Abstract
This study investigates the drivers' visual behavior that occurs under conditions of obstacle avoidance with normal and restricted viewing. In the normal viewing, the experienced drivers concentrated on the visual objectives for obstacle avoidance, while the novice drivers sampled the direction of travel quite frequently. In the restricted viewing, the male novice drivers under 20 initiated the compensating visual behavior, but the female novice drivers over 30 displayed the same or a regressive tendency compared with normal viewing. The experienced drivers scanned the obstructions closer in front of the vehicle than the novice drivers in order to increase their intake of visual information.
