warning Common Test Mistakes
On the written exam, applicants frequently miss questions that:
- Confuse a diamond shape with a similar one (e.g. octagon vs hexagon).
- Mistake the meaning of color (red = prohibition; yellow = caution; green/blue = guidance).
- Skip the action requirement — knowing what a sign means isn't the same as knowing what to do.
