What is the meaning of the traffic sign in the following picture?

- It is a speed restriction that is intended for private vehicles only.
- The vehicle’s driving speed should not be lesser than 40 KPH.
- It is a speed restriction that is intended for two-wheelers and trolleys.
- Correct answer: The vehicle’s driving speed should not exceed 40 KPH.
Why this is the answer
The correct answer in the official bank: The vehicle’s driving speed should not exceed 40 KPH.
A round sign with a red border and a number inside sets a maximum speed, and it applies to all vehicles on the road from where it stands. So you must not exceed 40 KPH, and even below that you should adjust your speed to road conditions. The sign is not aimed at any particular type of vehicle, and it does not set a minimum speed; a minimum speed sign is blue.
