The three most common restrictions were limited driving distance (N = 8),limited driving time (N = 8), and daytime only driving (N = 8). Safe, restricted, and unsafe drivers significantly differed on MMSE (F[2,104] = 10.75, p < 0.001), Trailmaking Part B (F[2,76] = 9.96, p < 0.001), CDT (F[2,98] = 29.88, p < 0.001), and total number of hazardous errors (F[2,97] = 39.06, p < 0.001). Tukey's test indicated safe and restricted drivers scoredsignificantly better than unsafe drivers on MMSE (safe: p < 0.001; restricted: p = 0.008), CDT (p < 0.001), and hazardous errors (p < 0.001). Restricted and unsafe drivers required significantly more time to complete Trailmaking B than safe drivers (p = 0.004). Preliminary data indicate restricted drivers perform more like safe than unsafe drivers. Driving simulationis instrumental in discerning error specific limitations and categorizingpatients as conditionally safe. This clinical evaluation pilots an effective alternative to premature driving cessation. (A) Reprinted with permission from Elsevier.
