To meet the requirement for the number of VDSs on board, what must be true about pyrotechnic VDSs?
To satisfy the legal carriage requirements for Visual Distress Signals (VDS), pyrotechnic VDSs must be unexpired (within their service life date) and Coast Guard-approved. Specifically, for vessels required to carry them, you must have a minimum of three signals for day use and three for night use, or three combination day/night signals.
Key Takeaways
- Service Life: Pyrotechnic signals are usually valid for 42 months from the date of manufacture.
- Approval: They must clearly bear a U.S. Coast Guard approval number.
- Quantity: A minimum of three signals is required to meet the count requirement.

Condition 1: Service Life and Expiration
The most critical factor regarding pyrotechnic VDSs is their expiration date. Because the chemicals in flares and smoke signals deteriorate over time, the U.S. Coast Guard (USCG) mandates that they are replaced regularly.
- Validity Period: Most pyrotechnics have a service life of 3.5 years (42 months).
- Inspection: You must check the date printed on the device. If the “Use By” date has passed, the device no longer counts toward your legal carriage requirement.
- Storage: While expired flares cannot be used to meet the legal requirement, many safety experts suggest keeping them on board as “backups” (provided they aren’t damaged), as long as you also have the required number of fresh, unexpired signals.
Pro Tip: Always store pyrotechnic VDSs in a red or orange watertight container marked “Distress Signals” in a dry, readily accessible location.
Condition 2: Coast Guard Approval
To meet the requirement, the signals must be specifically tested and approved for maritime use.
- Markings: Each device must have a legible USCG approval number.
- Condition: The device must be in “serviceable condition.” This means no signs of corrosion, cracks in the casing, or moisture damage. If a flare’s label is unreadable, it is technically non-compliant during a vessel inspection.
Condition 3: Quantity and Combination
The law doesn’t just care about what they are, but how many you have and when they can be used.
- The Rule of Three: You must carry a minimum of three signals for daytime use and three signals for nighttime use.
- Day/Night Selection:
- You can carry three combination signals (like handheld red flares or aerial flares) which count for both day and night.
- You can carry three day-only signals (like orange smoke) AND three night-only signals (like certain electric lights, though those are non-pyrotechnic).
- Launchers: If you use aerial pyrotechnic signals that require a launcher (like a flare gun), the launcher itself must also be USCG-approved.

Frequently Asked Questions
1. Can I use an expired flare in an emergency?
Yes. In a true life-threatening distress situation, you may use any means available to signal for help. However, expired flares are less reliable and may fail to ignite, which is why they don’t count toward your legal requirements.
2. What happens if I have 2 unexpired flares and 1 expired flare?
You are out of compliance. You must have at least three unexpired signals that meet the day/night requirements to avoid a citation during a Coast Guard or Law Enforcement inspection.
3. Are there non-pyrotechnic alternatives?
Yes. You can meet the night requirement with an electric distress light (SOS) and the day requirement with a distress flag. These do not expire, but they must still be USCG-approved.
