Both field observations of passengers in cars and accident analyse were conducted to clarify the influences of passengers on automobile accidents. Items investigated in both studies included the age and gender of both driver and passenger, and the number of passengers. We used data on accidents occurring in the Tsukuba area (N=957), where observational studies were conducted (N=2682). An accident case study (N=206) was also done to examine the types of passenger-related effects. Log-linear analysis indicated that accident risk was higher when carrying two or more passengers or when driving alone than when carrying only one passenger, and risk was also higher when males or children were passengers. These passenger effects were discussed in terms of communication, distraction, and conformity to passenger norms.
