What should a tram driver do upon sudden appearance of a vehicle on the tracks directly in front of the tram?

The primary duty of the tram driver is to ensure the safety of passengers and other road users. In the event of a vehicle suddenly entering the tramway, the only effective method of avoiding or minimising the consequences of a collision is immediate and decisive braking. Due to the tram's large mass and long braking distance, any other reaction would be ineffective and would pose a direct threat to life.
