What is the maximum permissible width of this truck tractor with mounted implement?

Your answer is correct. According to German traffic regulations, the maximum permissible width for agricultural vehicles like this tractor with an attached implement is generally 3.0 meters. This limit ensures safety on public roads, preventing vehicles from being too wide to travel without causing hazards or obstructing other vehicles. If the vehicle or its attachments exceed this width, additional safety measures such as special signage, escort vehicles, or travel restrictions may be required. Remembering this 3.0-meter width limit will help you recognize when special precautions are necessary for wide agricultural machinery on public roads.
