The sign "Time indications hours with restriction to weekdays" (sign number 1042-33) indicates that specific restrictions apply to certain activities, such as parking, during the hours specified on the sign, and that these restrictions are only in effect on weekdays.

Typically, this sign will display the exact hours during which the restrictions apply. For example, it might say "Mon-Fri 8:00 - 18:00", meaning that between 8 a.m. and 6 p.m. on weekdays, you must adhere to the restrictions indicated, such as not parking or only parking with a permit. On weekends and public holidays, the restrictions are not in effect, and you are generally free to park without concern regarding the sign.

Always make sure to pay attention to the exact time indicated and the days of the week, as failing to comply can lead to fines or towing of your vehicle.
