Idaho Auto Insurance Requirements

Idaho law requires all motor vehicle owners to maintain minimum liability insurance coverage. Understanding these requirements is essential for Idaho P&C insurance producers and is heavily tested on the state exam.

Minimum Liability Requirements: 25/50/15

Idaho's mandatory minimum liability limits are among the more modest in the nation:

Required Limits

How Split Limits Work

Example Scenario: A driver causes an accident injuring three people:

• Person A: $30,000 in injuries
• Person B: $20,000 in injuries
• Person C: $15,000 in injuries
• Total: $65,000

With 25/50/15 coverage:

• Person A receives: $25,000 (per-person limit)
• Person B receives: $20,000 (full amount, under per-person limit)
• Person C receives: $5,000 (remainder of $50,000 per-accident limit)
• Insured is personally liable for: $15,000 (excess over policy limits)

Exam Tip: Memorize Idaho's minimum limits: 25/50/15. This is one of the most frequently tested items on the Idaho P&C exam. The mnemonic "25-50-15" rolls off the tongue.

Idaho's Tort System

At-Fault Insurance System

Idaho uses a traditional tort (at-fault) system for auto accidents:

How It Works:

1. Determine who caused the accident (at-fault driver)
2. At-fault driver's insurance pays damages
3. Injured parties can sue if damages exceed policy limits
4. Comparative negligence reduces recovery proportionally

Comparative Negligence

Idaho follows a modified comparative negligence rule:

Example:

• You suffer $50,000 in damages
• You are found 30% at fault
• Your recovery: $50,000 - 30% = $35,000

Uninsured/Underinsured Motorist Coverage (UM/UIM)

Idaho UM/UIM Requirements

Idaho law requires insurers to offer UM/UIM coverage, but policyholders may decline:

UM Coverage

Uninsured Motorist (UM) coverage protects you when:

• At-fault driver has no insurance
• At-fault driver is a hit-and-run (physical contact typically required)
• At-fault driver's insurer is insolvent

UIM Coverage

Underinsured Motorist (UIM) coverage protects you when:

• At-fault driver has insurance
• Their limits are insufficient to cover your damages
• Pays the difference up to your UIM limit

Exam Tip: Idaho requires UM/UIM to be OFFERED but allows rejection IN WRITING. This is different from states where UM/UIM is mandatory with no rejection option.

Proof of Insurance Requirements

What Idaho Law Requires

All drivers must carry proof of insurance and present it:

• When requested by law enforcement
• At time of vehicle registration
• After an accident

Acceptable Proof

• Insurance ID card (paper or electronic)

Electronic Proof: Idaho accepts proof of insurance displayed on a smartphone or electronic device.
