What is a common cause of motorcycle accidents?

Excessive speed and improper lane positioning are both significant factors that contribute to motorcycle accidents. Excessive speed reduces a rider's ability to react to sudden obstacles or changes in road conditions, making it harder to maintain control of the motorcycle. Riders traveling at high speeds may also face increased stopping distances and a greater risk of severe injuries in the event of an accident.

Improper lane positioning, such as riding too close to the edge of the lane or weaving between traffic, can also lead to dangerous situations. This can limit a rider’s visibility and create blind spots, increasing the likelihood of collisions with other vehicles. Proper lane positioning allows for better control and visibility, decreasing the chance of accidents.

By recognizing that both excessive speed and improper lane positioning can significantly elevate the risk of motorcycle accidents, it becomes clear why the choice indicating that both are common causes is the most accurate response.
