It is fairly obvious that teen drivers do not have as much experience as those, say, 10 to 20 years older. Even if a teenager is responsible and mature, they simply do not have the same level of experience that is often needed to handle traffic emergencies and the like. Moreover, for a number of reasons, many teens do not always have the best judgment, and they are more prone to distractions.
Largely thanks to law changes, including the development of systems that require teens to take on driving privileges gradually, the number of teenage drivers that have been involved in deadly car accidents has declined. However, there were still over 3,200 drivers between 15 and 19 in 2017 who were involved in fatal accidents. Additionally, in the case of over 300,000 injury accidents, teen drivers were involved.
