Virginia Senator John Warner asked Energy Secretary Samuel Bodman to look into the possibility of reimposing a national speed limit to save consumers some bucks.

In 1974, Congress set a national speed limit of 55 because of energy shortages. The speed limit was repealed in 1995 when crude oil dipped to $17 a barrel and gas was only $1.10.

With gas being $4.09 and oil $145 a barrel, lawmakers are wanting to do something. But will it actually work?

"If it will help save on gas, yeah I'm for it. They ought to be able to bring the prices down to be able to help the truck driving industry because they really need it," Keneth Mapp, a truck driver said.

"Saving on gas would be the best thing for the country. The Senators and everybody needs to build more refineries and drill for more gas you know. Cutting the speed limit down only means one thing, you're going to have people going that much slower," Albert Durant said.

"I don't think it's going to make that much difference. We really need to look at ways to change the efficiency of cars and then I'll think we'll see a lot better savings," Eileen Mortenson said.

The Energy Department says that fuel efficiency decreases rapidly when traveling faster than 60 miles per hour. Every additional five mph over that according to Senator Warner will cost Americans an additional 30 cents per gallon.
