Why are you particularly at risk, if you are riding a two-wheeler?

Your answer is correct because all three points explain important risks for two-wheeler riders in German traffic rules. First, two-wheelers can be easily overlooked by other drivers due to their smaller size, increasing the chance of collisions. Second, their speed is often underestimated by other road users, which can lead to misjudgments in traffic situations. Lastly, if an accident occurs, riders of two-wheelers are more vulnerable to serious injuries because they have less physical protection compared to cars. Understanding these risks helps riders stay more cautious and prepared on the road.
