For the Idaho Personal Lines exam, the Personal Auto Policy (PAP) is tested two ways: the national policy structure and the Idaho auto laws layered on top of it. This standalone guide walks through the lettered parts every PAP uses, then focuses on the Idaho rules an agent must apply every day—financial-responsibility minimums, the at-fault legal system, the required offer of uninsured/underinsured motorist coverage, and how policies can be cancelled or nonrenewed. Spend your study time on the Idaho overlay; that is where the state questions live.

The national fundamentals (quick version)

The Personal Auto Policy insures individuals and families for the vehicles they own and drive. It is divided into clearly labeled parts:

• Part A — Liability Coverage: pays for bodily injury (BI) and property damage (PD) the insured is legally responsible for, and includes a duty to defend with defense costs paid on top of the limit.
• Part B — Medical Payments: pays medical and funeral expenses for the insured and passengers regardless of fault.
• Part C — Uninsured/Underinsured Motorists (UM/UIM): pays your injuries when the at-fault driver has no insurance or too little.
• Part D — Coverage for Damage to Your Auto: Collision and Other Than Collision (Comprehensive), each with a deductible, paid at Actual Cash Value (ACV).
• Part E — Duties After an Accident or Loss and Part F — General Provisions set the rules.

The declarations page summarizes the named insured, covered vehicles, coverages, limits, and premium. An insured generally includes the named insured, the resident spouse, resident family members, and anyone using the covered auto with permission. Coverage territory generally includes the United States, its territories and possessions, and Canada. Eligible vehicles are private passenger autos, pickups, and vans not used primarily for business. That skeleton is the same nationwide; Idaho changes the dollar limits and the legal environment around it.

Idaho is an at-fault (tort) state

Idaho follows a tort (at-fault) system rather than a no-fault system. Whoever causes the crash is financially responsible, and the injured person recovers from that driver's liability insurance—or sues. Because of this, liability coverage and proof of financial responsibility are the backbone of Idaho auto regulation.

When both drivers share blame, Idaho uses modified comparative negligence. Picture a cutoff: an injured person whose fault is as great as the other party's—commonly described as the 50% bar—generally recovers nothing (verify the exact threshold). Below that line they can still collect, but the payout is trimmed by their own percentage of fault. This differs from a pure comparative system (where any at-fault claimant recovers something) and from a no-fault system (where each driver turns first to their own coverage).

Financial responsibility: the 25/50/15 minimums

Idaho's financial responsibility law requires owners of registered vehicles to maintain at least the minimum liability insurance, commonly stated as split limits of 25/50/15 (verify the current statutory figures):

• $25,000 bodily injury per person
• $50,000 bodily injury per accident
• $15,000 property damage per accident

Agents say this aloud as "25/50/15." These are bare-minimum floors—most clients should buy more to protect their assets. Besides insurance, Idaho may allow a motorist to show responsibility by posting an approved bond or deposit (verify). Driving uninsured is generally a misdemeanor subject to fines and possible license consequences, and certain violations may require filing an SR-22 certificate to prove future financial responsibility.

Required offer of uninsured/underinsured motorist coverage

Here is a point Idaho agents must get right: insurers writing auto liability must generally offer uninsured/underinsured motorist (UM/UIM) bodily injury coverage, and the insured may reject it only in writing.

• Uninsured Motorist (UM) protects you and your passengers when the at-fault driver carries no liability insurance (and typically when the driver flees the scene).
• Underinsured Motorist (UIM) applies when the at-fault driver has insurance, just not enough; it pays the difference between the other driver's lower BI limit and your UIM limit.
• The other driver must be legally at fault for the coverage to respond.

Unlike a coverage a customer must affirmatively request, Idaho's framework puts UM/UIM in front of the insured by default: a verbal "no thanks" is not enough—the rejection must be in writing.

No PIP, plus the optional coverages

• Idaho does not require PIP / no-fault coverage. Medical Payments (Med Pay) is available as an optional first-party coverage that pays medical and funeral costs regardless of fault.
• Collision pays for damage to your auto from impact with another vehicle or object; Comprehensive (Other Than Collision) pays for losses such as fire, theft, hail, vandalism, and hitting an animal. Both are optional, though a lender usually requires them, and a total loss is settled at actual cash value less any deductible.
• Common add-ons include towing and labor and rental reimbursement while the covered auto is being repaired.

Cancellation and nonrenewal notice

Idaho limits how and when an insurer can end a personal auto policy, and the notice generally must include the reason for the action. The timelines are commonly cited as follows (verify current figures):

• Cancellation for nonpayment of premium uses a shorter notice (often around 10 days).
• Other mid-term cancellations require a longer advance written notice (commonly around 30 days), and after a policy has been in force a set time the insurer may cancel only for limited reasons—chiefly nonpayment, driver's-license suspension/revocation, or fraud/material misrepresentation.
• Nonrenewal (declining to continue at the end of the term) likewise requires advance written notice so the insured can shop for replacement coverage.

Keep the short nonpayment window separate from the longer ordinary-cancellation / nonrenewal window.

Required vs. optional coverages in Idaho

Key Idaho numbers to memorize

Common exam traps

• Idaho is at-fault, not no-fault—there is no mandatory PIP here.
• 25/50/15—don't transpose the $15k property-damage figure into a bodily-injury slot.
• UM/UIM must be offered and rejected only in writing; a verbal rejection does not count.
• Modified comparative negligence: at the ~50% bar there is no recovery (verify the exact wording).
• UIM fills the gap (your UIM limit minus the other driver's BI payment); it isn't a second full benefit on top.
• Hitting an animal is Comprehensive, not Collision.
• Liability defense costs are paid in addition to the limit (national rule that still applies in Idaho).

Quick recap

• The PAP keeps its national Parts A–F structure; Idaho changes the limits and legal context.
• Idaho is a tort/at-fault state using modified comparative negligence, where a claimant at roughly the 50% fault bar recovers nothing (verify).
• Financial-responsibility minimums are 25/50/15 (verify), and owners of registered vehicles must maintain them.
• Uninsured/Underinsured Motorist BI must be offered and can be rejected only in writing.
• Idaho has no mandatory no-fault/PIP; Med Pay, Collision, and Comprehensive are optional.
• Cancellation for nonpayment uses a short (~10-day) notice; ordinary cancellation/nonrenewal uses a longer (~30-day) notice, and the notice states the reason.
