What CEVNI Is
CEVNI is the European Code for Inland Waterways. It sets a common pattern for traffic rules, vessel signals, waterway signs, sound signals, and conduct on many European inland waterways.
For revision, the important shift is this: you are not studying open-sea COLREGs in isolation. You are learning how inland signs, local directions, locks, bridges, commercial traffic, and restricted channels change the skipper's decisions.
- CEVNI is about inland waterway traffic rules and signals.
- The syllabus includes signs, lights, buoyage, sound signals, and regulations.
- It does not replace local waterway directions or national requirements.
- Small-craft skippers must be able to recognise the cue and take the required action.
| Area | What to revise | Practical use |
|---|---|---|
| Signs | Prohibitions, obligations, restrictions, information | Know whether entry, passing, speed, berthing, or direction is controlled |
| Lights and shapes | Vessel status, danger markings, lock and bridge lights | Recognise traffic that is constrained, stopped, dangerous, or permitted to proceed |
| Traffic rules | Meeting, overtaking, crossing, narrow water, priority signals | Avoid conflict before vessels become committed in a restricted channel |
| Local rules | Waterway notices, lock-keeper directions, national variations | Check the current instruction for the actual waterway you are using |
Watch for this: Treat every sign, light, or sound signal as an instruction that changes what you do next.

How It Connects to the ICC
UK boaters commonly meet CEVNI through the International Certificate of Competence. If an inland category is required on the ICC, the CEVNI test is used to show knowledge of inland traffic regulations, signage, buoyage, and signals.
A CEVNI pass is not a stand-alone navigation licence. It supports the inland endorsement context; it does not remove the need to meet the wider eligibility, competence, vessel, country, or waterway requirements that apply to the trip.
- CEVNI revision supports the inland ICC context.
- The CEVNI test is multiple choice and focused on inland-waterway rules.
- The test is separate from practical boat handling.
- Country and waterway authorities can still impose additional rules.
Common questions
Is CEVNI a licence?
No. It is a rules-and-regulations assessment used in the inland ICC context. The boat, skipper, country, and waterway may still have separate requirements.
Why is local checking still needed?
CEVNI provides a common inland-waterway code, but national regulations, harbour or lock instructions, notices, and temporary restrictions can change the action required on the day.

Where CEVNI Thinking Starts
Inland-waterway boundaries are not always obvious from the chart alone. CEVNI signage is a strong cue that you have moved into an inland traffic environment, and the first lock, bridge, barrage, or other obstacle to seagoing ships often marks the change.
The safe habit is to identify the waterway type before arrival. Check the harbour or navigation authority, local notices, lock information, and any country-specific requirements before you commit to the route.
- Do not assume coastal habits apply unchanged inland.
- CEVNI signage is a cue that inland rules may apply.
- Locks, bridges, barrages, and river mouths can mark the practical boundary.
- When in doubt, check the local harbour master or navigation authority.

Revision Standard for This Course
A good answer is not just the name of a sign or rule. It must say what the skipper should do: stop, keep clear, call, wait, pass only in the marked opening, reduce wash, avoid berthing, or follow a traffic light.
Use this course as an applied revision guide. For every item, ask: What is the cue? What does it prohibit, require, limit, or permit? Which vessel has less room or less ability to manoeuvre? What local instruction could override my assumption?
- Name the cue.
- Classify the cue: prohibition, mandatory instruction, restriction, recommendation, or information.
- State the required action.
- Check whether local instructions or commercial traffic change the plan.
Watch for this: If your answer does not change the helm, speed, track, waiting position, or communication plan, it is probably not complete enough.
