A driver fails to yield the right of way by not letting another vehicle, pedestrian, bicycle, or lawful road user go first when traffic rules require it.

That usually happens at intersections, when turning left across traffic, entering from a side street or driveway, merging, or approaching a crosswalk. The mistake may look small - a rushed turn, rolling through a stop, or assuming another driver will slow down - but it can put two people into the same space at the same time. In Montana, right-of-way duties are set out across Montana Code Annotated Title 61, Chapter 8 (2023), and a violation can lead to a traffic citation and become strong evidence of unsafe driving.

Practically, this matters because failure to yield is a common cause of side-impact crashes, pedestrian injuries, and motorcycle wrecks. Those collisions often leave people with neck, back, chest, and head injuries even at moderate speeds. Near large commuting areas or shift changes, including around Malmstrom Air Force Base, a brief misjudgment at an intersection can have serious consequences.

In an injury claim, a failure-to-yield ticket can support an argument that the other driver was negligent, but it does not always decide the case by itself. Insurers and courts still look at speed, visibility, signals, and whether anyone else shares fault under Montana's comparative negligence rules. That can affect liability, settlement value, and whether damages are reduced.
