About 1400 novice drivers, having held a license for 1, 5 or 9 months, filled in a questionnaire about driving behaviour. 130 of them further participated in a video-based hazard perception test. The least experienced reported more driving errors and had slower and/or fewer responses to the hazard perception test. Increased mental load (arithmetic task) during the test resulted in more irrelevant reactions. The additional task resulted in longer reaction times among males and shorter among females. A comparison with a group of drivers who had held a license for several years, showed that the most experienced drivers interacted more efficiently with other road users, as indicated by the questionnaire responses. The differences shown here are likely explanations of the quick decrease in novice drivers' crash risk during the first few months after licensing; the results thus provide support for increasing the quantity of training among learner drivers.
