I carry charts and try to be well aware of things like that.

Another factor may be the area you sail in. My home port has traffic
lanes marked in 'magenta colour' on the charts. Pleasure boats are
supposed to cross them at right angles as quickly as possible.
Most people don't...but if a major commercial vessel..such as a post
panamax containership comes in...we get out of the way.
