Maryland’s average price for regular gas has climbed to $4.22 per gallon, according to AAA, while the national average is nearing $4.48.

Congressman Andy Harris has introduced legislation to suspend federal gas and diesel taxes through the end of the year. Combined with a possible state tax suspension, drivers could see relief of up to 64 cents per gallon.

Maryland’s gas tax is currently 46 cents per gallon, while the federal tax is 18 cents.
