Visual Distress Signals (VDSs) allow vessel operators to signal for help in the event of an emergency.
VDSs are classified as day signals (visible in bright sunlight), night signals (visible at night), or both day and night signals. VDSs are either pyrotechnic (smoke and flames) or non-pyrotechnic (non-combustible).
