Graduated licensing as an option for managing young driver safety.

Young drivers' over-representation in crashes is usually attributed to three factors (National Highway Traffic Safety Administration 2000). * Inexperience: it takes time for driving skills to be mastered and integrated; * Immaturity: characterised particularly by risk-taking and impulsiveness; * Increased risk exposure: including speeding, night driving and drink driving. Graduated licensing systems (GLS) aim to reduce the impact of all three factors. (Author/publisher)
