U.S. officials of the trucking and bus industry say they support the new ban on texting while driving buses and trucks.
It takes effect immediately. Drivers of interstate buses and large trucks who text while driving could face fines of up to $2,750.
The head of the American Bus Association says a lot of bus companies already have similar policies in place.
In 19 states and the District of Columbia, all drivers are already prohibited from texting behind the wheel.
Transportation Secretary Ray LaHood has been campaigning against texting and cell phone use while driving.
He says enforcing restrictions on texting and cell phone use by drivers will be difficult -- and he's calling on the wireless industry to work with public officials to come up with a solution.
