Washington residents pay nearly 45% more per gallon of gas than the rest of the country, as WA continues to rank among the top three worst states to fill up your tank.
As of Oct. 21, Washington’s average price per gallon is $4.402, which is $1.355 higher than the national average, according to AAA.
For the greater Seattle area, the average price per gallon of regular gas is $4.662, a whopping 53% more expensive than the national average.
“Ridiculous. Unaffordable. It’s hard to live here now. I’m born and raised here, 50 years. And it’s to a point where it’s hard to live,” an anonymous driver told KIRO Newsradio.
