It is important to understand Idaho laws regarding mandatory auto insurance before deciding which policy is best for you as well as how much insurance you need. There are more than 110 auto insurance companies licensed to operate in Idaho, so one of them should be exactly what you want. These car insurance requirements apply to all drivers:

  • Regardless of registration status, all motorized vehicles accessing Idaho roadways must carry liability insurance for $25,000 (injury or death for one person), $50,000 (injury or death for more than one person), and property damage in the amount of $15,000. In lieu of insurance, an indemnity bond offered by a surety company can be purchased or, if certain guidelines are met, self-insurance is acceptable.
  • Operators must carry evidence of financial responsibility (proof of insurance or an acceptable alternative) in vehicles at all times.
  • Proof of financial responsibility is required as part of the registration process.
  • Underinsured motorist (UIM) and uninsured motorist (UM) coverage must be rejected, in writing, unless the insured chooses to include UIM and UM coverage as part of a policy.
  • Individual drivers can be specifically excluded.

There are important questions you should ask each insurance company you consider, so you can compare these car insurance companies against the same criteria. Keep in mind that Idahoans pay very low car insurance rates. An excellent way to do your comparison shopping is by requesting a quote using identical circumstances. These are some of the criteria to use when evaluating the companies.

  • Cost of car rental insurance
  • UM/UIM coverage required to be equal
