Are you obliged to make sure that all passengers have left the tram, before entering into the depot?

In the photo we see the inside of an empty tram. You are obliged to make sure that all passengers have got off the tram before you enter the depot area - the answer is YES.

A depot is a site of the transport company where trams are parked, washed and repaired, and passengers are not allowed to be there. A person who has fallen asleep or has not managed to get off could be locked in the tram or get injured in the depot area. That is why, at the last stop before going to the depot, the tram driver checks the inside of all the coaches, and only then enters the depot. You tell the dispatcher about passengers who do not want to leave the tram.
