Helena riders often share the road with drivers who are navigating heavier commuting traffic, turning into neighborhood entrances, or traveling through roadway work zones. Common crash patterns include:
- Left-turn and yield violations at intersections: Drivers misjudge a cyclist’s speed or fail to see a bike in the lane.
- Dooring and lane squeeze near busy corridors: When a vehicle stops or a door opens unexpectedly, cyclists can have little time to react.
- Construction-zone hazards: Uneven pavement, debris, narrowed lanes, and altered signage can contribute to loss of control.
- High-speed “last-second” maneuvers: Tailgating or abrupt swerves can force a rider into the travel lane or curb line.
These cases don’t hinge on “who was biking.” They hinge on whether the driver or another responsible party acted reasonably under the circumstances.
