This quasi-experiment investigated the effects on lane change crashed of nonplanar (spherical convex and multiradius) driver-side mirrors compared to planar mirrors. The analysis was based on 1,062 crashes reported from 1987 to 1998 to Finnish insurance companies, for vehicles with passenger-side spherical convex mirrors and one of three types of driver-side mirror (planar, spherical convex, or multiradius.) The results showed that the mean effect of nonplanar mirrors compared to planar mirrors was a statistically significant decrease of 22.9% in lane change crashes to he driver side. The effects of spherical convex and multiradius mirrors were not statistically different from each other. The nonplanar mirrors were beneficial especially for the high-risk driver groups, as well as for the lane change situations and environmental conditions in which most lane change crashes take place in the U.S.
