Crossings test whether you recognise vulnerable road users early and adjust speed before the situation becomes urgent.
You should recognise crossing types, approach under control and give pedestrians or cyclists the priority required by the crossing.
These examples are for understanding and practice; they are not a promise that a particular mistake will always receive a particular grade.
Arriving too quickly at a crossing and braking sharply for someone already crossing.
Failing to notice somebody waiting or moving into the crossing area.
