You are driving an agricultural machine. A queue of cars has formed behind you. What is correct?

You are correct that when driving an agricultural machine and a queue of cars forms behind you, you should reduce your speed at a suitable place or stop if necessary to let the faster vehicles overtake. This rule helps maintain smooth traffic flow and prevents frustration or risky overtaking maneuvers by other drivers. Agricultural machines generally move slower, and allowing cars to pass when safe is both considerate and required by German traffic regulations. Using hazard warning lights or ignoring overtaking is not appropriate in this situation.
