When you approach an intersection, and you can't see after you have stopped, tell the testing officer you are moving a little bit forward to see.
Don't just move forward - they might think you are taking off.
If there are vehicles coming from the left and you can sort of see them, wait for them to pass and then tell the testing officer you are moving forward to see.
