To examine motor vehicle crash frequency and risk factors following resumption of driving after moderate-to-severe traumatic brain injury (TBI), data were collected at eight TBI Model System sites. In this cross-sectional study, a survey of driving experiences was completed once by 438 people who were active drivers between 1 and 30 years post injury. Compared to US population statistics, self-reports by TBI participants indicate they were 1.5 to 2.5 times more likely to experience a vehicle crash after resuming driving, even accounting for unreported crashes in the population statistics. Of those who reported crashes, 50% indicated a single crash. Logistic regression indicated that age at survey, years since injury, and perception of driving skills were significantly associated with crashes. Fewer years of driving after TBI, no perception of diminished abilities, and older age were associated with lower crash incidence. Earlier versus later resumption of driving after TBI was not associated with crash incidence. This study benefits from of a larger and more geographically diverse sample than most studies examining this issue. These findings do not justify restriction of driving after moderate-to-severe TBI but do emphasize the need to identify crash risk factors and develop intervention strategies when possible.
