What is a common general rule for speed in heavy traffic?

• A. Increase speed to reduce time in traffic.
• B. Maintain speed if you have right of way.
• C. Slow down to allow safe detection and reaction time and give yourself space to maneuver.
• D. Stop abruptly to avoid collision.

Answer: (C)

In heavy traffic you want to proceed at a pace that gives you enough time to spot risks, assess them, and maneuver if needed. Slowing down provides safer detection and reaction time plus the space to avoid or steer around other vessels. Increasing speed reduces your ability to see and respond, and can force abrupt moves that endanger others. Maintaining speed because you think you have the right of way ignores the density of traffic and potential for sudden changes, while stopping abruptly can surprise nearby vessels and create new hazards. So the best approach is to slow down and maintain a safe margin for maneuvering. This matches the idea of proceeding at a safe speed under the prevailing conditions.
