As gas prices have soared across the country, some politicians have floated a potential solution: temporarily halting the collection of taxes charged at the pump.

That includes proposals to suspend the federal tax of 18.4 cents per gallon, as well as state taxes that average about 39 cents per gallon.

The national average for a gallon of gas is currently $4.22, according to AAA. That’s up from the $3.61 average drivers saw a month ago and $2.87 a year ago.
