TV03 Master/Mate/Apprentice Mate of Towing Vessels Western Rivers is modular: Inland Rules (Q300, 90%), Deck General (Q423, 70%), Deck Safety (Q424, 70%), Navigation General Western Rivers (Q425, 70%), Chart Plot (Q426, 90%), and TV WR Renewal OBE (Q427, 90% when assigned). Lower-level original fees are about $100+$95+$45 under 46 CFR 10.219. Service and TOAR follow 46 CFR 11.463–11.466. This free bank is an English MCQ study aid focused on river towing, barge fleets, locks, bridges, and Western Rivers special rules.

Sample USCG Towing Western Rivers Practice Questions

Try these sample questions to test your USCG Towing Western Rivers exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under the Inland Navigational Rules, a proper lookout on a towing vessel must be maintained by:

A.Radar alone when the river is foggy

B.Sight and hearing as well as by all available means appropriate to the circumstances

C.The master only when the tow is more than 15 barges

D.VHF monitoring unless the vessel is in a lock

Explanation: Rule 5 requires every vessel to keep a proper lookout by sight and hearing and by all available means appropriate to the circumstances so as to make a full appraisal of the situation and of the risk of collision—critical on a river towboat with limited visibility over a long tow.

2You observe another vessel by compass bearing while closing range on a river. The bearing remains nearly steady. What should you assume?

A.There is no risk because the bearing is not changing

B.Risk of collision exists

C.Only the other vessel has collision responsibility

D.The other vessel must be overtaking you

Explanation: A steady or nearly steady bearing with decreasing range is a classic indicator of collision risk under Rule 7. Assume risk of collision exists and take appropriate action early—especially important with limited maneuverability of a loaded tow.

3Two power-driven vessels are crossing so as to involve risk of collision. Which vessel is the give-way vessel under the Inland Rules?

A.The vessel that has the other on her own port side

B.The smaller of the two vessels

C.The vessel that has the other on her own starboard side

D.The vessel with fewer barges

Explanation: Under Rule 15, when two power-driven vessels are crossing, the vessel which has the other on her own starboard side shall keep out of the way and, if the circumstances of the case admit, avoid crossing ahead of the other vessel. Western Rivers special privileges are separate situations.

4Under Inland Rule 14, when two power-driven vessels are meeting head-on so as to involve risk of collision, each vessel shall:

A.Alter course to port and pass starboard to starboard

B.Stop engines until the situation clears

C.Alter course to starboard so that each passes on the port side of the other

D.Sound five short blasts and maintain course

Explanation: Inland Rule 14 requires each power-driven vessel in a head-on meeting involving risk of collision to alter course to starboard so that each shall pass on the port side of the other—unless Western Rivers special provisions or other applicable rules dictate a different arrangement.

5Under Rule 13, once a vessel is an overtaking vessel, any subsequent change of bearing between the two vessels:

A.Does not relieve her of the duty to keep clear until she is finally past and clear

B.Converts the situation into a crossing situation once the bearing opens

C.Makes her the stand-on vessel as soon as she is abeam

D.Ends her obligations the moment the other vessel's sternlight is no longer visible

Explanation: Rule 13 states that any subsequent alteration of the bearing does not make the overtaking vessel a crossing vessel or relieve her of the duty to keep clear until finally past and clear. On a river this matters when a boat comes up on a tow and then draws out abeam.

6Under Inland Rule 9, which power-driven vessel holds the right-of-way when two power-driven vessels meet in a narrow channel or fairway on the Western Rivers?

A.The vessel proceeding upbound against the current

B.The vessel with the deeper draft only

C.The vessel proceeding downbound with a following current

D.The vessel with fewer barges

Explanation: Inland Rule 9 (33 CFR 83.09(a)(ii)) gives a power-driven vessel proceeding downbound with a following current the right-of-way over an upbound vessel in narrow channels or fairways on the Great Lakes, Western Rivers, or waters specified by the Secretary. A vessel running with the current has far less ability to stop or hold, which is why the rule puts the initiative with her.

7Under Inland Rule 34, one short blast when vessels are in sight of one another generally means:

A.I am altering my course to port

B.I am operating astern propulsion

C.Danger; I do not understand your intentions

D.I intend to leave you on my port side (Inland intention/agreement signal for a port-to-port pass when applicable)

Explanation: On Inland waters, one short blast is used as an intention/agreement signal meaning 'I intend to leave you on my port side' (pass port-to-port when applicable). Know the Inland intention-signal system for TV03 Q300.

8Five or more short and rapid blasts on the whistle means:

A.I am operating astern propulsion

B.I intend to overtake you on your starboard side

C.Doubt or danger — I do not understand your intentions or I doubt whether sufficient action is being taken

D.Request for a lockage

Explanation: Rule 34 provides that at least five short and rapid blasts is the danger or doubt signal when vessels are in sight and one vessel fails to understand the intentions or actions of the other, or is in doubt whether sufficient action is being taken to avoid collision.

9Three short blasts on the whistle when vessels are in sight means:

A.I intend to leave you on my starboard side

B.I am operating astern propulsion

C.I am altering course to starboard

D.Danger; keep clear

Explanation: Rule 34 provides that three short blasts means 'I am operating astern propulsion.' Towboats commonly use this when backing to check way or position the tow.

10In restricted visibility, a power-driven vessel making way through the water shall sound at intervals of not more than two minutes:

A.One short blast

B.One prolonged blast

C.Two prolonged blasts

D.Three short blasts

Explanation: Rule 35(a) requires a power-driven vessel making way through the water to sound one prolonged blast at intervals of not more than two minutes in or near an area of restricted visibility.

USCG Towing Western Rivers Study Tips from Top Performers

1Overprepare for Inland Rules of the Road because Q300 requires 90% to pass.

2Master Western Rivers special rules: downbound privilege with a following current, narrow-channel duties, and Inland Rule 34 intention/agreement signals.

3Drill lights and shapes for power-driven vessels, towing vessels, barges, and push-mode configurations—core river tow traffic pictures.

4Practice lock procedures, current effects, bank suction, bridge clearances, and shallow-water handling for towing vessels and tows.

5Know barge-fleet makeup, face wires, wing wires, jockey wires, and safe line/wire handling around the tow.

6Study girting, stern-towing hazards, and emergency procedures unique to towing operations.

7Drill chart-plot routines for Q426: speed-time-distance, set and drift, compass error, and standard plotting symbology—pass is 90%.

8Take timed sets that match REC module length for Q423 and Q424 (50 questions each at 70%).

9Review firefighting, pollution reporting, PFDs, man overboard, and abandon-ship for deck safety.

10Confirm your application path is TV03 (Western Rivers towing) rather than Oceans/NC or Great Lakes and Inland towing modules.

11Know that Inland-only Rules (Q300) may place a COLREGS geographic limitation on the MMC unless International Rules are also completed when required.

Frequently Asked Questions

How many questions are on the USCG TV03 exam?

Published modules include Rules of the Road Inland (Q300), Deck General (Q423 — typically 50 at 70%), Deck Safety (Q424 — typically 50 at 70%), Navigation General Western Rivers (Q425), Chart Plot (Q426 — typically 10 at 90%), and TV Western Rivers Renewal OBE (Q427 when assigned). Exact totals depend on the current NMC module sizes; confirm sample exams on the TV03 NMC page.

What passing score do I need?

Most modules require 70%. Rules of the Road Inland (Q300) requires 90%. Chart Plot (Q426) requires 90%. The TV Western Rivers Renewal OBE (Q427) requires 90% when assigned for renewal.

How much does the exam cost?

Under 46 CFR 10.219, a typical original lower-level officer path is about $100 evaluation, $95 examination, and $45 issuance (~$240 total). Medical, drug testing, TOAR courses, and training costs are separate. Pay via Pay.gov.

Can I take the exam remotely?

No. These deck officer modules are administered in person at U.S. Coast Guard Regional Exam Centers (RECs). There is no approved remote-testing option for these endorsements.

Is TV03 the same as Master Rivers 100 GRT?

No. TV03 is the towing-vessel Western Rivers path (Master/Mate/Apprentice Mate of Towing Vessels). Master of less than 100 GRT on rivers uses a different NMC path (RVR05). Do not mix route- or endorsement-specific modules.

What regulation covers Master, Mate, and Apprentice Mate of Towing Vessels?

46 CFR 11.463 provides general requirements. 46 CFR 11.464 covers Master of Towing Vessels, 11.465 covers Mate (Pilot) of Towing Vessels, and 11.466 covers Apprentice Mate of Towing Vessels. Western Rivers service and observation/training rules are specified in those sections and current NMC checklists.

What is Q427 TV Western Rivers Renewal OBE?

Q427 is the open-book exercise (OBE) module associated with Western Rivers towing renewal. It is scored at an elevated pass standard (typically 90%) when assigned. Original applicants focus primarily on Q300 and Q423–Q426 as listed for their path.

What calculator can I bring?

The NMC policy letter of December 2, 2024 superseded the earlier TI-30XIIS-only rule. At a Regional Exam Center you may use a programmable calculator with memory if all programs and memory are cleared before entry and you can demonstrate clearing with the manufacturer's instructions. If the examiner cannot confirm the device is cleared, a TI-30XIIS is provided instead. Only one calculator is allowed; other electronics including smart watches are not permitted.

Is this free practice bank an official Coast Guard exam?

No. This is a free English-language multiple-choice study aid for exam prep. Official modules are administered by the Coast Guard at RECs and may include chart-plot and calculation items that this bank approximates with knowledge and calculation MCQs. It is not an official Coast Guard examination and does not replace REC testing or TOAR requirements.
