In this situation, should the driver anticipate that a child might suddenly run onto the road from behind the vehicle?

The presence of an adult with children on the pavement is a signal for the driver to exercise particular caution and apply the principle of limited trust. The behaviour of children can be unpredictable, and they may run out into the carriageway at any moment. A parked vehicle further restricts visibility, which increases the risk that a child may run out from behind it directly into the path of an oncoming vehicle.
