What to do at a Detour Sign
Follow the marked route around a road closure or work zone.
- Recognize the sign by its rectangle shape and orange/black color combination.
- Adjust your speed and lane position based on the message above.
- Watch for related signs and pavement markings nearby.
warning Common Test Mistakes
On the written exam, applicants frequently miss questions that:
- Confuse a rectangle 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.
