What is the meaning of the following traffic sign?

- Maintain your current speed.
- Drive faster in order to clear the intersection.
- Portable traffic sign ahead.
- Correct answer: Caution, traffic light ahead.
Why this is the answer
The correct answer in the official bank: Caution, traffic light ahead.
A triangular warning sign with a red border announces that there is a traffic light ahead. So slow down, stay alert and be ready to stop if the light changes. The sign does not tell you to drive faster in order to clear the intersection, nor to keep your current speed without paying attention to the traffic light.
