The study was conducted to determine the strategy subjects use to avoid a rock in the middle of their lane with a preview distance of 49 m at 89 km/h. In a driving simulator the authors observed subjects' performance in an unalerted situation (one trial per subject), and changes in their behavior over repeated (alerted) trials. There were 12 subjects divided equally by sex and age (younger, middle-aged, and older). For the unalerted trial, eight subjects steered only, three subjects braked and steered, and one subject braked only. Five subjects avoided hitting the rock, all by steering only. Sex of the subject did not affect strategy; however, younger subjects steered more than older subjects.
