Inland waterway traffic rules

Inland waterway traffic is governed by the Law on Inland Waterway Navigation and its implementing documents. The key difference from road traffic is that vessels cannot stop quickly, so every rule favours giving way early.

Who gives way

• A vessel going against the current gives way to one going with it where the fairway is narrow.
• Small, manoeuvrable craft give way to large or unwieldy vessels and to towed convoys.
• Non-powered craft give way to powered vessels.

Passing and overtaking

When passing, the general rule is to keep to your own starboard side. To overtake, the overtaking vessel must sound the signal and may proceed only once the vessel ahead has agreed and the fairway is wide enough.
