What to know for Lights and Day Shapes

Use lights and shapes to identify vessel type, status, and likely constraints on inland waterways.

Inland vessel lights, shapes, special signals, and restricted manoeuvrability indicators. This module is mapped to the published course boundary for CEVNI and Inland ICC Revision and written as an independent revision aid, not official training material.

Key Points

  • Lights and shapes communicate status before close quarters
  • Commercial craft may show additional signals
  • Restricted vessels need more room and early planning
  • Night recognition needs repeated visual practice
