Previous research studies have proposed a zero risk theory which assumes that car drivers adapt to the risks involved in driving to such a level that they do not generally feel any risk in a traffic situation. "Extra motives" (i.e., those outside the traffic such as time pressure) can influence driver behavior and increase accident risk. This study examines the extra motives assumed by the theory of zero risk for drivers who frequently drive during their working hours. Sales and marketing professionals and construction workers were surveyed regarding traffic participation during working hours, vehicles used on work errands and distance traveled annually on work errands, along with risk factors such as haste, tiredness, poor physical condition, alcohol use, use of medication, thinking about work, use of mobile phone, traffic jams and searching for a parking space. Time pressure, tiredness, thinking about work while driving and use of mobile telephone were shown to be risk factors in driving during working hours. These results confirm the zero risk theory since some risk factors were found that could be explained as extra motives--they are not necessary in driving and they disturb the driver's concentration and affect decision-making.
