Stretching from Canada in the north to Nevada and Utah in the south, Idaho is 479 miles from top to bottom. It's big enough that it takes two states – Washington and Oregon – to fill the same space on the map to the west. Many Idahoans end up needing cars and trucks to get around in those wide-open stretches. That’s obvious when you look at the numbers. The state’s roughly 1.75 million residents are responsible for some 1.7 million registered vehicles, including 1.3 million passenger vehicles. 

This is a lot of vehicles to insure, and Idaho’s Office of Highway Safety helps explain why coverage is so important. It turns out that there are approximately 25,000 motor vehicle crashes each year in Idaho. Separate data from the FBI Uniform Crimes Report shows that the number of cars stolen in Idaho had recently topped 1,600 vehicles per year. Idaho drivers also face the risk of wildfires and flooding, which can have a major impact on insurance needs.

The good news is that the state has some of the lowest average insurance representative rates in the country for 2019. Comparing the same hypothetical driver profile in both cases, the Gem State’s average annual automotive insurance cost in our analysis is $371 lower than for the nation as a whole. The flipside to this is a national average that’s nearly 40% higher than the Idaho average. 

A few key elements go into the Idaho rates. For instance, car insurance costs are generally highest for the youngest drivers, since they get into the most accidents. It makes sense, as most of these drivers don’t have a lot of time behind the wheel when they first get their licenses. Rates come down as you get older and more experienced. And in Idaho, there are quite a few older and more experienced drivers to get those lower rates and bring down the state’s average. In fact, citizens aged 65 and above make up the largest percentage of the Idaho’s drivers. Commuting times can be another vital consideration for insurance rates, as this reflects how long you spend driving in traffic. Idaho shines here because its largest city, Boise, is in the U.S. top 10 for shortest commutes. That said, smaller cities may have even lower rates since insurance tends to cost less in places with a lower population density. 

Boise’s Ada County is home to nearly 400,000 registered vehicles, which is close to 25% of all vehicles registered in Idaho in total. Yet nearly half of all Idaho counties have 15,000 registered vehicles or fewer.

Cheapest Car Insurance Companies in Idaho

The rates shown here are based on a study performed by Quadrant Information services on behalf of U.S. News. The study examined rates from nine largest car insurance companies in the United States, using certain driver profiles. Your rates will differ.

How We Found the Cheapest Car Insurance in Idaho

At U.S. News, we’re all about helping people make life’s important decisions. Our college rankings, launched in 1983, set the standard in educational rankings. Our ranking in other fields, like healthcare, government, and the automotive sphere, help people and thought leaders make choices that make lives better. Now we’re continuing to empower you with the information you need to make the right choices for your life with our Cheapest Car Insurance Rankings.

Our Study Rates

For this study, U.S. News worked with Quadrant Information Services to analyze a report of insurance rates in all 50 states from the 10 largest national car insurance companies, though not every company operates in every state Quadrant obtained publicly available rate data that car insurers file with state regulators. Our study rates are based on profiles for both male and female drivers aged 25, 35, and 60. Vehicles used include the 2015 Honda Civic, 2015 Toyota RAV4, and 2015 Ford-F-150, with annual mileage ranging from 6,000 and 12,000. 

Three car insurance coverage levels were used, as were credit tiers of good, fair, and poor. Clean driving records and records with one accident, one speeding violation, and one DUI were also used in the calculations of certain driver archetypes. To get the state-wide study rates shown here, we computed the mean rate for male and female drivers ages 25, 35 and 60 who drive 12,000 miles per year, have medium coverage, good credit and a clean driving record. The rates shown here are for comparative purposes only and should not be considered “average” rates available by individual insurers. Because car insurance rates are based on individual factors, your car insurance rates will differ from the rates shown here.

How Much Does Car Insurance Cost in Idaho?

Idaho is a great place for car lovers, thanks to average insurance rates in our study that rank fifth-lowest in the country. A typical policy for our Idaho driver profiles costs on average $952 per year in 2019. There was a fair amount of difference in the individual companies' study rates, though.

USAA checked in with by far the lowest representative quote of the eight insurers in our Idaho comparison: $568. The study rate from the next cheapest company, Travelers, was $673. Allstate was at the opposite end of the spectrum. Annual coverage from that company required $1,389. Also topping $1,000 per year in average insurance expenses, according to our analysis, were Nationwide and American Family, with rates of $1,180 and $1,134, respectively.

True, those are all sample policies, drawn from carefully constructed driver profiles. Yet they’re a good indication of how variable costs can be in Idaho.

Idaho Car Insurance Rates by Age

Among the most influential factors on insurance coverage come from your personal demographics. Age and gender are particularly important, and they work together to affect how much you pay for auto insurance everywhere. To see how this plays out in Idaho, we developed a series of standardized driver profiles that were based on men and women at three age levels. The profiles had good driving records and drove 12,000 miles annually. We took into account vehicle types by setting up profiles for the same drivers in a 2015 Honda Civic car, a 2015 Toyota RAV4 crossover, and a 2015 Ford F-150 pickup. Every one of our hypothetical drivers had good credit, too, along with a medium level of insurance coverage. 

The bottom line was that the biggest difference in rates came at the youngest age level. When both profiles are for 25-year-olds, the male driver profiles paid an average rate in our study of $1,139 for car insurance in Idaho, while the average representative cost for the female profiles was $1,090. That’s an advantage of about $50 for the female profile. But when we researched male and female driver profiles at the age of 35, the average study rate for the male profile – $914 – was just $3 above that for the female profile. Representative rates began diverging again with the profiles at 60 years old. At that point, female driver profiles paid $820, while the male profiles have a study rate of $838.

Idaho Car Insurance Rates by Credit Score

To see the effect of credit scores on insurance costs, we created a series of similar driving profiles for men and women who had good, fair, or poor credit. All profiles represented customers who drive 12,000 miles a year, have a clean driving record, and are shopping for medium levels of insurance. Digging deeper, we also ran the same profiles for people at 25, 35, and 60 years of age, and when they’re driving a 2015 Honda Civic, a 2015 Toyota RAV4, and a 2015 Ford F-150.

The results showed that the average insurance rate in our study for a driver profile with good credit was $952.10. Slipping to a fair credit score adds almost $150 to that total. If a profile had a poor credit rating attached, the average representative cost of insurance climbed to $1,591.

Idaho Car Insurance Rates by Driving Record

Insurance companies generally believe that the best way to predict the future is by studying the past, so your driving history is a major factor in determining auto insurance rates. For our Idaho driver profiles, it only takes a single speeding ticket for the average cost of insurance in our study to spike by $288 per year. With an accident on our profile's driving record, the average representative rate jumps from $1,240 to $1,454. As an example of a more serious offence, a conviction for driving under the influence (DUI) raised the average annual cost of car insurance in our analysis in Idaho to $1,786. 

These study rates are drawn from our curated driver profiles for men and women at ages 25, 35, and 60. Our profile criteria also include good credit scores, medium levels of coverage, and 12,000 miles of annual driving in three vehicles: a 2015 Honda Civic, a 2015 Toyota RAV4, and 2015 Ford F-150 pickup.

Idaho Car Insurance Rates by Coverage Type

Of course, not all drivers want the same amount of insurance protection. With that in mind, we also varied our profiles by high, medium and low coverage levels. What we kept the same were details such as having both a good credit score and an accident-free driving record. Also in place was our 12,000-mile annual driving limit with 2015 model-year examples of the Honda Civic, Toyota RAV4, and Ford F-150. 

In terms of personal characteristics, our sample rates averaged the data from female and male driver profiles represented as 25, 35, and 60 years old.

It’s no surprise that the least expensive average study rates are for the lowest amount of coverage. However, the differences aren’t really that noticeable. Going from low to high coverage increased insurance costs by less than $60 a year according to our study.  That means you may want to think twice before reducing your coverage as a way of cutting your budget. After all, you may be saving $5 per month in premiums, but you could have to pay thousands of dollars in damages if you get into an accident with the minimum legal amount of insurance.

Idaho Car Insurance Rates by Annual Mileage

Our analysis indicated that how far you drive may not make a significant impact on rates either. We found that that the average annual insurance premium in our study was $916 when driving 6,000 miles a year in Idaho. Doubling that distance only bumped the representative rate up to $952. This is a change of about 4%.

Note that these rates are for illustration purposes only. They are based on driver profiles for 25-, 35- and 60-year-old men and women with a clean driving history and good credit records. To further expand our sample size, profiles were created for a medium level of insurance on a trio of popular vehicles: the 2015 Ford F-150, 2015 Toyota RAV4, and 2015 Honda Civic.

Idaho Car Insurance Rates by City

Urban living offers its share of advantages, but they don’t include inexpensive insurance coverage. Crowded city streets can lead to more opportunities for accidents, and crime rates are usually higher in cities as well. Both conditions will drive up the price of insurance. On the other hand, the lowest average insurance representative costs in Idaho’s cities were in relatively large places like Boise ($872) and Meridian ($866). The same insurance policies in our study cost more in smaller metro areas like Idaho Falls ($977) and Lewiston ($959). 

That outcome is the result of getting quotes for our comprehensive series of custom driver profiles. They allowed us to see statistics for male and female drivers with no accidents on their driving record and no problems on their credit scores. The vehicles used for our research were the 2015 Toyota RAV4, 2015 Ford F-150, and 2015 Honda Civic. In all scenarios, we assumed drivers were covering 12,000 miles annually and had a medium level of insurance coverage. We also broadened our database by developing sample profiles for drivers who were 25, 35, and 60 years old.

Idaho Auto Insurance Minimum Coverage Requirements

Idaho stands out as one of the states where you don’t need traditional third-party auto insurance coverage. Instead, drivers can post an indemnity bond that’s basically a personal promise to pay for damages. This option requires a guarantee of least $50,000 per accident, with $15,000 of that amount allotted for property damage. Idaho caps payments at $120,000 in property damages in situations where five or more vehicles are involved.

If you would rather go the conventional route with an insurance company, Idaho has the following requirements:

  • Bodily injury coverage: $25,000 per person, $50,000 per accident 
  • Property damage coverage: $15,000 per accident 

Drivers who have had their licenses suspended in Idaho may also need to get an SR22 certificate before reinstatement. It’s a document filed by an insurance company that supports your proof of financial responsibility.

We established which companies have the lowest average insurance representative rates in Idaho by comparing prices for a wide span of drivers. Included were sample profiles for women and men, all with clear driving histories. Additionally, we ran the profiles for drivers at three ages – 25, 35 and 60 – and with a medium level of insurance coverage. We held credit scores constant at “good” in each situation, while limiting miles driven to 12,000 per year. As for what was driven, our vehicle examples were the 2015 Toyota RAV4, 2015 Ford F-150 and 2015 Honda Civic.

The final rankings saw the USAA setting the pace for low-cost Idaho insurance with an average rate in our study of $568. Because that company focuses on coverage for military members and their families, we’ll also point out that Travelers – with a broader customer base – had the next least-expensive coverage: $673 each year. The costliest coverage was a $1,389 representative policy from Allstate. 

Why Car Insurance Rates Vary in Idaho

Insurance companies are in business to make a profit. This usually means taking in more money in premiums than they pay out in claims. Our driver profiles put that into focus. They charged higher insurance rates in our analysis when it seemed more likely that they would have a claim during the policy term. Red flags for insurers include: 

  • Younger drivers, who may not have the experience to avoid an accident. 
  • Drivers who live in cities, since the higher amounts of traffic and crime can lead to more potential for vehicle damage.
  • People who have gotten into accidents in the past, as statistics show they tend to get into more accidents in the future.
  • Drivers with bad credit scores, because insurers take this as a sign of financial irresponsibility.

Conversely, older drivers with clean records, a good credit history, and an address in a smaller town or village have proven to be less risky for companies to insure. These people are charged less for coverage as a consequence.

How to Get the Cheapest Car Insurance in Idaho

Almost any driver, regardless of things like credit score or driving history, can still save some money on car insurance. One method is to comparison shop. Remember, according to the statewide average rates in our study, switching from the priciest coverage to the cheapest would deliver an annual savings of more than $820.

Insurance companies also offer an extensive range of discounts. Now, this does include savings that showed up already in our study – such as discounts for accident-free driving and good credit scores. But it’s common for insurers to go beyond this. They can offer lower costs when you bundle all your insurance needs with one company, pay your premiums twice a year instead of monthly, or get coverage for students with good grades. Organizations ranging from credit unions to college alumni associations partner with insurance companies as well. By harnessing the buying power of all members, the groups can arrange lower policy costs. 

Drivers who are especially careful can save money with an in-vehicle tracking device from certain insurance companies. The insurers use real-world data from those devices to determine their pricing. 

Additional discounts are sometimes available if you take a qualified driver-education class. The key here is to make sure the cost of the class is less than the discount you get. Otherwise, you won’t actually save any money on the deal.  

Important Laws Around Auto Insurance in Idaho

Idaho is an at-fault state, so each person involved in an accident is responsible for damages from their own negligence. You can think of it like this: If you are in an accident and someone files a claim against you, the court will make a finding about who is responsible for what percentage of the crash. If it turns out that the other person was 25% responsible, the amount of damages awarded to that person will be cut by the same percentage.

Idahoans can post an indemnity bond of $50,000 instead of buying a traditional insurance policy.

As a nod toward the changing times, physical insurance cards are no longer necessary in Idaho. A digital card that you show on your smartphone is now acceptable.

Idaho Driving Laws and Punishments

Texting while driving is prohibited in Idaho, but it’s categorized as a “civic public offense,” not a “crime.” So you cannot be arrested for texting and driving in the state or forced to post bail. Nor is it considered a moving violation for purposes of increasing insurance rates. The punishment is a fine, and if you don’t pay up, your license can be suspended. Moreover, this only applies to drivers caught texting with a handheld device. Using a car’s hands-free, voice-activated technology to send and receive texts while driving is allowed.

Drinking and driving is treated more seriously. If you are 21 or older, you can be charged with driving under the influence (DUI) if you have a blood alcohol concentration (BAC) of .08% or higher. Younger drivers can be charged for having a BAC of .02%. Idaho also increases penalties if children are in the vehicle, if the driver’s BAC is above .20%, or if a driver has been convicted of a past DUI.

The maximum penalty for a first offense is six months in jail and/or a $1,000 fine, plus having your license suspended for 180 days. In a worst-case scenario, a conviction for “aggravated DUI” could lead to 15 years in prison, a suspended license for five years, and/or a fine of $5,000. 

Idaho takes an interesting approach to handling situations with uninsured motorists (UM). On one hand, any policy offered in the state must include UM coverage for bodily injuries. This is to protect the insured driver in a case where another person is liable for damages but doesn’t have his or her own insurance to pay for it. The thing is, you can sign off to reject UM coverage in Idaho if you don’t want to carry it. Idaho doesn’t have similar requirements for UM property damage.
