What is l in car gear?

"l" in car gear stands for "low" gear. It is usually found on automatic transmission cars and trucks. It allows the driver to attain maximum torque at low speeds, and it's ideal for driving in steep or hilly terrain, towing heavy loads, or navigating slippery surfaces like ice, mud, or snow. In low gear, the car's transmission will shift at lower revs and the engine will produce more power, making the vehicle move more slowly but with greater force. It's important to note that low gear should be used only when necessary, as driving around in low gear can cause excessive wear on the transmission and decrease fuel efficiency.
