Idaho Does Not Mandate Personal Injury Protection
Idaho does not require personal injury protection coverage. The state mandates only liability insurance: $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $15,000 for property damage. PIP is an optional coverage you can add to any vehicle on your policy, but it is not a condition of registration or legal driving in Idaho.
This matters for households insuring multiple vehicles because you are not paying for mandatory PIP on every car. If you add PIP, you choose which vehicles carry it and at what limit. Many drivers assume PIP is required because states like Oregon, Washington, and Utah mandate it, but Idaho's minimum-coverage framework stops at liability.

What Personal Injury Protection Actually Covers
Personal injury protection pays medical expenses, lost wages, and sometimes funeral costs for you and your passengers after an accident, regardless of who caused it. PIP is first-party coverage: it pays your own bills before you file a claim against the at-fault driver's liability policy.
In states that mandate PIP, the coverage kicks in immediately and reduces the need to pursue the other driver's insurer for medical costs. Idaho does not mandate it, so if you carry only the state minimum liability limits, your own medical bills after an accident fall to your health insurance, out-of-pocket savings, or a claim against the at-fault driver's bodily-injury liability coverage.
The coverage applies per vehicle on your policy, so if you insure three cars and add PIP to all three, each vehicle carries its own limit. If you add PIP to only one vehicle, only occupants of that vehicle are covered under the PIP policy.
Idaho does not require PIP, so every dollar you spend on it is optional. If your household carries strong health insurance, PIP may duplicate coverage you already have.
When Adding PIP Makes Sense for Multi-Vehicle Households
If your household health insurance carries high deductibles or excludes auto-accident injuries, PIP covers medical expenses immediately without waiting for fault determination. This matters most when multiple drivers share vehicles: a passenger injured in your car is covered under your PIP limit, even if they have no auto insurance of their own. Households with teen drivers, elderly passengers, or frequent carpooling often add PIP to the vehicles those groups use most.
If your household carries comprehensive health insurance with low out-of-pocket maximums, PIP may duplicate coverage. Compare your health plan's auto-accident treatment rules against PIP's per-person limit. Some health insurers subrogate against auto liability policies, meaning they will pursue the at-fault driver's insurer to recover costs they paid; PIP pays first and does not require subrogation. The trade-off is cost: adding PIP to three vehicles raises your total premium, and the benefit depends on how often you would use it versus your existing health coverage.

How PIP Interacts with Liability and Uninsured Motorist Coverage
PIP pays your own medical bills regardless of fault. Liability coverage pays the other driver's bills when you cause the accident. Uninsured motorist coverage pays your bills when an at-fault driver has no insurance. These three coverages do not overlap: each addresses a different scenario.
Idaho does not require uninsured motorist coverage either, but many carriers bundle UM with liability as a package. If you carry UM and PIP together, PIP pays first up to its limit, then UM covers additional medical costs if the at-fault driver is uninsured. If you carry PIP but no UM, and an uninsured driver hits you, PIP covers your immediate medical expenses up to its limit, and you pursue the at-fault driver directly for costs beyond that.
For households insuring multiple vehicles, this layering matters because you can structure different coverage combinations on different cars. A vehicle driven daily in high-traffic areas may carry PIP and UM; a vehicle driven occasionally on rural roads may carry liability only. The state does not require uniform coverage across every vehicle on your policy.
Idaho Uninsured Motorist Rate
6.4%
Approximately 6.4% of Idaho motorists drive without insurance. This rate is below the national average, but it means roughly one in sixteen drivers on Idaho roads carries no liability coverage to pay your medical bills if they cause an accident.

Comparing Carriers That Offer PIP in Idaho
Not every carrier writing auto insurance in Idaho offers personal injury protection as an optional add-on. Carriers confirmed to write PIP in Idaho include Allstate, American Family, Farmers, Geico, Liberty Mutual, Progressive, State Farm, and USAA. If you want PIP on your multi-vehicle policy, confirm the carrier you are comparing offers it before you finalize coverage.
PIP pricing varies by carrier, vehicle, and the limit you select. Request quotes with and without PIP on each vehicle to see the per-vehicle cost difference, then decide which cars in your household justify the additional premium.
Structure Your Idaho Multi-Vehicle Policy with the Right Optional Coverages
Idaho's liability-only mandate gives you control over every other coverage decision. PIP is optional, uninsured motorist is optional, and collision and comprehensive are optional unless your lender requires them. For households insuring multiple vehicles, this flexibility means you can tailor each car's coverage to how it is used, who drives it, and what financial exposure it represents. Compare carriers that write the optional coverages your household needs, request per-vehicle quotes that break out each coverage's cost, and structure a policy that fits your household's medical insurance, driving patterns, and budget.
