Final answer:
To maintain a position of control and safety, the handler should approach a horse from the side, preferably the left side. It is important to approach slowly and calmly to avoid startling the horse.
Step-by-step explanation:
In order to maintain a position of control and safety when approaching a horse, the handler should approach from the side, preferably the left side. This is because horses have a blind spot directly in front of and behind them, but they have greater peripheral vision on the sides. By approaching from the left side, the handler can ensure that the horse can see them and is less likely to be startled or react in a defensive manner.
Additionally, when approaching a horse, it is important to approach slowly and calmly, allowing the horse to see and hear the handler approaching. Sudden movements or loud noises can startle a horse and potentially result in a dangerous situation.
