description: The edge of a road is obvious to a car’s driver, but the pilot at sea has to rely on lateral buoys to let him know where it is safe to steer. Lateral buoys are marked in red or green, with specially shaped tops, to differentiate the port (left) and starboard (right) edges of shipping channels. Thanks to lateral buoys, tankers navigating through shallow waters are able to keep from running aground and container ships chugging through busy harbours stay in their lanes.
