Snugly across the upper thighs.

  1. Across the stomach
  2. Across the hip bones and belly
  3. Snugly across the upper thighs ✔

Why: NHTSA says the lap belt must lie snugly across the upper thighs, not the stomach. A belt across the soft belly can hurt a child in a sudden stop.

Huh, didn't know that: NHTSA says a child who fits the belt properly can stop using a booster seat.
