As more states allow heavier trucks on interstates, safety and financial benefits debated
PORTLAND, Maine (AP) ' Freight trucks are getting heavier on the nation's highways.
A vote last week in Congress made Maine and Vermont the latest states where trucks weighing more than the federal limit are being allowed to rumble down interstates.
The official weight limit on federal highways is 80,000 pounds. But heavier trucks are allowed on interstates in at least 20 states.
Critics say heavier trucks make highways less safe and damage roads and bridges. They also claim the latest weight increases will spur the trucking industry to seek higher limits elsewhere.
But others counter that allowing heavier trucks makes highways safer because fewer trucks are needed to move the same amount of goods. And they say it'll cut pollution and reduce the cost of doing business.
