Where:
This sign is placed below a regulatory road sign on any public road.
It acts as an additional instruction to the main sign above it.

Purpose:
The Time Limit Sub-Group sign indicates that the rules of the main sign only apply during the specific times, days, or conditions shown on the sub-sign.

For example,
    a No Parking sign with a Time Limit Sub-Group may mean No Parking from 07:00 to 17:00, but outside those hours parking is allowed.

Action:
Read and follow the times or conditions displayed.
The rule shown on the main sign is not always in effect. It depends on what is written on the time limit board.

    Make sure to check;
    Start and end times
    Days of the week, if indicated
    Special conditions (e.g., "School Days Only")
    Failing to observe the time limit may result in a fine, even if the road appears clear.
