The traffic sign "Time indications hours without restriction to weekdays" (1040-31) indicates the times during which certain restrictions apply, without specifying any limitations to weekdays.

This sign typically displays two sets of times, which define periods when specific regulations (like no parking, no stopping, etc.) are in effect. For example, if the sign shows “8:00 - 18:00”, it means the restrictions apply every day from 8 AM to 6 PM, regardless of whether it's a weekday or a weekend.

Always pay attention to such signs to ensure you comply with the indicated times and avoid possible fines. If you have any more questions about this sign or other traffic rules, feel free to ask!
