WALCOTT, Iowa - Imagine driving behind a truck not able to speed up.
"People go around me at 70 mph and give me the obscene gesture because I`m going too slow," said John Woolsey, truck driver.
The National Highway Traffic Safety Administration has proposed a regulations that would force trucks to install a device to limit speed to 60, 65 or 68 mph.
"It`s most likely going to cause major traffic congestion, it`s gonna cause a lot of aggressive driving because of the time limits we have in-between loads," said Carol Stillwell, truck driver.
Some companies said there is a positive.
"For a trucking company the slower the trucks go the more fuel that we save," said Justin Hopkins, Director of Safety, Omni Specialized.
According to the NHTSA these devices could cost anywhere from $100 to $2,000 per vehicle, depending on when the vehicle was made.
Hopkins said the money they could save on gas isn't work the safety problems they could see on the road if there's two trucks traveling next to each other.
"They get into this battle of trying to pass each other and when they can`t it becomes a lot more unsafe for the motoring public behind them," said Hopkins.
