If you are driving an overnormative vehicle with the length exceeding 30 m, are you obliged to be piloted by two assisting pilot vehicles?

In accordance with current regulations, an abnormal vehicle combination whose length exceeds 30 metres must be escorted by two pilot vehicles. The situation shown in the picture, the transport of an oversized bridge component, is an example of such a journey. In such a case, one pilot vehicle travels at the front and the second at the rear of the convoy to ensure the safety of all road users.
