It has been well known that the drivers' looking aside behavior is one of the cause of traffic accidents. However, it is difficult to investigate the causal relationship between the looking aside and accident. The authors analyzed the features of drivers' looking aside behavior by using the drive recorder data. It is found that this behavior occurs when three conditions stated below are satisfied. The first one is that the time headway is long enough. The second one is that the required deceleration for collision avoidance is supposed to be small. The third is that there is enough time for the drivers to push brake pedal and stop the car safely. Drivers' looking aside behavior under dangerous situation doesn't always lead to an accident, but when the looking aside period is too long, this behavior tends to cause an accident. In addition to the above, it is found that in the low speed range, drivers try to keep a constant headway distance. The mechanism of this trend is clarified.
