When is it especially important to flash the brake light?

Flashing the brake light is particularly important when slowing down unexpectedly or in unexpected situations because it alerts other drivers to your actions and intentions. This is crucial for safety on the road, as it helps to prevent rear-end collisions by giving following drivers a clear visual cue that you are decreasing your speed. In circumstances where a sudden stop or slow down occurs, such as encountering a hazard or needing to yield, signaling with your brake light provides critical advance notice to those behind you. This becomes even more vital when visibility might be compromised or when vehicles are following closely, ensuring that all road users can react appropriately.
