Abstract: International drivers who come from keep-right countries and drive in keep-left countries are frequently involved in road accidents due to unfamiliarity with keep-left traffic regulations. Due to unfamiliarity of the traffic regulation, the driver’s performance and behavior are subject to change. The objective of this study was to explore the effects of familiarity with traffic regulations on driving performance and behavior at roundabouts and intersections. To achieve this in a safe environment, twenty-one male familiar drivers and thirty- four male unfamiliar drivers participated in driving in a simulated keep-left traffic regulation. The factors observed were not fastening the seat belt, entering the driving simulation from wrong side, using an improper approaching lane, not signaling, speeding, driving against the traffic flow and using an improper exiting lane at each roundabout and intersection. Mann-Whitney U test was used to compare driving behavior and performance between the familiarity groups. Unfamiliar drivers made significantly more driving mistakes on roundabouts than unfamiliar drivers. Also, some unfamiliar drivers got inside the vehicle from the passenger side instead of driver side and drove against the traffic flow inside the roundabouts. The implications for familiar and unfamiliar driving can be considered for future research development.
