Idaho Car Insurance Requirements
Idaho requires all drivers to carry liability insurance. The minimum coverage levels are:
- $25,000 bodily injury liability per person
- $50,000 bodily injury liability per accident
- $15,000 property damage liability per accident
This is commonly written as 25/50/15 liability.
No uninsured motorist requirement: Idaho does NOT require uninsured motorist (UM) coverage, but experts strongly recommend adding it. About 9% of Idaho drivers are uninsured. Without UM coverage, you could be left with nothing if hit by an uninsured driver.
Idaho is a tort state, meaning the at-fault driver is financially responsible for injuries and damages they cause.
Why You Should Add Uninsured Motorist Coverage
Although Idaho doesn't require uninsured motorist (UM) coverage, it's one of the most important coverages you can buy:
About 9% of Idaho drivers are uninsured. If one of them causes an accident, your UM coverage pays for your injuries and damages. Without UM, you'd have to sue the at-fault driver personally—and may never collect.
UM also covers hit-and-run accidents. If you're injured by a hit-and-run driver who flees the scene, your UM coverage pays.
Recommended UM limits: At least 100/300 to match standard liability coverage. The cost is modest—typically $50-$100/year—compared to the protection it provides. Also consider adding underinsured motorist (UIM) coverage for drivers who don't have enough insurance.
Average Car Insurance Costs in Idaho
Idaho drivers pay an average of $1,244 per year for full coverage car insurance, or about $104 per month. This is well below the national average of $1,771/year. Minimum coverage in Idaho averages around $456 per year.
Idaho has some of the lowest car insurance rates in the nation thanks to: lower population density, fewer accidents per capita, less traffic congestion, lower theft rates, and lower cost of living.
Rates vary by city and region:
City rate examples (average full coverage):
• Boise: $1,312/year (highest in Idaho)
• Meridian: $1,289/year
• Nampa: $1,256/year
• Idaho Falls: $1,187/year
• Pocatello: $1,198/year
Boise has the highest rates due to higher traffic density, but even Boise is affordable compared to most U.S. cities.
Rural Driving and Coverage Considerations
Idaho has vast rural areas with unique insurance considerations:
Wildlife collisions: Deer, elk, and moose are common on Idaho roads. Comprehensive coverage covers animal strikes. Idaho drivers hit a deer or elk more frequently than most states.
Long distances to help: Roadside assistance is valuable in rural Idaho where tow trucks may be 50+ miles away. Many insurers offer this for $10-$30/year.
Winter weather: Idaho experiences harsh winters with snow and ice. Comprehensive covers weather damage; collision covers accidents caused by icy roads.
Mountain roads: Parts of Idaho have steep, winding mountain roads. Collision coverage is important if you regularly drive these routes.
Wildlife tip: If you're about to hit a deer or elk, don't swerve—maintain your lane and brake firmly. Swerving often causes worse accidents. Animal strikes are covered by comprehensive, but swerving into a ditch or oncoming traffic may complicate your claim.
Idaho Financial Responsibility Law
Idaho law requires all drivers to maintain proof of financial responsibility. You must carry proof of insurance in your vehicle at all times. Acceptable proof includes:
- Physical insurance card
- Digital insurance card on your phone (Idaho accepts electronic proof)
- Electronic policy document
Penalties for driving uninsured in Idaho:
• $75 fine for first offense, up to $1,000 for repeat offenses
• Driver's license suspension
• Vehicle registration suspension
• SR-22 requirement
• Possible jail time for repeat offenses
• Higher insurance rates when you reinstate coverage
SR-22 Insurance in Idaho
An SR-22 is a certificate your insurer files with the Idaho Department of Transportation proving you carry liability insurance. Idaho requires SR-22 after:
- DUI or DWI conviction
- Driving without insurance
- Multiple at-fault accidents or serious violations
- License suspension or revocation
- Accumulating excessive points on your record
The SR-22 filing fee is typically $15-$50, but your insurance rates will increase significantly—often by 50-100%+.
How long? Idaho typically requires SR-22 for 3 years. You must maintain continuous coverage—any lapse triggers license suspension.
Coverage Options Beyond the Minimum
Consider adding these coverages beyond Idaho's minimum:
Higher Liability Limits: Increase from 25/50/15 to 100/300/100 or higher. Recommended: At least 100/300/100 to protect your assets.
Uninsured/Underinsured Motorist (UM/UIM): NOT required but highly recommended. Recommended limits: Match your liability coverage (100/300).
Collision Coverage: Pays for damage to your car after an accident, regardless of fault. Recommended if: Your car is worth more than your deductible or you have a loan/lease.
Comprehensive Coverage: Essential in Idaho for deer/elk strikes, weather damage, theft, and vandalism. Highly recommended.
Rental Reimbursement: Covers rental car costs while your vehicle is repaired. Typical cost: $20-$40/year.
Roadside Assistance: Important in rural Idaho. Typical cost: $10-$30/year.
