An agricultural implement has a transport width between 2.55 metres and 3.00 metres. What are the legal requirements for driving it on public roads in Austria?

1. It requires an individual permit from the Landesregierung for each journey
2. It is permitted for agricultural and forestry operations provided it carries red-and-white warning panels and clearance lights in poor visibility
3. It is permitted only outside built-up areas and only in daylight
4. It is permitted without any marking, because agricultural vehicles are exempt from width rules
