When you need to slow down unexpectedly, what should you do?

Flashing your brake light is a crucial safety measure when you need to slow down unexpectedly on a motorcycle. This action alerts drivers behind you that you are reducing your speed, providing them with the critical information they need to react appropriately. By signaling your intent to slow down, you help to prevent potential collisions and maintain safe traffic flow.

Using your horn, on the other hand, is typically reserved for warning others of your presence or alerting them to potential hazards rather than specifically indicating a change in your speed. Skidding your tires can lead to loss of control, which is particularly dangerous in emergency situations where slowing down is necessary. Signaling left or right primarily indicates a turn or a lane change, not a reduction in speed; hence, it does not serve the purpose of warning drivers to reduce their speed. Therefore, flashing your brake light is the most effective and safest method to communicate your need to slow down suddenly.
