What must you be aware of when driving your lorry through narrow passageways?

Your selected options are correct because they highlight important considerations for driving a lorry through narrow passageways.

1. The exterior rear-view mirrors extending beyond the vehicle width means they need to be accounted for when assessing whether the vehicle can safely navigate a narrow space. Failing to consider them can lead to collisions with obstacles or walls.

2. The body of the lorry swaying on uneven surfaces can also affect stability and space requirements when maneuvering. It is crucial to be aware of how the vehicle's dimensions change in practical scenarios, ensuring you leave enough room to prevent accidents.

Therefore, both points are essential for safe navigation in tight areas, aligning with German traffic regulations that emphasize safety and spatial awareness when operating larger vehicles. Understanding these aspects helps prevent accidents and promotes responsible driving behavior.
