Yes, cyclist fatigue can establish comparative negligence if contributing to accidents. Extreme exhaustion might impair judgment, reaction time, and bike handling. However, driver duties to avoid striking cyclists remain regardless. Document ride length, conditions, and any signs of impairment. Fatigue alone rarely bars recovery unless clearly causing erratic behavior leading to accidents.
Distinguish normal exertion from dangerous exhaustion. Competitive cyclists and commuters routinely ride while tired without negligence. Focus remains on whether fatigue actually contributed to causing accidents versus mere presence. Driver negligence typically outweighs cyclist fatigue in fault allocation. Build evidence showing safe cycling despite fatigue or that exhaustion didn’t contribute to collision causation.
