Cost Overview

Idaho insurance rates reflect the state's mix of urban density in the Treasure Valley and expansive rural counties with limited emergency services. Drivers in Boise and Meridian pay 20–30% more than those in rural areas due to higher collision frequency and vehicle theft rates. Winter driving conditions — Idaho averages 40–60 inches of snowfall in mountain corridors — elevate comprehensive and collision claim frequency statewide.

What Affects Your Rate

  • Boise drivers pay $125–$165/month on average compared to $90–$115/month in Twin Falls, reflecting urban collision density and theft rates.
  • Winter weather claims — Idaho processes 35–45% more comprehensive claims November through March due to ice damage, wildlife collisions, and road debris.
  • Rural highway driving increases rates 10–15% in counties like Custer and Lemhi where average emergency response times exceed 20 minutes.
  • Wildlife collision frequency — Idaho ranks among the top 10 states for deer strikes, with over 2,000 reported annually, directly impacting comprehensive premiums.
  • Credit-based insurance scoring affects Idaho rates significantly, with poor credit increasing premiums 40–70% compared to excellent credit.
  • Young drivers under 25 pay $210–$290/month for full coverage, nearly double the state average, particularly in Ada and Canyon counties.

Coverage Types

Liability Insurance

Idaho's required 25/50/15 minimum coverage pays for injuries and property damage you cause to others. Most drivers benefit from increasing limits to 100/300/100 to protect assets in serious accidents.

Full Coverage

Combines liability, collision, comprehensive, and uninsured motorist coverage into complete protection. Covers your vehicle regardless of fault and protects against Idaho-specific risks like wildlife and winter weather.

Comprehensive Coverage

Pays for non-collision damage to your vehicle including theft, vandalism, hail, fire, and animal strikes. Deductibles typically range from $250 to $1,000.

Collision Coverage

Covers damage to your vehicle when you hit another car or object, or when you roll over. Required by lenders on financed vehicles.

Uninsured Motorist Coverage

Protects you when hit by a driver with no insurance or insufficient coverage. Idaho requires insurers to offer this but allows drivers to reject it in writing.

SR-22 Insurance

An SR-22 is not insurance but a certificate proving you carry state-minimum coverage, filed by your insurer with the Idaho DMV. Required after DUI, multiple violations, or driving uninsured.
