Samenvatting
The study aimed to determine, irrespective of driver licence status, whether young drivers with traffic conviction records at age 21 years differed from those without, with respect to prior personal characteristics measured around the minimum age of licensure (presently 15 years in New Zealand). From a broad range of psychological and social factors, the strongest and most stable predictors were male gender, part time work, rural residence, marijuana use, estimated driving exposure during the follow up period, and early motorcycle riding. Experiences of riding as a passenger with young drivers or with an alcohol intoxicated adult driver were also significant predictors. Some road safety implications are considered.
