The price of gas has fallen about 30 cents a gallon since hitting a high of nearly $3.80 a gallon earlier this year. The drop is mostly due to declining oil prices.
The research firm Capital Economics says the drop could continue with prices slipping below $3.40 a gallon by summer.
This could also save drivers about $80 billion for the year giving consumers a chance to spend that money on other things to help boost the economy.
