Oregon Practice Safety Belts & Restraints

Under Oregon law, when may a child stop riding in an approved child safety seat?

  1. A.
    At age 8 or 4'9" tall, when the adult belt fits correctly. Correct
  2. B.
    As soon as the child turns 6, even if shorter than 4'9".
  3. C.
    At age 8, regardless of height or belt fit.
  4. D.
    At 4'9" tall, even if the adult belt does not fit.
The Why

The answer is "At age 8 or 4'9" tall, when the adult belt fits correctly."

The manual ties the exit from a child safety seat to three conditions: the child must be 8 years of age OR at least 4 feet 9 inches tall, AND the adult lap and shoulder belt must fit them correctly. Reaching only the age, only the height, or only the belt-fit condition is not enough. The age-or-height side has an alternative; the belt-fit side does not.

Why the others miss

The traps in the wrong answers

B. As soon as the child turns 6, even if shorter than 4'9".

The age threshold is 8, not 6, and the height alternative still applies. Misreading: Drops the age threshold to 6, which is another state's booster cutoff but not Oregon's printed age.

C. At age 8, regardless of height or belt fit.

Reaching age 8 alone is not enough; the adult lap and shoulder belt must also fit correctly. Misreading: Ignores the 'adult lap and shoulder belt fits them correctly' condition the manual attaches to the age trigger.

D. At 4'9" tall, even if the adult belt does not fit.

Reaching 4'9" alone is not enough; the adult belt must also fit correctly. Misreading: Ignores the 'adult lap and shoulder belt fits them correctly' condition the manual attaches to the height trigger.
