The present study examined whether performance in practical driving tests differed when individuals were tested with and without the presence of another testee. In addition, this study examined whether such differences were dependent on the sex of the tested person, on that of the observer testee, and on the order of tests. It was found that for both males and females, a greater proportion of drivers who were tested alone passed the test as compared to drivers who were tested in pairs. Additionally, proportionately more males than females passed the driving test. Only for males was performance also dependent on the gender of the other tested individual. A greater proportion of males who were tested with an accompanying female passed the test than males who were tested with an accompanying male. These results are discussed in relation to social facilitation, gender differences in driving performance, and differences in testing procedures.
