Why should you not overtake the moped rider in this situation?

Your answer is correct because all three reasons are important according to German traffic rules when dealing with mopeds in narrow or hazardous situations.

1. Protecting the moped rider from falling is crucial since mopeds are less stable than cars. Sudden overtaking, especially in confined spaces, can cause turbulence or force the rider off balance.

2. You are not allowed to drive significantly faster than the moped rider in such conditions. This rule aims to prevent dangerous speed differences, which can increase the risk of accidents.

3. If you cannot maintain enough side clearance during overtaking—especially in narrow lanes or construction zones—overtaking is prohibited. Safety requires sufficient lateral space to avoid collisions or forcing the moped off the road.

Together, these rules ensure the safety of both car drivers and vulnerable road users like moped riders, especially in confined or potentially hazardous areas such as construction zones. Understanding these principles helps you recognize when overtaking is unsafe or illegal.
