Most states — except New Hampshire and Virginia — require drivers to carry at least the minimum liability car insurance to drive legally. Liability insurance in Idaho covers others’ injuries, property damage and legal expenses for accident-related lawsuits if you are at fault in an accident – up to your policy limits.

The average cost of liability insurance in Idaho is $438 a year — that’s $199 less than the national average of $637 .

Liability insurance does not cover damage to your vehicle or your or your passengers’ injuries. That’s why many Idaho drivers purchase additional coverage, such as collision and comprehensive insurance, to protect their own vehicles.

How much does liability insurance coverage cost in Idaho?

Liability insurance costs an average of $36 per month in Idaho for the coverage limit of 50/100/50, where $50,000 is for bodily injury per person, $100,000 is for bodily injury per accident and $50,000 is for property damage.

Liability insurance rates may vary based on your age, driving history, ZIP code, insurance company and if you purchase higher limits for added protection.

“As with any insurance policy, you need to assess the level of coverage you’re comfortable with relative to a cost you can afford,” says Rick Kautzer, director of product management at Dairyland Insurance.

How much auto liability insurance do I need in Idaho?

In Idaho, you are required to purchase state-mandated car insurance with liability limits of at least 50/100/50. These limits are the minimum legal requirement, but many experts recommend purchasing higher liability limits to protect your assets and provide greater financial security in case of an accident.

If you have significant assets or want more protection, you should consider buying liability auto insurance limits of 100/300/100. Most drivers also should purchase collision and comprehensive coverage.

“Minimum coverage limits are just that — the absolute minimum you’re required to carry, but perhaps insufficient to adequately protect you in the event of an accident,” Kautzer says.

Liability car insurance rates in Idaho for make and model

If you are a car enthusiast and drive an expensive BMW or an electric vehicle, you’ll pay higher car insurance rates in Idaho than someone driving a Honda or Chevrolet.

Liability car insurance rates for a Ford F-150 are $592 a year or $49 per month, whereas drivers with a Chevrolet Silverado 1500 pay $592 a year or $51 per month for the same coverage.

Purchasing only liability car insurance can make sense if you have an older car or don’t use your vehicle regularly. But if your car is newer or if you can’t afford to replace it, get full coverage car insurance with limits of 100/300/100 and collision and comprehensive coverage to protect your ride from unforeseen incidents.

Is liability car insurance coverage enough in Idaho?

While liability coverage is required by law in most states, it only covers the property damage and bodily injuries of others up to the limits of your policy. Liability coverage does not protect your car or your body if you are injured. If you’re at fault in an accident and have only liability coverage, you’ll be responsible for your own medical bills and vehicle repairs – and those for others beyond the limits of your policy.

That’s why you might want to carry various other types of coverage, Kautzer says.

“They can provide protection for injury to yourself, damage to your own car, and other expenses you might incur as a result of an auto accident,” he says.

Idaho drivers can protect their vehicles by getting additional types of auto insurance coverage, such as collision coverage, comprehensive coverage, personal injury protection (PIP) and uninsured/underinsured motorist coverage – in addition to increasing their liability limits.

Final thoughts on liability car insurance in Idaho

Buying the minimum amount of liability car insurance that your state requires — and nothing more — is usually the most affordable option in Idaho, but it may not be the best option for most drivers.

Carrying the minimum amount of liability coverage provides some financial protection when you are behind the wheel, but CarInsurance.com’s editors recommend that Idaho drivers opt for higher coverage levels for financial protection.

This can mean both higher levels of liability coverage with limits of 100/300/100 and other types of insurance, such as collision coverage, comprehensive coverage, personal injury protection (PIP) and uninsured/ underinsured motorist coverage.
