Selecting a lower gear when driving through curves is beneficial for maintaining control and stability of the vehicle. When in a lower gear, the engine provides greater resistance to acceleration, which helps to slow down the vehicle without relying too heavily on the brakes. This not only enhances control during the turn but also reduces the risk of skidding, as the engine's braking effect assists in managing the vehicle's speed more effectively.

Additionally, driving in a lower gear keeps the vehicle in the optimal power band, allowing for quicker responses when acceleration is necessary, especially important when navigating a curve. This approach can lead to a smoother and safer driving experience, especially in larger commercial vehicles that may require more time to maneuver than smaller cars.

While considerations such as reducing fuel consumption or preventing skidding may come into play, the primary focus in this context is on ensuring adequate control and safety while navigating curves.
