In which two conditions should you downshift your vehicle?

Downshifting is an important technique for maintaining control of a vehicle, especially in challenging driving conditions. When approaching a downhill slope, downshifting allows the engine to assist in braking, which can prevent the vehicle from gaining excessive speed. This is particularly crucial for larger vehicles that may have more momentum. By downshifting, the driver can engage the engine's braking power along with the vehicle's brake system, leading to safer downhill navigation.

Additionally, downshifting before entering a curve is beneficial because it allows the driver to slow the vehicle appropriately, thus reducing the risk of losing control while navigating the turn. This technique helps ensure that the vehicle is in a suitable gear that accommodates the sharpness of the curve and the speed required to navigate it safely. Adjusting the speed and gear before entering a curve mitigates the chances of skidding or rolling over.

These two situations highlight the importance of downshifting in enhancing vehicle control and ensuring safe handling during critical driving maneuvers.
