What to do at a No Left Turn Sign
Left turns are prohibited at the intersection ahead.
- Recognize the sign by its square shape and black/white 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 square 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.
