How can you alert other drivers that you are slowing down in an unusual way?

Flashing your brake light is an effective way to alert other drivers that you are slowing down, particularly in situations where you may need to signal your decrease in speed quickly and clearly. This method draws attention to your motorcycle and communicates your intention more effectively than some other signals because it is a direct indicator that you are applying the brakes. This is especially important on a motorcycle, which can be less visible than larger vehicles.

In contrast, waving your hand may not be noticeable enough to other drivers, especially if there is a significant distance or traffic present. Flashing your headlight can be used to gain attention but is generally more suited for signaling your presence or intentions rather than specifically indicating you are slowing down. Using your turn signal is primarily intended for indicating a change in direction rather than a reduction in speed. Thus, while those options can have their place in roadway communication, flashing your brake light is the most direct and effective method to alert those around you that you are about to slow down.
