A new bill in New York State will require all school bus drivers to submit to random drug and alcohol testing.
The bill was signed by Gov. Andrew Cuomo on Friday and will go into effect in 120 days.
The bill also prohibits bus drivers from driving within eight hours of drinking alcohol, an increase from the current six hours required by law.
According to the bill, there have been at least four incidents involving school bus drivers being arrested for operating a school bus while intoxicated since Oct. 2012 in New York State.
Under current state law, only ten percent of bus drivers are subject to random drug and alcohol testing.
