Which gears must be used when preparing to make a sharp turn?

When preparing to make a sharp turn, the optimal gear to use is generally a lower gear, which provides better control over the vehicle. Lower gears, such as first gear, allow for increased power and torque, which are essential when navigating tight corners or sharp turns. In this context, using the first gear enhances the responsiveness of the vehicle, making it easier to steer and control speed effectively.

Additionally, using gears like the third and fourth can also be suitable under certain conditions, as they provide a balance between speed and power. Higher gears, such as fifth and sixth, do not usually offer sufficient torque for sharp turns and can lead to loss of control.

Therefore, selecting gears 1, 3, 4, 5, 6, 8, 9, and 10, as indicated in the chosen answer, captures the appropriate range of gears that allow for better maneuverability and stability when making sharp turns, while also considering the need for speed control.
