You wish to overtake a farm tractor with a mounted implement extending beyond its back. What must you remember?

Your selected combination is correct because it emphasizes critical safety considerations when overtaking a farm tractor.

1. The mounted implement can swing out when the tractor turns off: This is crucial because it highlights the risk of the implement encroaching into the lane, potentially leading to a collision if not anticipated.

2. The rear lights may be heavily soiled or concealed: This is important since visibility of direction signals can be compromised, meaning you may not see the tractor's intention to turn or signal until it is too late, thereby increasing the risk during overtaking.

These considerations are part of ensuring safety on the roads as outlined in German traffic laws, which mandate that drivers must always be aware of the limitations and specific risks associated with larger vehicles like farm tractors. Always prioritizing safety while overtaking helps prevent accidents.
