Kinematic Risky Driving Behavior among Younger and Older Drivers: Experience Matters

This research examined the extent and duration that rates of elevated gravitational force events (kinematic risky driving or KRD) among novice 16 to 17-year- old drivers compared to those of 18 to 20, 21 to 25, and 35 to 55-year-old drivers over a two-year period. Data were sampled from the Strategic Highway Research Program (SHRP 2) naturalistic driving study that recruited a U.S. national sample of study participants. KRD rates and 95% confidence intervals by age and sex were calculated for each 6- month period and total driving. General Linear Mixed models (GLIMMIX) examined interactions by driver age, sex, and driving period. Average KRD rates were twice as high for 16 to 17-year-old novice drivers compared to the two oldest age groups for total driving and the first three 6-month periods. GLIMMIX analyses, which also found that KRD rates in the novice group were higher for males than females and KRD declined after 6-months. Risky driving in the form of KRD rates were higher among novice teenagers compared to older, more experienced drivers for at least 18 months, despite a decline in rates among novices after 6-months. The prolonged period of elevated rates of risky driving behavior suggests the need to enhance novice driver prevention approaches such as Graduated Driver’s Licensing limits, parent restrictions, and post- licensure training.
