What should riders do when approaching a blind intersection with a stop sign?

Answer: B — Stop at the stop sign before moving forward

The action of stopping at the stop sign before moving forward is crucial for safety when approaching a blind intersection. This practice allows the rider to come to a complete stop, which is essential for assessing the situation at the intersection. Failing to stop could result in a collision with a vehicle that may not be immediately visible. Stopping enables the rider to look in both directions, ensuring that it is safe to proceed and that there are no oncoming vehicles, pedestrians, or cyclists that could pose a danger. It's important to adhere to traffic regulations, as they are designed to protect everyone on the road. Thus, coming to a complete stop at the stop sign is a fundamental practice that enhances safety for motorcyclists in potentially hazardous traffic situations.
