The vulnerability of motorcyclists makes them the user group with the highest likelihood of a fatality on roads, a significant proportion of which occur at unsignalized intersections. The current research compares the scanning behaviors of two cohorts of participants at two different intersections involving a right turn. This on-road study included two cohorts: a ‘driver-rider’ group consisting of 20 participants who were both, licensed to drive and held an endorsement to ride a motorcycle, and a second ‘driver-only’ cohort comprising 10 participants who only held a driver license. Two types of comparisons were made: the number of anticipatory glances of the driver-rider at the two right intersections, both before and after the intersection, were compared when riding and driving across the same two intersections. Drivers-only completed the test route once while the driverriders navigated the same route once while riding, and a second time while driving, the exact order counterbalanced across all participants. The results showed that driver-rider made significantly more glances to the left when riding compared when driving after the intersection than before, while they made more glances to the right after the entry than before the intersection. Key Words: field study, motorcyclist behavior, driver-rider, anticipation, right turn across path
