If you are driving an overnormative vehicle with the length exceeding 23 m, are you obliged to be piloted by assisting pilot vehicles?

According to the regulations, an abnormal vehicle whose length exceeds 23 metres must be escorted by at least one pilot vehicle. This requirement arises from the need to ensure the safety and flow of road traffic, as such a long vehicle combination creates significant difficulties, especially on narrow and winding roads, such as the one in the photograph.
