The convention certainly is that aircraft leaving the active runway after landing are considered to have right of way.
In UK, Rules of the Air Regulations (see Section 2 of
CAP393) states the following:
SECTION 7
AERODROME TRAFFIC RULES
Right of way on the ground42.
...(3) Flying machines and vehicles shall give way to aircraft which are taking off or landing.

These comments are correct in principle, but are not really relevant to the question. I think you are both misunderstanding the point that
da42flyer was trying to make, which was to ask what is the legal (default) position,
unless otherwise cleared by an ATC unit.
In any event, neither comment is fully correct, as they both assume there is an ATC unit at the airfield. The legal position still exists - and indeed is even more important - at an airfield where there is either only an Air/Ground service or no ATS unit at all.
