Visual Distress Signals (VDSs)


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).

Vessels on federally controlled waters, such as the Great Lakes, must be equipped with visual distress signals that are U.S. Coast Guard–approved, in serviceable condition, and readily accessible.

  • All vessels, regardless of length or type, are required to carry night signals when operating between sunset and sunrise.
  • Most vessels must carry day signals also; exceptions to the requirement for day signals are:
    • Recreational vessels less than 16 feet in length
    • Non-motorized open sailboats that are less than 26 feet in length
    • Manually propelled vessels

If pyrotechnic VDSs are used, a minimum of three must be carried in the vessel.

An example of VDSs that could be carried on board to satisfy U.S. Coast Guard requirements is one handheld orange smoke signal (day), two floating orange smoke signals (day), and one electric light (night only).

It is prohibited to display visual distress signals while on the water unless assistance is required to prevent immediate or potential danger to persons on board.
