In what situation should a driver use their hazard lights?

The proper use of hazard lights is intended to alert other drivers of a potential hazard or an emergency situation involving your vehicle. When a driver is parked on the side of the road or experiencing a breakdown, activating hazard lights serves as a warning signal to other road users, indicating that your vehicle is not in motion and that they should exercise caution when passing. This precaution is particularly important in situations where visibility is compromised or where your vehicle could create a hazard for oncoming traffic.

Using hazard lights in this context helps to enhance safety for both the driver in distress and other road users. It communicates that the vehicle is stationary due to an unexpected circumstance, which can help prevent accidents and ensure the safety of everyone involved.
