What does it mean to "downshift" while driving?

To downshift while driving refers to the process of changing from a higher gear to a lower gear. This action is typically performed to gain improved power or control over the vehicle, especially during situations that require greater torque or when navigating steep inclines and declines. By engaging a lower gear, the engine's RPM (revolutions per minute) increases, which can provide more immediate power delivery and better engine braking capabilities.

This technique is particularly useful in commercial driving, as it helps maintain control of larger vehicles that may be heavy or more difficult to maneuver. Downshifting allows drivers to effectively manage speed while negotiating sharp turns, slowing down for traffic, or descending steep grades. Thus, the action of downshifting is an essential skill for maintaining safety and control in varied driving conditions.
