The cheapest car insurance may not provide sufficient protection, so how much insurance should you buy? Bare-bones coverage may be a good choice if you have few assets or have an old car and don’t drive much. But if you have a home and investments, consider buying more insurance. If you don’t, you’re at risk for having your money and house taken to cover the cost of an accident. If you financed your car you will be required to get additional comprehensive and collision coverage.

Use our How Much Car Insurance Do You Need? tool to get a recommendation.


We recommend you buy more insurance than is required to legally drive a car in your state, especially if you have savings and assets. The more money you have, the more likely you are to be sued following a car accident should your insurance be insufficient to cover all the expenses. If your net worth is:

  • less than $50,000, choose at least 50/100/50
  • between $50,000 and $100,000, choose at least 100/300/100
  • more than $100,000, choose at least 250/500/100

If you’re leasing or financing your car, you must get coverage of 100/300/100 or higher.

Collision and comprehensive

Collision coverage pays for damage to your car after an accident that you cause. Comprehensive insurance pays to replace stolen cars and for damages from vandalism, flooding, hail, fire and animal strikes. If your car is:

  • less than 10 years old, you should strongly consider buying collision and comprehensive.
  • more than 10 years old, only buy collision and comprehensive if your car is worth $3,000 or more, if you couldn’t afford to replace your car if it’s wrecked, or if you just want more protection on your policy.

For drivers in Idaho, collision costs an average of $430 yearly, comprehensive is $131, according to rate data. If you buy comp and collision, check our guide to choosing a deductible amount.

Medical coverage (MedPay)

Medical payments coverage can help pay for the medical or funeral expenses of covered drivers and passengers after an accident, regardless of fault, up to $25,000. In most states, including Texas, it’s an optional addition to your car insurance policy. MedPay does the following:

  • Covers you and your passengers’ medical expenses
  • Pays for expenses after health insurance limits are exceeded
  • Offers additional protection to insured drivers who are hit by a car while walking or biking

If you and your passengers:

  • Don’t have health insurance, or have a plan that doesn’t cover car accidents or has low limits, we recommend that you add medical coverage of at least $5,000 to your car insurance policy.
  • Do have health insurance, it’s still a good idea to have medical coverage if you want the best protection in your policy, as it can pay out after your health benefits are maxed out.

Gap insurance

If you don’t own your car outright and have an accident, gap insurance pays the difference between the cash value of your car and the current outstanding balance on your loan or lease.

  • If you’re financing your car, your car is less than one year old and you’ve put less than 20 percent down on it, you should buy gap insurance. If not, you don’t need gap insurance.
  • If you’re leasing your car, it’s a good idea to buy gap insurance if you aren’t already required to in your lease agreement.
  • If you own your car outright, you don’t need gap insurance.

Idaho Car Insurance Laws

RoadsNumber of Fatal Accidents

Idaho has very middle-of-the-road liability limits of $25,000 per person and $50,000 per accident for bodily injury and $15,000 for property damage. If you have a family or own a home, the industry standard for protection is 100/300/50.

Off-roading rules: Off-roading on ATVs, UTVs, motorbikes and other specialty off-roading vehicles is popular in Idaho. The requirements vary depending on where you are riding. Registration of your vehicle is almost always needed, but insurance may not be unless you are also driving on state or city roads with your vehicle.

Electronic proof of insurance is accepted: While it’s wise to still carry your paper insurance card in the vehicle or in your wallet, if you have proof of auto insurance on your smart phone or tablet, law enforcement and other state officials will accept it.

Violations, points and length on record: Idaho’s Transportation Department records moving violations that occur in Idaho, other states and Canada. Points stay on your record for three years after the conviction dates.

Discounts for ages 55+: Idaho auto insurance providers are required to offer older drivers (55+ years of age) a discount for completing an approved accident-prevention class. The discount is good for three years and is renewable.

Uninsured motorist penalties for Idaho: You may be fined $206, your license may be suspended and you may be required to file an SR-22 form. If you were driving without privileges (had your license suspended, revoked, etc. due to your previous citation), this offense is much more serious and carries a mandatory minimum of two days in jail, and up to six months. It also carries up to a $1000 fine, and it carries an additional license suspension of six months.

Electronic proof of insurance: Idaho is one of 31 states that allow drivers to show proof of insurance during a traffic stop on a smartphone.
