The Insurance Institute for Highway Safety (IIHS), those fun-loving folks who crash vehicles in ways that the federal government doesn't, has found what it says to be inadequate head and neck protection for minivan occupants in rear-end collisions. Models from Chrysler, Toyota, and GM received "poor" ratings for their performance, while other models received the same rating for headrests that had a small range of adjustment. The Ford Freestar and Mercury Monterey are the only two vans tested that received the "good" rating. There were no SUVs, wagons, or crossover vehicles tested, although it seems logical that they may suffer from the same problem as well. Additional info on the testing can be found in the IIHS's press release.
