Fifteen-yard penalties are given for what kinds of offenses?

Answer 1

There are many 15 yard penalties. Blocking below the waist, chop block, clipping, facemask, helmet to helmet hits, horse collar tackles, illegal kicking, leaping, leverage and personal fouls are all 15 yard penalties in the NFL.

Answer 2

15 yards are given for major infractions:

- Personal fouls (unnecessary roughness, hitting a player once out of bounds, etc.)

- Unsportmanlike conduct

- Blocking below the waist

- Chop Blocks (blocking a defensive player at or below the knees while he's in contact with another offensive player)

- Grabbing the face Mask

- Helmet-to-helmet collisions

- Clipping (tackling the ball carrier from behind below the waist)

- Horse-collar tackling (grabbing a player from under the shoulderpads or jersey, and bringing him down)

- Roughing the passer or kicker (hitting after the ball has been passed or kicked)

I think that's at least most of them.
