The Transportation Department proposed prohibiting commercial truck and bus drivers from using cellphones while behind the wheel.
The rule would affect approximately 4 million drivers, who are already banned by the government from texting while working. The proposal is the latest move in Transportation Secretary Ray LaHood's stepped-up campaign against distracted driving in which he has questioned cellphone use in passenger cars and "hands free" communications technology.
