This study gauged the safety of drivers' performance when using guidance devices of varying complexity and mode of presentation. The details of the method and procedure are described, and the results are presented. It was found that in general the older drivers performed less safely. They drove more slowly, had larger variability in lateral placement had longer reaction times to the guages, were more likely to be in the other vehicle's lane after the turn, and were more likely to make navigational errors compared to the other age groups. The age factor interacted to a great extent with the loading factor. Treatment effects are also discussed.
