When should a driver use their hazard lights?

Hazard lights serve an important function in alerting other drivers to a potential hazard or unusual situation regarding your vehicle. The correct situation to use hazard lights is specifically when the vehicle is disabled or when you are temporarily stopped on the roadway. This is crucial because it notifies other drivers that they should exercise caution, as your vehicle may be stationary in a place where it could pose a risk if drivers are unaware.

Using hazard lights in these circumstances enhances safety for both the stopped vehicle and oncoming traffic, making it clear that the driver is not able to move forward as expected. This can be especially vital on busy roadways or during conditions that decrease visibility, ensuring that other motorists can adjust their driving behavior to avoid a collision.

While hazard lights may seem useful during heavy rain or when parked on the side of the road, they are primarily intended for situations of disablement or immediate danger rather than as a general signal for weather conditions or parking. Additionally, using them while changing lanes could create confusion, as it may mislead other drivers about your intentions.
