What fraction of crashes involving teens are not the drivers themselves?

• A. 1/2
• B. 1/3
• C. 2/3
• D. 3/4

Answer: (C)

This question tests how to read and apply a proportion from teen crash data. Two-thirds means about 66% of crashes involving teens involve someone other than the teen driver as the party in the crash. In other words, in roughly two out of every three teen-involved crashes, another person or vehicle is part of the incident, not the teen alone. The remaining crashes are scenarios where the teen is the primary driver in the incident without that external participant, so the majority involves others. The other fractions would not match that idea of a majority: one-half, one-third, or three-quarters would describe different shares and don’t fit the statement given.
