Which headlight beams to use?

This pic (Honda civic ) has 3 switches for 3 different light types. I have the same car.

Which headlight beams to use

Number 1 I should use it at night always. I know that.

But what's number 2 and 3?

Can I use 2 (low beam?) all times at night to help me see in the night or will it blind people?

Is 3 (high beam?) the one that blinds people and I should only use it in very dark areas with no oncoming traffic?

By the way 3 is when you have the switch on number two AND the stick pushed back.

Please answer fully thanks!

John, please capitalize your own name and all proper names such as Civic. John, please read the car manual for the information you require. Also, how come you have not asked your parents for help?

Always use the low beam.
