The sign labeled "Prohibition for motor vehicles exceeding the specified actual width" indicates that motor vehicles that exceed a certain width limit are not allowed to enter or proceed on that road. This is often put in place to ensure safety on narrow roads or areas where large vehicles may have trouble maneuvering without causing hazards.

When you see this sign, you need to pay attention to the specified width shown on the sign and make sure that your vehicle does not exceed that measurement. If your vehicle is wider than the given limit, you must find an alternative route that accommodates larger vehicles.

Always stay aware of the dimensions of your vehicle and adhere to such restrictions to avoid penalties and ensure road safety for all users.
