The sign you mentioned, "Prohibition of overtaking for motor vehicles of all kinds," indicates that vehicles are not permitted to overtake any other vehicles on the stretch of road where this sign is displayed.

This rule is typically enforced in areas where overtaking could pose safety risks, such as near intersections, pedestrian crossings, or places with limited visibility. It helps to prevent accidents and ensure the safety of all road users.

Drivers must adhere to this prohibition even if they are driving a vehicle that is usually allowed to overtake under normal conditions. If you see this sign, you should maintain your speed and wait until you are in a zone where overtaking is permitted.
