Montana Auto Insurance & Crash Law Library
A public legal education library for Montana automobile insurance and motor-vehicle crash law. Begin with the Montana issue, trace it to current Montana primary authority, and use the 23-guide library to investigate insurance coverage, insurer duties, liability, evidence, damages, reimbursement and settlement.
Start with Montana law
Automobile insurance law is state specific. Montana combines compulsory liability insurance, statutorily required uninsured-motorist coverage unless rejected, optional underinsured-motorist coverage, modified comparative negligence, important statutory insurer-conduct remedies, and a developed body of stacking and made-whole law.
Montana’s 23 published guides were completed under the first-generation Western States sequence. They remain the authoritative Montana navigation system, and their existing URLs are preserved.
California and Colorado later established the canonical production sequence used for new state libraries. The legal questions remain comparable across states, but several guide numbers differ.
Montana current-law snapshot
These starting points define major features of the Montana system. The complete statute, policy language, facts and controlling Montana authority remain necessary for legal analysis.
Montana’s ordinary minimum motor-vehicle liability limits under MCA §§ 61-6-103 and 61-6-301.
MCA § 27-1-702 permits recovery when claimant negligence is not greater than the negligence against which recovery is sought.
MCA § 33-23-201 requires UM protection unless rejected by the named insured.
Montana’s UM statute does not itself mandate UIM coverage. The policy and controlling cases therefore matter independently.
MCA §§ 33-18-201 and 33-18-242 create unusually important statutory standards and remedies.

What is distinctive about Montana?
Several Montana doctrines materially affect automobile-insurance investigation, claim handling and net recovery.
Direct statutory UTPA remedy
MCA § 33-18-242 permits insureds and qualifying third-party claimants to bring an independent action for specified violations of MCA § 33-18-201. Montana therefore has a particularly important statutory insurer-conduct system.
UM required; UIM optional
Montana requires uninsured-motorist coverage unless rejected by the named insured. Underinsured-motorist coverage is not mandated by the same statute and depends more heavily on the policy and Montana cases.
Developed made-whole doctrine
Montana has substantial made-whole and subrogation authority. The analysis requires attention to the covered loss, the actual recovery, costs of obtaining that recovery and the particular category of damage involved.
Formal time-limited demand statute
MCA § 33-18-251 establishes detailed requirements for qualifying time-limited settlement demands, including a statutory response period. The current text should be followed precisely.
Montana’s UTPA structure deserves special attention
Montana has one of the more consequential statutory insurer-conduct systems in the Western States library.

Compare Montana with the other Western states
Montana is one part of the 16-state Western States Law Library. Comparative research is useful, but the controlling comparison is the legal issue—not an assumption that identical guide numbers mean identical subjects.
Follow Montana Guides 01–23
Within Montana, use the numbers published on this state landing page. They remain the authoritative navigation sequence for Montana’s existing guide URLs.
Match the topic first
Use the crosswalk when comparing Montana with California, Colorado or a newly built state. Do not assume identical guide numbers identify identical subjects.
Montana is particularly useful for comparative research involving direct third-party insurer remedies, statutory UTPA liability, stacking doctrine, made-whole principles and formal time-limited settlement demands.

Start with the complete Montana insurance and liability map.
A Montana crash claim requires more than identifying one insurance policy. Determine who qualifies as an insured. Identify every liability and first-party policy. Separate mandatory UM from optional UIM. Test stacking where multiple premiums, vehicles or policies exist. Evaluate Montana UTPA duties. Allocate comparative negligence. Preserve crash evidence. Document the complete damages. Identify subrogation and reimbursement interests. Then evaluate settlement and release only after the complete legal and insurance structure is visible.
