If you begin to pass a car and it suddenly speeds up to the posted speed limit, what should you do?

Answer: B — Drop back and wait

When you are in the process of passing a car and that vehicle unexpectedly accelerates to the posted speed limit, it is crucial to prioritize safety. Dropping back and waiting is the most responsible course of action in this scenario. This approach allows you to avoid a potentially dangerous situation, as trying to maintain your position beside the car while it speeds up could lead to collision risks. Maintaining a safe distance is essential as the other vehicle may not be aware of your intent to pass, and their increased speed can limit your maneuvering options. By dropping back, you give yourself the space to reassess the situation and determine when it is safe to continue with your maneuver or abandon it altogether. This choice also upholds defensive driving principles, which are critical for safe motorcycling.
