The leading cause of vehicle crashes across the nation is driving under the influence of drugs and alcohol. Distracted driving and speeding are also common causes of car accidents. When it comes to bicyclists and motor vehicle crashes, drivers of motor vehicles are not often aware of cyclist rights, and may not know how to interact with a cyclist when they see them on the road. The leading cause of bicycle accidents is collisions with other motorists. Additionally, most bicycle accidents happen on long stretches of road as opposed to intersections. Speeding and reduced visibility of bicyclists typically contribute to bicycle accidents in these circumstances. Cyclists can help minimize the danger on roadways by riding with the traffic flow, wearing bright and reflective clothing, and using clear, easy-to-understand hand signals.
