Expected outcome / competence

Signals should be given clearly to let other road users know the intended course to be taken. Signals shown in the Highway Code should only be used, if it would help other road users (including pedestrians).

Signals should be given in good time and cancelled after the manoeuvre has been completed.

Pedestrians should not be beckoned to cross the road.
