Correct answer
Slow down or move onto a practicable shoulder to let following traffic pass.
Slow down or move onto a practicable shoulder as soon as possible to let traffic pass, under Article 86.3. Merely moving to the kerb or inviting another driver to overtake is insufficient when it is unsafe. Keep to the right edge where required without accelerating or obstructing overtaking. An arm or indicator invitation applies only when overtaking can be safe despite being unable to keep fully right.
