In 2 studies, college students were socially influenced to be risky or not in a driving simulation. In both studies, confederate peers posing as passengers used verbal persuasion to affect driving behavior. In Study 1, participants encouraged to drive riskily had more accidents and drove faster than those encouraged to drive slowly or not encouraged at all. In Study 2, participants were influenced normatively or informationally to drive safely or riskily. As in Study 1, influence to drive riskily increased risk taking. Additionally, informational influence to drive safely resulted in the least risk taking. Together, the studies highlight the substantial influence of peers in a risk-related situation; in real life, peer influence to be risky could contribute to automobile accidents.
