What does it indicate when a driver flashes their headlights at you?

Flashing headlights is commonly used as a communication tool between drivers. When a driver flashes their headlights at you, it typically serves as a warning about something that might be hazardous ahead, such as an accident, construction, or other obstructions on the road. This gesture helps alert other drivers to potential dangers that they might not be aware of, allowing them to take necessary precautions.

Understanding this can be particularly useful for ensuring safety on the roads. Recognizing this behavior can prompt drivers to be more vigilant and to assess their surroundings more carefully, contributing to a safer driving experience for everyone.
