Question

In D&D (dungeons and dragons) does the DM ask for perception check when you enter a room or do you have ask to

Answer 1

he does when you look for traps

Answer 2

It is the player's job to bring up things like this. Some GM's however, will go ahead and make rolls for things like that if there is something noteworthy in the room.

Answer 3

If there is something that he thinks you may not notice when entering a room, he may roll it himself but most DM's I've gamed with will ask the player to make a perception roll.
