Final Answer:
It is possible to shift down more than one gear at a time when the clutch lever is squeezed. This can be done when coming to a complete stop.
Step-by-step explanation:
In the context of manual transmission vehicles, when the clutch lever is squeezed, it disengages the engine from the transmission, allowing the driver to shift gears. The question suggests the possibility of downshifting more than one gear at a time. This technique is commonly known as "block shifting" and is used when coming to a complete stop. Block shifting involves shifting down through multiple gears in quick succession without releasing the clutch between each shift.
This technique is often employed by experienced drivers to efficiently downshift while decelerating, especially when approaching a full stop or navigating through traffic conditions that require lower gears.
