This case involves a cyclist who was riding on a municipal bike and pedestrian trail in Utah. The cyclist came upon a group of 15 senior citizens who were leisurely walking on the trail coming from the opposite direction. The group of senior citizens was allegedly taking up a significant portion of the trail. The cyclist was traveling at a high speed and was unable to pivot out of the way or break before colliding with one of the senior citizens. The collision caused the senior citizen to fall and suffer a broken hip and the cyclist to suffer a broken arm. An accident reconstructionist with experience reconstructing bicycle accidents was sought to review the claims of both parties.
