New York became the first state to ban drivers from using hand-held cellphones while driving in 2001.
The Empire State ban applies to all drivers, whether they are teenagers or adults, operating any kind of vehicle.
Violations may result in a $150 fine.
Drivers may be pulled over and cited if they are seen talking on a hand-held phone while operating a car; a citation for texting can be issued only if the officer has another reason to pull over the driver.
Hands-free cellphones are OK.
