In a manual transmission low gear is the first gear you'll use when starting the vehicle when it is parked or stopped at an intersection. As you drive you then shift to second or third accordingly. With an automatic transmission, the gears automatically shift in concordance with the engine RPMs.

Not only that, is driving in 1st gear bad?
Yes some gears can get to high speed in first gear. But you would not drive around all the time in first as the engine would be carrying high revs allot, leading to poor fuel consumption, high engine temperature, increased fluid usage and increased engine component wear.
Beyond, when should you use first gear? Other than on the occasional downhill start, 1st gear is always the gear we use when moving forward from a stationary position. We also us 1st gear when moving along in traffic queues at very slow speeds, which is usually combined with clutch control.
In addition, is 1st Gear high or low?
Yes gear 1 is a low gear and gear 5 is a high gear. Higher gears are required for higher speeds so you don't blow your engine.
What happens if you shift from 5th gear to 1st?
It would depend at what speed you were driving and gear ratios but to put it simply probably you could seriously over rev the engine and destroy it, as well as breaking traction on the driving wheels which on rear traction vehicles would provoke a spin.

The answer is no. You should not depress the clutch (disengage transmission from engine) EVERY TIME you brake or slow down. But that also does not mean you should NEVER disengage the clutch when braking or slowing down. ... Do not press clutch every time you need to slow down.
Yes, you can shift from D to L while moving in an automatic transmission car. ... The transmission simply won't shift to a lower gear above a certain RPM for each gear.
Using the third gear while driving at a low speed will help you to achieve a higher rev to which the car will respond better. Leaving the gear in D while you are driving in the city means overwork for the transmission. It will have to shift from the fourth to the third gear when you need an extra jump.
Ideally, you should approach the incline in fourth or fifth gear, while accelerating the car at about 80 percent power. Warning: Use caution when climbing a hill and ensure that you do not gather too much speed.
It refers to the rotational speed of the engine when it is divided by a gear ratio greater than
1:1. ... Typically, gear
reduction reduces the speed of rotation but does
not affect horsepower
. Automotive machines produce power over a limited number of rotations, measured in RPMs.
In effect, the gearbox is reducing the speed of the engine greatly but increasing its force in the same proportion to get the car moving. Once the car's going, the driver switches to a higher gear. More of the engine's power switches to making speed—and the car goes faster.
Below about 1,200 rpm the engine will cruise quite well on a level road but will probably not pull a heavy load up a hill and will not accelerate quickly. So you use a lower gear and let the engine run at about 2,500 to 3,000 rpm. At that speed it will be pulling well and not using too much fuel.
Most of the modern cars won't start if you are not pressing the clutch pedal. This is a safety measure which is employed to prevent a car from accidentally starting in a gear. The starter motor gets engaged only when you press the clutch apart from holding the key or pushing the start button.
It's a feel and practice thing so don't worry about it, as you get more experience and sensitivity you'll get better and better and eventually you'll barely slip your clutch in starts. In any case 1,250 revs are not that many.
You can block gear change from 4th to 1st for example. It's also possible to 'block' gear change up if you have enough speed for that gear. 'Block' gear changing (also known as 'selective' gear changing) is less work for you and better for your clutch and gearbox.
