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?

Your answer is correct because when making a left turn with a trailer or an attachment projecting far behind, the equipment can swing out or extend into areas on the right side. This means that vehicles traveling alongside you on the right (answer 1) and pedestrians walking on the right-hand side (answer 2) could be endangered, as they may be hit or squeezed during the turn. Vehicles behind you (answer 3) are generally not at risk from the side swing, but could be affected if you suddenly slow or stop. Always be aware of the extra space your attachment needs, and check your mirrors and blind spots carefully before turning. This rule helps prevent accidents with other road users close to your vehicle during wide or long turns.
