How does the number of peer passengers affect the risk of a fatal crash for teen drivers?

The answer indicates that the presence of peer passengers can significantly increase the risk of a fatal crash for teen drivers, suggesting that it more than triples the risk. Research has consistently shown that teen drivers are particularly susceptible to distractions and risky behavior when they have peers in the vehicle with them. The presence of other teens can invite a competitive atmosphere, leading to dangerous driving behaviors such as speeding, reckless maneuvers, and a reduced adherence to safety measures like seatbelt use.

Statistical evidence supports the idea that the more teen passengers present, the higher the likelihood of an accident occurring. This phenomenon is attributed to a combination of factors, including social dynamics, increased likelihood of engaging in risky behaviors, and a tendency for younger drivers to feel invulnerable when accompanied by friends. Therefore, as the number of peer passengers increases, the driver's ability to drive safely and responsibly may significantly diminish, which is why the correct choice highlights that the risk more than triples.
