Final answer:
Other motorists can determine your intent to turn by the position of your car, the way your car is moving, and the position of your wheels.
Step-by-step explanation:
Other motorists can sometimes determine your intention to turn by all of the above options. The position of your car on the road can indicate you are preparing to turn, especially if you are in a designated turn lane or close to the corner you intend to turn onto. Additionally, the way your car is moving, such as slowing down or easing towards the turn, can signal your intent to other drivers. Lastly, the position of your wheels can also give away your intentions; as you begin to turn the steering wheel, the direction of your tires can be visible to observant drivers, suggesting you are about to turn.
