Cell phone use has grown higher in among teenage drivers in the US state of North Carolina after a mobile phone ban on young drivers was enacted, according to a new study.
The study, conducted in two parts, shows that the use of cell phones among teenage drivers has increased despite the fact that young drivers and their parents strongly support the restrictions.
It even revealed that parents and teens believed that the ban on hand-held and hands-free phone use was not being enforced.
Based on their observations, the researchers came to the conclusion that North Carolina's law was not reducing the use of mobile phones among teen drivers.
For their study, the researchers carried out telephone surveys of teens and their parents in the first evaluation of a cellular phone law for drivers younger than age 18, which is a part of the State's graduated licensing system.
The researchers point out that 11 per cent of teen drivers were observed using cellular phones as they left school in the afternoon, just one-two months prior to the imposition of the ban on December 1, 2006.
However, five months after the ban took effect, almost 12 per cent of teen drivers were observed using phones, with most drivers using hand-helds.
While nine per cent were holding phones to their ears, less than one per cent had hands-free devices. Two percent were observed dialling or texting.
