When approaching a controlled intersection with a waiting vehicle, what should a motorcycle rider do?

Answer: B — Reduce speed and be ready to react

When approaching a controlled intersection with a waiting vehicle, reducing speed and being ready to react is essential for safety. This approach allows the motorcycle rider to assess the situation effectively, including the behavior of the waiting vehicle and any changes in traffic signals. By reducing speed, the rider can maintain control of the motorcycle and prepare for any sudden movements from the waiting vehicle, such as a left turn or unexpected entry into the intersection. This proactive strategy minimizes the risk of accidents and ensures that the rider is prepared for any unexpected scenarios. Being alert and ready to react is crucial in maintaining safe riding practices, especially in urban environments where intersections can present numerous hazards.
