This paper considers the validity and reliability of duration and distance estimates, made by a group of learner drivers. The only type of duration estimation that it examines is the retrospective judgement of time, not estimation of an on-going event. 26 male and 14 female learners aged 17 or 18 were tested, using a repeated measures design. Measures of confidence, duration, and distance estimation were made after each of three drives, all using the same predetermined route. Each subject completed drive 1 after five hours' driving experience, drive 2 half way through driver training, and drive 3 a week before the first driving test. Various correlation analyses of the results were made. The results obtained seemed to show that duration estimation and distance estimation are different tasks, which are differentially affected by changes in confidence. The accuracy of the estimates also seems to be related to confidence.
