Montana Draft Bill LC 863 Proposes Major Revisions to DUI Laws

Overview

Montana legislators have submitted a new draft request, designated LC 863, targeting comprehensive changes to the state impaired driving statutes. The measure carries the broad working title "Generally revise DUI laws." Drafting staff recently placed the measure on hold, pausing formal text development while lawmakers assess its policy goals.

Key Provisions

• Draft request status: The measure sits as an active drafting request rather than a fully numbered bill, giving sponsors time to alter provisions before committee introduction.

• Statutory focus: The bill targets Title 61, Chapter 8 of the Montana Code Annotated, which governs state impaired driving offenses, ignition interlock rules, and administrative sanctions.

• Procedural updates: Broad title placeholders like LC 863 typically address sentencing structures, treatment mandates, or evidentiary rules for chemical testing.

Impact on Drivers

Any shift in Montana DUI statutes directly alters court proceedings for accused motorists. Montana already enforces strict standards, including the 24/7 Sobriety Program for repeat offenders. A broad revision could adjust testing refusal consequences, change mandatory minimum jail terms, or modify driver license suspension periods. Drivers facing alcohol- or drug-related charges could see different plea options, altered diversion eligibility, or adjusted lookback windows for prior convictions.

Current Law vs Proposed Changes

• Current: Montana law sets a 0.08 blood alcohol concentration threshold, mandates substance use assessments, and imposes tiered penalties based on prior offenses within a ten-year lookback window.

• Proposed: LC 863 reserves legislative space to modify existing thresholds, penalty tiers, or enforcement procedures, though explicit statutory text remains paused pending sponsor direction.

What This Means For You

Existing Montana traffic codes remain in full effect today. A draft on hold creates no immediate legal liability, but it signals ongoing legislative interest in tightening DUI oversight across the state.

Pay attention to legislative committee schedules if you have an active charge or prior convictions on record. Statutory changes enacted during a legislative session can redefine probation conditions, ignition interlock requirements, and expungement rules. Drivers should track LC 863 as sponsors decide whether to release the hold and introduce formal bill text.
