Car insurance rates in Idaho by city

Cheapest car insurance in Idaho

Auto-Owners is often the cheapest option for car insurance in Idaho.

Insurers consider a wide variety of factors when setting a premium including your driving record, credit score, age and marital status as well the vehicle. Where you live also affects rates.

“States that have a higher rate of severe weather that damages cars or helps cause accidents will typically have higher rates,” says Chong Gao, director of product management R&D at Mercury Insurance. “Florida, for example, is prone to extreme weather like hurricanes and its car insurance costs are consequently much higher.”

Insurance companies crunch all this data with proprietary algorithms, which can result in dramatic differences in premium quotes.

The numbers highlight these differences. Allstate is the most expensive insurer in Idaho with an average premium of $1,945 a year.

On the other hand, as mentioned above, the average premium for Auto-Owners policyholders in Idaho is $916 a year. State Farm had the second cheapest coverage in Idaho at $1,120 and Geico rounded out the top three cheapest at $1,174.

Full coverage car insurance in Idaho

As noted, the rates above are for full coverage car insurance. Residents of Idaho will often be advised to get full coverage, which includes both liability protection as well as collision and comprehensive. Liability helps pay medical and legal bills for injuries or damages you are responsible for after an accident. However, liability doesn’t cover damage to your vehicle or your injuries.

Collision will pay to repair your vehicle if it is damaged after colliding with another vehicle or object. Comprehensive covers perils such as fire, theft, flooding, vandalism and more.

Shopping for car insurance in Idaho

Shopping around for coverage is a great way to make sure you are getting the best rates on your auto insurance. Experts often tell consumers to shop for insurance yearly. But that doesn’t necessarily mean you should be looking to switch.

“I recommend that people stay with the same insurance company, as they tend to get a better rate when they have been with the same carrier for more than 12 months. The more tenure you have with a carrier, the more potential there is to earn benefits,” says Tim Bottini, a Country Financial insurance agent based in St. Louis. “The carrier can also review your claims history and provide information about applicable discounts.”

But make sure you are comparing like coverage levels and deductibles.

“It is extremely important to make sure you start off with an apples-to-apples comparison,” Bottini says. However, if a person has low limits, say 25/50/25 – limit per person/per occurrence/limit for property damage – he will recommend higher coverage.

“Depending on their age/income and profession,” he says, “I would quote higher limits to protect their net worth and earnings potential.”

Bottini also says people can save money on their car insurance by keeping their credit score up, following the speed limit and placing both home and auto insurance with the same carrier.

Cheapest car insurance in Idaho by age

Car insurance rates will vary by age as reams of statistics show that teen and young adult drivers, because they are inexperienced on the road, take bigger risks and are more likely to get in an accident and file a claim, which is why they pay more for coverage than older more experienced drivers.

Auto-Owners turned out to be the best insurer in Idaho for drivers of all ages. The numbers show the difference between young and old drivers with the lowest premium for a teen coming in at 91% more than the lowest premium for a senior driver.

Once a driver hits 25, rates will start to drop, assuming they keep their driving record clean, and will stay stable until their 70s when they will start climbing a bit.

Cheapest car insurance for senior drivers in Idaho

According to our data, senior drivers pay roughly 31% more than middle-aged drivers.

Seniors tend to pay slightly higher car insurance rates than younger drivers. In Idaho, the cheapest insurance company for senior drivers is Auto-Owners at $973 a year or $81 a month. State Farm grabbed the second-place spot with premiums running $1,085 annually or $90 a month, Nationwide was third at $1,404.

Seniors pay higher rates thanks to age-related issues. They often suffer from vision and hearing issues as well as slowing reflexes and medical issues. This all leads to more accidents and claims, which pushes up the cost to insure seniors.

The chart below shows the average premium for senior drivers.

Car insurance for young drivers in Idaho

While rates start to drop for teen drivers as they become young adults, they still pay slightly higher rates than more experienced drivers. According to our data, Auto-Owners is the cheapest insurer for drivers in their early 20s with an average premium of $1,659 a year or $138 per month.

Travelers was the second cheapest insurer at $1,848 and State Farm will insure a young driver in Idaho for $1,899 a year.

State Farm was second most affordable at $3,306 a year or $276 monthly while Geico was number three at $3,663.

While teens are expensive to insure, there are a few ways to save some money. Most insurers offer a good student discount so if your teen is carrying a B average or above you should ask for a discount. Putting them in an older vehicle will also lower your insurance costs.

Average cost of car insurance in Idaho

The average cost of car insurance in Idaho is $1,428, which makes it the 47th most expensive state in the country behind Louisiana and Florida.

Metropolitan areas – and all states have them – equals lots of drivers, which often leads to car crashes and claims.

“States with a higher population density have more cars on the road and thus more accidents and claims, increasing insurance rates. A more rural state like Iowa will have significantly lower average yearly car insurance costs compared to a highly metropolitan state like Idaho,” says Gao.

Below is the average rate in each state for a 40-year-old driver of a 2023 Honda Accord LX.

Cheapest car insurance for high-risk drivers in Idaho

If you have an incident on your driving record, you may be considered a high-risk driver, and you will pay more for coverage. A speeding ticket, at-fault accident, or DUI can send your premium skyrocketing.

When we ran the numbers, we found that a speeding ticket in Idaho will push the average rate to $1,285 and an at-fault accident will push it to $1,497.

An accident will stay on your record for at least three years so you will be paying a higher premium for quite a while after an accident.

A DUI will usually result in a massive increase and could push your premium into unaffordable territory. If you are convicted of a DUI, your rate on average will climb to $2,138 a year. A DUI will be reported to insurers for three years, and if you are a commercial driver, it stays on your record for 55 years.

The table below shows the average increase for drivers with various incidents on their record:

At-Fault Accident$1,011$1,497$48648%
Bad Credit$1,011$2,049$1,037103%

Minimum car insurance requirements in Idaho

Most states require drivers to carry a minimum amount of liability car insurance, and Idaho is no exception. Drivers are required to carry 25/50/15 in liability coverage, which translates into:

  • $25k for injury/death per person.
  • $50k for injury/death per accident
  • $15k for damage to property

But state-required minimums are rarely enough coverage in a serious accident. If you cause an accident and the damages exceed your coverage levels, you will need to cover the damages out of pocket.

The most common required coverages are $25,000 bodily injury liability per person/ $50,000 bodily injury liability per accident and $25,000 property damage.

Experts typically recommend carrying 100/300/100 as a minimum liability coverage level.
