To your tractor you have attached a hay turning machine that projects a long way to the back. Who could be endangered by this when you take a left turn?

In this scenario, when you take a left turn with a tractor and a hay turning machine that extends to the back, several road users could be endangered. The selected options, "vehicles that have pulled in alongside to my right" and "pedestrians on the right-hand side of the road," are correct because:

1. Vehicles on your right might be in your blind spot or too close, making them vulnerable to being hit as your vehicle swings wide during the turn.
2. Pedestrians on the right-hand side could also be at risk as the rear of the hay turning machine might extend into their path as you turn.

It's important to consider these risks to comply with German traffic regulations which emphasize the safety of all road users. By selecting all relevant answers, you ensure a comprehensive understanding of potential hazards when operating large vehicles or machinery on the road. This awareness helps in preventing accidents and maintaining road safety.
