Final answer:
The sign displays the maximum speed allowed for day and night driving.
Step-by-step explanation:
The sign tells about the maximum speed allowed for day and night driving. The speed limit displayed on the sign indicates the highest speed that drivers are legally allowed to travel on the road. For example, if the sign displays a maximum speed limit of 60 km/hr, it means that drivers should not exceed 60 km/hr for both day and night driving.
