It's the Law

Visual Distress Signals (VDSs)

Vessels on federally controlled waters must be equipped with visual distress signals (VDSs) that are USCG–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 that are less than 16 feet in length
  • Non-motorized open sailboats that are less than 26 feet in length
  • Manually propelled vessels

Note: Although Lakes Champlain and Memphremagog are under federal control, VDSs are not required on these waters.

If pyrotechnic VDSs are used, they must be dated. Expired VDSs may be carried on board, but a minimum of three unexpired VDSs must be carried in the vessel.

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).
