There is evidence that people who experience moderate-severe TBI and return to driving alter the pattern of their driving compared to pre-injury. They may drive less frequently, shorter distances, and/or avoid some situations (for example, driving in traffic, at night, in the rain, etc.). The lack of consistent information regarding driving safety after TBI is likely related to the alteration that takes place in driving patterns. If people stay within an acceptable range of comfort and ability when driving, the risk is minimized.
