A hazard board is merely advisory and are intended to keep racers aware of changes in circumstances (an example being a car that has pulled off into a reasonable position, the driver is out of the car, and that there are no marshals trackside). As a hazard board is being used you can pass it at full racing speed, overtake, etc, which of course differs from a yellow flag. Hazard boards are used fairly frequently - although how visible they are is a debatable point.
