Align title to the left, and add logo to the top right • The logo should not be too large, but it should be visible at all time • Adding it to the right, makes it secondary in the visual hierarchy so that it is not compete with the rest of the text 51

The cars coming from the other directions will not have to stop. • This sign was put here by the authorities in charge. • This sign concerns vehicles only.

The result is lots of bullet points and lots of text. However, lots of text competes with the spoken words because we can just read faster than we speak. And we want the audience to hear what we have to say. Another option is to put the text in the notes and provide slides with notes for as printouts.
