rules of Part B, Sections I1 and 111, if risk of collision with
another ship is deemed to exist.
5. At junction points where traffic from various directions meets, a
true separation of traffic is not really possible, as ships may need
to cross routes or change to another route. Ships should therefore
navigate with great caution in such areas and be aware that the
mere fact that a ship is proceeding along a through-going route
gives that ship no special privilege or right of way.
6. A deep-water route is primarily intended for use by ships which,
because of their draught in relation to the available depth of
water in the area concerned, require the use of such a route.
Through traffic to which the above consideration does not apply
should, as far as practicable, avoid using deep-water routes.
7. Precautionary areas should be avoided, if practicable, by passing
ships not making use of the associated traffic separation schemes
or deep-water routes, or entering or leaving adjacent ports.
8. In two-way routes, including two-way deep-water routes, ships
should as far as practicable keep to the starboard side.
9. Arrows printed on charts in connection with routeing systems
merely indicate the general direction of established or recom-
mended traffic flow; ships need not set their courses strictly
along the arrows.

10. The signal YG meaning You appear not to be complying with the
trafic separation scheme is provided in the International Code
of Signals for appropriate use.
Trafic separation schemes
Paragraph (a) of Rule 10 makes it clear that the Rule only applies to
traffic separation schemes adopted by IMO (see page 72).
The words ‘and does not relieve any vessel of her obligation under
any other Rule’ were added to Rule 10(a) by the 1987 amendment.
This change was made to make it quite clear that all other Rules of
the Collision Regulations continue to apply to a vessel using a traffic
separation scheme. For instance, a power-driven vessel following a
traffic lane is not relieved of her obligation to keep out of the way of
a vessel seen on her own starboard side to be crossing so as to involve
risk of collision.
