The national average cost for a gallon of gasoline has drifted around $3.18 throughout the previous four days, as per AAA.

This denotes the most costly Labor Day weekend at gas costs since 2014, albeit a few regions will hit consumers’ wallets harder than others.

California is home to the most costly gas at about $4.39 per gallon. Hawaii and Nevada are likewise among the most costly in the country, with costs in each state adding up to more than $4 per gallon, an AAA representative revealed to FOX Business, referring to regular-grade gasoline.

Indeed, even before the holiday kicked off, AAA forewarned that drivers wouldn’t get any help at the pump during the three-day weekend.

“Outside of Ida-impacted areas, gasoline supply is ample for holiday road-trippers, who should expect to pay the most expensive Labor Day weekend gas prices since 2014,” AAA said.

Here are the top 10 states with the highest gas prices as of Sept. 6:

1. California: $4.399
2. Hawaii: $4.064
3. Nevada: $4.014
4. Washington: $3.892
