The purpose of your presentation is to communicate facts efficiently. Meaningless pictures or phrases waste valuable learning energy. Include a picture of the intersection. A photograph of the pedestrian as the witness describes the woman who was injured. Extra words waste time and blur memory.
Fonts Think once again of that road sign.
Imagine if it were written in decorative script. Keep it simple, and clean. Use san serif fonts, such as Arial or Helvetica. These are clear and comfortable to the eye. Highlight key phrases.
