The involvement of teens in driving accidents reflects the delay in maturation of the ventral striatum, which causes under development of cognitive skills
researchers have identified two situations in which high arousal in teams is very likely when driving with their friends
young drivers, do not get a full license until they have completed an extended period of unsupervised driving
firstly, they are always supervised, then they could be unsupervised during daylight and finally they receive full privileges after reaching age 18, and passing stage two
usefulness
One of the most useful restrictions is on the number of passengers allowed
Friends are initially not allowed and in stage to only with an adult present
This is response to heightened physiological arousal caused by the presence of friends that makes risk taking more likely
Practicality
peden analyse the various components and concluded that the single most significant element is the extended periods of supervision
It appears the longer it takes teens to drive independently, the less risky their behaviour is
