25 multiple-choice questions for the boater safety (boating license) exam. Pick an answer to see the rule behind it, quoted from the official source.
1. Which of the following is a valid combination of visual distress signals that meets both day and night requirements according to the examples provided?
Answer: Two hand held red flares and one parachute red flare. The regulation lists the combination of two hand held red flares and one parachute red flare as a valid example for meeting both requirements.
33 CFR § 175.130(b): “Examples—the combination of two hand held red flares (160.021), and one parachute red flare (160.024 or 160.036) meets both day and night requirements.”
2. Under what condition does a State statute regarding children wearing Personal Flotation Devices (PFDs) take precedence over the general federal requirement in § 175.15(c)?
Answer: If the State statute establishes any requirement for children of a certain age to wear an appropriate Coast Guard-approved PFD. The regulation states that applicable State statutes regarding children's PFDs supersede the federal baseline requirement within that State's jurisdiction.
33 CFR § 175.25(b): “If the applicable State statute establishes any requirement for children of a certain age to wear an appropriate PFD approved by the Coast Guard, then that requirement applies on the waters subject to the State's jurisdiction instead of the requirement provided in § 175.15(c) of this part.”
3. When inspecting an inherently buoyant PFD, which condition of the buoyant material renders the device non-compliant?
Answer: The buoyant material has become hardened, non-resilient, permanently compressed, waterlogged, oil-soaked, or shows evidence of fungus or mildew. The rule lists specific deterioration signs for inherently buoyant materials, including hardening, compression, waterlogging, oil-soaking, or fungal growth, which compromise performance.
33 CFR § 175.23(b): “Buoyant material that has become hardened, non-resilient, permanently compressed, waterlogged, oil-soaked, or which shows evidence of fungus or mildew”
4. Under what specific condition is the inflation system of an inflatable PFD permitted to be unarmed?
Answer: When the PFD is worn inflated and otherwise meets the requirements. The rule allows the inflation mechanism to be unarmed only if the PFD is currently worn in an inflated state and meets other structural requirements.
33 CFR § 175.23(d): “The inflation system of an inflatable PFD need not be armed when the PFD is worn inflated and otherwise meets the requirements of paragraphs (a) and (c) of this section.”
5. When is a launcher required to be carried alongside a visual distress signal?
Answer: When the visual distress signal requires a launcher to activate. The rule mandates that if the specific distress signal chosen needs a launcher to function, that launcher must also be on board.
33 CFR § 175.113(a): “When a visual distress signal carried to meet the requirements of § 175.110 requires a launcher to activate, then a launcher approved under 46 CFR 160.028 must also be carried.”
6. If no earlier report is required by the specific injury or death clauses, within how many days must the casualty report be submitted?
Answer: Within 10 days. The regulation sets a default deadline of 10 days for reports when specific shorter deadlines for injuries or deaths do not apply.
33 CFR § 173.55(b): “Within 10 days of the occurrence or death if an earlier report is not required by this paragraph.”
7. If a recreational vessel built in model year 2016 has previously installed fire extinguishers with capacities lower than current standards, what is the operator required to do?
Answer: Maintain the existing extinguishers in good condition without replacement. Vessels built in or before model year 2016 are allowed to keep older extinguishers provided they are kept in good working order.
33 CFR § 175.380(a): “Previously installed extinguishers with extinguishing capacities that are less than what is required in table 1 to § 175.320(a)(1) or Table 4 to § 175.320(b)(1) need not be replaced but must be maintained in good condition.”
8. When is a sailing vessel required to exhibit a conical shape with the apex downward?
Answer: When proceeding under sail when also being propelled by machinery. The regulation specifies that the conical shape is required for vessels using both sail and machinery propulsion.
33 CFR § 83.25(e): “A vessel proceeding under sail when also being propelled by machinery shall exhibit forward, where it can best be seen, a conical shape, apex downward.”
9. If you refuse to submit to a chemical test when directed by a law enforcement officer who has reasonable cause, what is the consequence regarding your status?
Answer: You are presumed to be under the influence of alcohol or a dangerous drug. Refusing a directed chemical test results in a presumption that the operator is under the influence.
33 CFR § 95.040(a): “If an individual refuses to submit to or cooperate in the administration of a timely chemical test when directed by a law enforcement officer based on reasonable cause, evidence of the refusal is admissible in evidence in any administrative proceeding and the individual will be presumed to be under the influence of alcohol or a dangerous drug.”
10. When submitting a boating accident report, which specific identifier for the reporting operator's vessel must be included if available?
Answer: The manufacturer's hull identification number. The regulation requires the manufacturer's hull identification number for the reporting operator's vessel in the accident report.
33 CFR § 173.57(b): “(25) Manufacturer's hull identification number, if any, of the reporting operator's vessel;”
11. Which of the following is NOT listed as an authorized term for the type of vessel in the casualty report?
Answer: Jet ski. The rule lists 'personal watercraft' as the authorized term, whereas 'Jet ski' is a brand name or common term not included in the specific list of authorized terms provided.
12. You are operating a vessel aground in restricted visibility. In addition to the standard bell and gong signals, what specific bell pattern must you sound?
Answer: Three separate and distinct strokes on the bell immediately before and after the rapid ringing of the bell. Vessels aground must add three distinct bell strokes before and after the standard rapid ringing to distinguish their status from anchored vessels.
33 CFR § 83.35(h): “A vessel aground shall give the bell signal and if required the gong signal prescribed in paragraph (g) of this Rule and shall, in addition, give three separate and distinct strokes on the bell immediately before and after the rapid ringing of the bell.”
13. What is the minimum visibility range required for the light used to supplement whistle signals during maneuvering?
Answer: 2 miles. The regulation specifies that the supplementary light signal must be visible at a minimum range of 2 miles.
33 CFR § 83.34(b): “The light used for this signal shall, if fitted, be one all-round white or yellow light, visible at a minimum range of 2 miles, synchronized with the whistle, and shall comply with the provisions of Annex I to these Rules (33 CFR part 84).”
14. Under what specific condition is a person using a sailboat exempt from the requirement to carry visual distress signals?
Answer: If the sailboat is of completely open construction, not equipped with propulsion machinery, and under 26 feet in length. Small sailboats under 26 feet that are open and lack propulsion machinery are specifically exempted from carrying visual distress signals.
33 CFR § 175.115(c): “(c) A person using a sailboat of completely open construction, not equipped with propulsion machinery, under 26′ in length.”
15. Which type of vaporizing liquid is NOT acceptable for use in portable fire extinguishers on recreational vessels?

16. When displaying the required number on the forward half of a recreational vessel, what is the minimum height requirement for the characters?
Answer: 3 inches. The regulation mandates that the vessel number characters must be at least 3 inches tall to ensure visibility.
33 CFR § 173.27(a): “Be in plain vertical block characters of not less than 3 inches in height;”
17. Two power-driven vessels are meeting on reciprocal or nearly reciprocal courses, creating a risk of collision. How should each vessel alter its course?
Answer: Alter course to starboard so that each passes on the port side of the other. In a head-on meeting situation, both vessels must turn to starboard to pass port-to-port.
33 CFR § 83.14(a): “Unless otherwise agreed, when two power-driven vessels are meeting on reciprocal or nearly reciprocal courses so as to involve risk of collision each shall alter her course to starboard so that each shall pass on the port side of the other.”
18. Under what circumstances does the federal regulation on operating a vessel under the influence apply to a vessel owned in the United States?
Answer: When the vessel is operating on the high seas. The regulation extends its applicability to U.S.-owned vessels operating on the high seas, in addition to those on U.S. jurisdictional waters.
33 CFR § 95.005(a): “This part is applicable to a vessel (except those excluded by 46 U.S.C. 2109) operated on waters subject to the jurisdiction of the United States, and to a vessel owned in the United States on the high seas.”
19. A power-driven vessel less than 12 meters in length is underway at night. What lighting configuration is permitted in lieu of the standard masthead and sidelight arrangement?
Answer: An all-round white light and sidelights. The rule allows smaller vessels under 12 meters to simplify their lighting by using an all-round white light combined with sidelights instead of separate masthead lights.
33 CFR § 83.23(d): “A power-driven vessel of less than 12 meters in length may, in lieu of the lights prescribed in paragraph (a) of this Rule, exhibit an all-round white light and sidelights.”
20. What specific information regarding the operator's background must be included in the casualty report?
Answer: Vessel operating experience and boating safety training. The regulation specifically requires the inclusion of the operator's vessel operating experience and boating safety training details.
33 CFR § 173.57(b): “Name, address, age, or date of birth, telephone number, vessel operating experience, and boating safety training of the operator making the report;”
21. Under what specific condition is a recreational vessel less than 26 feet in length, propelled by an outboard motor, exempt from carrying portable fire extinguishers?
Answer: If the construction of the vessel will not permit the entrapment of explosive or flammable gases or vapors. The regulation states that small outboard-powered boats are exempt from carrying extinguishers only if their design prevents gas entrapment.
33 CFR § 175.320(a): “A vessel less than 26 feet in length, propelled by an outboard motor, is not required to carry portable fire extinguishers if the construction of the vessel will not permit the entrapment of explosive or flammable gases or vapors.”
22. You are operating a power-driven vessel on the Great Lakes, proceeding downbound with a following current, and you meet an upbound vessel on a reciprocal course. How does the standard head-on rule apply to this situation?
Answer: The downbound vessel has the right-of-way over the upbound vessel. On specified waters like the Great Lakes, the vessel moving with the current (downbound) has priority over the vessel moving against the current (upbound).
33 CFR § 83.14(d): “Notwithstanding paragraph (a) of this Rule, a power-driven vessel operating on the Great Lakes, Western Rivers, or waters specified by the Secretary, and proceeding downbound with a following current shall have the right-of-way over an upbound vessel”
23. How must the spacing be formatted between the letter and number groupings of a vessel number?
Answer: With spaces or hyphens equal to the width of a letter other than 'I' or a number other than '1'. The rule specifies that separators must match the width of standard characters, excluding the narrow 'I' and '1' to ensure legibility.
33 CFR § 173.27(a): “Have spaces or hyphens that are equal to the width of a letter other than “I” or a number other than “1” between the letter and number groupings”
24. What requirement applies to the mounting of a 160-B semi-portable fire extinguisher on a recreational vessel over 300 gross tons?
Answer: Its frame or support must be welded or otherwise permanently attached to a bulkhead or deck. The regulation mandates that these specific extinguishers be permanently secured to structural elements like bulkheads or decks.
33 CFR § 175.320(b): “The frame or support of each 160-B semi-portable fire extinguisher required by paragraph (b)(2)(ii) of this section must be welded or otherwise permanently attached to a bulkhead or deck.”
25. Who is authorized to direct an individual operating a vessel to undergo a chemical test when reasonable cause exists?
Answer: A law enforcement officer or a marine employer. The rule specifically limits the authority to direct a test to law enforcement officers and marine employers.
33 CFR § 95.035(a): “Only a law enforcement officer or a marine employer may direct an individual operating a vessel to undergo a chemical test when reasonable cause exists.”
