3.1 Montana Auto Insurance Requirements

Montana requires all registered vehicles to maintain liability insurance coverage. Understanding the state's minimum requirements, tort system, and coverage options is essential for Montana P&C producers.

Minimum Liability Coverage: 25/50/20

Montana's minimum auto liability requirements are often expressed as 25/50/20:

Understanding Split Limits

The 25/50/20 format means:

• First number (25): $25,000 maximum for any one person's bodily injuries
• Second number (50): $50,000 maximum total for all bodily injuries per accident
• Third number (20): $20,000 maximum for property damage per accident

Exam Tip: Montana's minimums are 25/50/20. Memorize this - it will be on the exam. Compare to neighboring states: Wyoming (25/50/20), Idaho (25/50/15), North Dakota (25/50/25).

Example Scenario

Accident with 3 injured people and $15,000 property damage:

Analysis: The policy pays $50,000 for bodily injury (the per-accident maximum) and $15,000 for property damage. The at-fault driver is personally responsible for the remaining $10,000.

Montana Tort System

Montana follows a tort (fault-based) system for auto accidents:

How the Tort System Works

Montana Comparative Negligence

Montana uses a modified comparative fault system:

• Injured party can recover if they are less than 51% at fault
• Recovery is reduced by percentage of fault
• If 51% or more at fault, recovery is barred entirely

Example: If you are 30% at fault for an accident and your damages are $10,000, you can recover $7,000 (70% of damages).

Uninsured and Underinsured Motorist Coverage

UM/UIM Requirements

Montana law requires insurers to offer UM and UIM coverage:

UM Coverage Triggers

UM coverage applies when:

• At-fault driver has no liability insurance
• Hit-and-run driver (phantom vehicle)
• At-fault driver's insurer is insolvent
• At-fault vehicle is stolen

UIM Coverage Triggers

UIM coverage applies when:

• At-fault driver has insurance but limits are insufficient
• At-fault driver's coverage exhausted
• Damages exceed at-fault driver's limits

Exam Tip: Montana requires insurers to OFFER UM/UIM coverage, but policyholders can reject it in writing. If no written rejection, coverage applies at liability limits.

Medical Payments Coverage

Montana does not require Personal Injury Protection (PIP), but medical payments coverage is available:

• Pays medical expenses regardless of fault
• Covers driver and passengers
• Typically $1,000 - $100,000 limits
• No deductible usually applies

Collision and Comprehensive

Collision covers:

• Collision with another vehicle
• Collision with objects (trees, poles, buildings)
• Overturn or rollover
• Subject to deductible

Comprehensive covers:

• Theft
• Vandalism
• Fire
• Weather damage (hail, flood)
• Animal collisions (deer strikes common in Montana)
• Subject to deductible

Exam Tip: Montana has high rates of deer-vehicle collisions. Comprehensive coverage covers animal strikes, while collision typically covers hitting a stationary object.
