A more thorough explanation:

The International Regulations for Preventing Collisions at Sea, also known as the International Rules of the Road, are a set of rules that govern the behavior of vessels at sea to prevent collisions. These rules are agreed upon by the International Maritime Organization (IMO) and are followed by all ships and boats on the high seas.

For example, one of the rules states that vessels must keep a lookout at all times and take action to avoid a collision. Another rule requires vessels to use lights and signals to communicate their position and intentions to other vessels. These rules are designed to ensure the safety of all vessels and their crews.

These regulations are important because they help prevent accidents and collisions at sea, which can be dangerous and even deadly. By following these rules, ships and boats can navigate safely and avoid collisions with other vessels.
