You want to overtake a truck with a trailer. What must you be aware of when doing so?

Your answer is correct because when overtaking a truck with a trailer in Germany, you must be aware of two main points:

1. The required overtaking distance is significantly increased due to the length of the trailer. This means you need more space and time to safely pass because the vehicle combination is longer than a standard truck.

2. The external bodywork of the truck-trailer combination can block your view of vehicles ahead. This hidden area means you might not see other vehicles or obstacles directly in front of the truck, so extra caution is necessary.

The third option is incorrect because you are allowed to start overtaking before you are directly behind the truck-trailer combination, as long as it is safe and legal to do so. Waiting until directly behind can unnecessarily delay the overtaking maneuver.

Understanding these points helps ensure safe overtaking maneuvers around large and long vehicles on German roads.
