Arnold Schwarzenegger isn't as much fun as a Governor as he was in The Terminator... just ask California's teen drivers. The former action movie star has signed a new bill -- which we told you about in August -- into law, making it illegal for anyone aged 16 or 17 to use a mobile phone, pager, laptop, or handheld computer while driving a vehicle. Effective July 1, 2008 (the same day that California's ban on non-hands-free mobile-use while driving takes effect), the state will begin to fine offenders $20 for their first incident, and $50 for each recurrent violation. The law is targeting teen drivers due to the wealth of statistics that demonstrate young motorists are more likely to end up in car accidents which result in death. According to reports, 13.6-percent of all fatal accidents are caused by teenagers, and studies show that car crashes are the leading cause of death for people between the ages of 16-19. "The simple fact is that teenage drivers are more easily distracted," said Schwarzenegger in a statement, adding, "We want to eliminate any extra distractions so they can focus on paying attention to the road and being good drivers." He then paused and remarked, "We just don't want to say 'Hasta la vista, baby' to young drivers anymore."
