You See a White Buoy With an Orange Square and Black Lettering. What Does This Buoy Tell You?

The answer

A white buoy with an orange square and black lettering is an information marker. It belongs to a family of markers called non-lateral markers, which give you information rather than telling you which side of a channel to pass on. The orange square is the key: it signals that the black text inside or beside it is providing general information — the name of a place, directions, distances, or the location of facilities such as a marina, fuel dock, or public landing. Reading the lettering ("MARINA," "GAS," "CAMP") tells you what the marker is pointing you toward.

The important takeaway for the exam: an orange square never means danger or a rule. It is purely informational, like a roadside sign that says "Rest Area 2 Miles."

Why the other options are wrong

This question is designed to test whether you can tell the four orange symbols apart. Each orange shape carries a distinct meaning, and choosing the wrong one is the classic mistake:

• Orange diamond (danger) — An orange open diamond warns of a danger such as rocks, a dam, a stump, or shoal water. If the buoy had a diamond, the answer would be "danger," not information.
• Orange diamond with a cross inside (boats keep out) — This means the area is closed to all boats, for example a swimming area or spillway. It is a restriction, not information.
• Orange circle (controlled area) — A circle marks a controlled or regulated area, such as a no-wake zone, speed limit, or ski-only zone, with the rule written inside.
• "It marks the channel edge" — Wrong category entirely. Channel sides are marked by lateral red and green markers, not white-and-orange non-lateral markers.

Because only the square means "information," that is the correct interpretation for this buoy.

The bigger picture

The U.S. Aids to Navigation System splits markers into two groups. Lateral markers (red and green) define the edges of a channel and tell you which side to pass. Non-lateral markers — white buoys or signs with orange symbols — give safety and information messages. Memorizing the four orange shapes prevents dangerous confusion on the water:

• Square = information (directions, facilities, locations)
• Circle = controlled area (a rule you must obey)
• Open diamond = danger (avoid the hazard)
• Crossed diamond = keep out (no boats allowed)

A reliable memory hook: a square is a "sign" giving you facts, a circle means an activity is "regulated" inside it, and a diamond is sharp and "dangerous" — with a cross through it meaning "do not enter at all." With those four straight, you can read any orange marker at a glance.
