What is the purpose of the L gear in a car?

The purpose of the L gear in a car is for use on steep slopes, waterlogged roads, bumpy surfaces, speed-restricted roads, congested roads, and when starting with a heavy load. Generally, automatic transmission cars have five gears: P, R, N, D, and L. P stands for Parking gear, R for Reverse gear, N for Neutral gear, D for Drive gear, and L for Low gear. Precautions for driving an automatic transmission car: 1. Do not coast in neutral gear, as the engine's braking effect will be lost, vehicle control will decrease, and it may cause excessive damage to the clutch system, leading to burning and erosion of the pressure plate and bearings; 2. Do not shift directly from a high gear to a low gear; instead, downshift gradually. Gradual downshifting reduces the load on the engine and transmission, thereby extending the engine's lifespan.
That day I was driving on a mountain road and encountered an extremely long downhill slope. Thankfully, I used the L gear. This thing is basically a low gear—when you shift into L, the transmission locks in 1st or 2nd gear and doesn’t upshift. Going downhill, it helps control the speed using engine braking, so you don’t have to constantly ride the brakes. On a 10-kilometer continuous downhill stretch near us, the brake pads could practically roast sweet potatoes, but using L gear makes it much easier. Another time, I got stuck in mud out in the countryside—shifting into L and flooring the gas, the wheel torque instantly kicked in, and I got out easily. Just remember two situations where it’s most useful: steep downhill driving and when you need high torque. Of course, you’ll hardly ever need it for normal city driving, but in critical moments, it saves your brakes and keeps you safe.
