If you plan to stop unexpectedly, how should you warn other drivers?

Flashing your brake light is an effective way to warn other drivers that you are planning to stop unexpectedly. By doing so, you visually communicate your intention to reduce speed or stop, which helps to alert vehicles behind you to prepare for a possible sudden stop. The brake lights on a motorcycle are typically located on the rear, making them a prominent signal for following drivers.

While honking your horn can also serve as a warning, it's not as universally recognized as a signal for stopping as flashing the brake lights. Hand signals are useful for indicating turns or lane changes, but they might not be as effective in gaining the attention of drivers in potential stop scenarios. Turning on hazard lights is primarily meant to indicate that your vehicle is stopped or experiencing difficulties, but it may not serve as a proactive warning while you are still in motion.

Overall, flashing your brake light is the most direct and recognized method for communicating your intention to stop, making it the best choice in this situation.
