What does it indicate when a driver has their hazard lights on?

Having hazard lights activated signals to other drivers that the vehicle may be stopped or in distress. This is an important safety feature designed to alert other road users about a potential hazard. When a driver turns on their hazard lights, it typically means that they are not in a position to drive safely or that their vehicle is stationary due to a breakdown, emergency, or other situation that necessitates caution from other motorists. Understanding this signal is crucial for maintaining road safety and allowing other drivers to navigate around a stationary or distressed vehicle effectively.

The other options could imply different situations, but they do not align with the primary purpose of hazard lights, which is to indicate a need for increased caution due to an unusual or emergency situation.
