What is one way to indicate your intention to stop or slow down while riding?

Answer: B — Flash your brake light

Flashing your brake light is an effective way to indicate your intention to stop or slow down while riding. This action provides a clear visual cue to other drivers on the road, alerting them that you are decreasing your speed or preparing to stop. It is especially helpful in situations where other vehicles may be closely following you, as it enhances safety by ensuring that they have enough time to react to your change in speed. Using hand signals, although a valid method of communication on a motorcycle, is better suited for indicating a turn or lane change rather than simply slowing down or stopping. Gradually slowing down is important for controlling your speed but may not effectively communicate your intention to other drivers. Letting your engine idle does not provide any notification to surrounding vehicles and can actually be misleading as it suggests that you are maintaining a steady speed rather than intending to slow down or stop.
