Final answer:
The Low gear, denoted as 'L', is used for better control and traction on slippery surfaces or steep inclines by providing more power at lower speeds.
Step-by-step explanation:
The gear that is typically recommended for driving on slippery surfaces or when maneuvering up or down steep inclines is the Low gear, also often denoted as 'L' on gear selectors. When in Low gear, the vehicle operates in a lower gear range, which provides more engine power and torque at lower speeds. This extra power and lower speed can improve vehicle control and traction on challenging terrains.
