Which motorist action is a leading cause of car-bicycle crashes on the road?

The action of motorists turning right across the path of bicycle traffic is a significant factor in car-bicycle crashes. This occurs because many cyclists ride in bike lanes that may be adjacent to vehicle lanes, particularly at intersections or when roads are narrowing. When a motorist makes a right turn without properly checking for approaching bicycles, they may inadvertently cut off a cyclist who has the right of way. This lack of awareness and the sudden movement of the car can lead to a serious collision. Engaging in vigilant observation at intersections and signaling intentions can help reduce such risks. Understanding this dangerous behavior is crucial for both motorists and cyclists to promote safer road-sharing practices.
