I have North but no house, East but no sunrise, I have West but no gun, South but no mouth. What am I?

I am watched more closely when people want me to move faster.

I brave the splash, the dust, and snow, And keep your vision clear below. Strapped on tight, I’m ready to go. For pool or slopes, I steal the show! What am I?

For preventing death from high falls, or jumping out of planes like goofballs.

I can be traded for a minor gain, Or sacrificed to clear the path. I step straight forward, striking sideways, Quietly bearing the battle's wrath. I am the smallest on the board, Yet reach the end and I become a queen.
