When talking suspension. Which is the left side of the truck? Do you determine it by looking at it or sitting in the drivers seat??

I know what a stupid questions.....I got some parts mixed up and and they are labled right and left?

 

common sense says left side is the driver side

 

Left/Right as you are sitting in the drivers seat.

 

That is what I thought I just wanted to make sure...once I started to question myself!! thanks!!
